I have a 1993 Ford Ranger XLT 3.0 and the heater was working good until a couple of weeks ago. Then it just stopped working and I mean doesn't do anything no matter what you've got the control panel set on, nothing.
I own a 2005 Ford ranger. How do I tell which is screwed up, the temp control switch or the blend door actuator?
Have you checked the fuses? Mine are on the firewall on the driver's side. Easy to access.
I have a '97 Ford Ranger truck. The blower works on high, but doesn't blow heat. The a/c works fine. I replaced the thermostat; that didn't work. Any ideas would be a help. Thank you.
It sounds like your heater core is clogged.. It's usually very expensive and time consuming to repair a clogged heater core. It usually involves taking your dashboard off on the passenger side to get to the core... I would recommend getting a flush kit from your auto parts store (I usually get two) and where the hoses go to the heater core in the engine compartment, hook the flush kit up to both hoses coming from the heater core and flush it in both directions.
I usually try to hook my hose up to hot water to help break any gunk loose. You might also try pouring some coolant flush in prior and let sit to break up any gunk before flushing.
I have only high speed on my Ford Ranger heater fan. How can I fix this?

Hi, my car did the same thing. It is the heat resistor fan speed control switch. t is usually found near the firewall on the passenger side. The part can be bought at most any auto parts place, cost about $35.Google your vehicle/heat resistor fan speed control switch and you should be taken to a page showing you where it is located.
I have a '98 Ford Ranger 4cyl with a temperature control problem. The temperature control knob does nothing with regard to changing the air temperature coming into the cab. I just put a new heater control valve in and it has vacuum to the valve. The blend door is changing to the selected outlet AC/floor/defrost, etc. I only get AC when in the max position, heat everywhere else. Any ideas?

If you Google a phrase like "car repair forum", you might have a better time of finding people who can help you. That's where I got some good advice about a strange noise my car was making, and found out that it was the fuel pump failing.
I have a '95 Ford Ranger. The fan speed controls work, but the AC only works on max air and I can't control the temperature (very cold). The heat works on all other settings and (very hot). The blend door has been replaced .
If you have replaced the bend door then this is a thermostat issue with the car. There is some sort of short in this piece of equipment that should be checked out and replaced.
Sounds like your heat pump, thermostat, or both is on it's way out. Great classic truck!
I had a '07 Ford ranger and I had the same problem at one point. It's also not the first time I hear of the problem.
It must be one of those design flaws and possibly a reason why the Ranger, though a great truck, was dicontinued after 09
Take your truck to one of the auto part stores - Auto Zone, Advance, Pep Boys and ask them to run a diagnostic test. They will usually do this for free and it may pinpoint your problem.
I have a 95 Ranger 3.0 2wd 5spd. I checked the coolant and topped it off and the heater is still not working. The blower works alright and it's just been blowing cold air.
Any idea what I should look at next or a list of what I can check?It could be the blend actuator door.
Normally the hose is under the dashboard and runs behind the glove box. There is a blend actuator door that you need to look at and see if it is working correctly.
I have a '99 Ford Ranger 3.0 with 200000 miles. Heat comes out of the vents until the fan turns on, then it blows cold air.
You could have an issue with the blend door.
In my case it was a blend actuator that costs over $2000 (that was the lowest of the bids) to repair because they have to rip the dash out to replace it. I love the car so I deal with it!
I have a 2000 Ford Ranger v6 3.0 manual. I had a leak from my water pump so I replaced that and the thermostat. Then my heater stopped working, so I did a coolant flush, but it didn't do anything, so then I replaced the heater control valve, still nothing.
Then I just replaced my heater core. The temperature reads normal, but my inlet and outlet hoses are not getting hot. All of the settings work it just won't blow hot air. I'm at a loss.Causes of heater not working.
Step 1
Coolant Level
Step 2
Thermostat stuck open
Step 3
Heater Control Valve
Step 4
Temperature blend door
Step 5
Step 6
It could also be a stripped knob.
You may need to back flush heater core here is a link to you tube on how to do it www.youtube.com/
The heater in my truck doesn't work at all. No air comes through. It's just dead. Any suggestions?
I have a 2007 Ford Ranger Sport with a V6. Last summer the A/C didn't blow much air, for about two weeks. My heater only worked once in a while and for a week now nothing blows air. I've replaced the thermostat, temp sensor, blower motor resistor and the air door actuator. I checked both fuses in the fuse box under the hood and both are fine. Any suggestions? I'm tired of driving in the cold.
I have a 2001 Ford Ranger 4.0 ,4wd. I replaced the 10 amp heater fuse, blower motor relay, blower motor, and three way dash switch. I also swapped around the under the hood relays. Still nothing? I used a test light and it seems there is no power to anything (relays, blower motor, dash switch).
Also my air bag light is on. I was told the seat belt relay was bad a month ago, but then I replaced the fuse and the air bag light went out. This happened many times and now the fan is not working at all after replacing all of the parts listed above.There are a couple of Ranger Forums that may be helpful. I've gone to them in the past and sometimes gleaned helpful info that helped me fix my 2008 Ford Ranger. One of them is ranger-forums.com. Also, there is 1aauto.com. 1aauto sells parts but they also have a "online chat" option where you might find some answers.
Any one have any ideas why my heat will not work and what I mean is sometimes the air will blow and sometimes it won't. It's a Ranger XLT.
How do I back flush a heater core for 99 Ford Ranger? Can I do damage, if I do it wrong?
By Mike H. from Boston, MA
What I normally do is buy two flush kits that you can normally get at walmart or you auto parts store. I hook the "T" connector to both hoses going to the heater core in the engine compartment. I personally try to hook my Jose up to a hot water source, I also like to pour coolant flush into the core prior to flushing to help break up any gunk.
Also you want to punch off the hose on opposite side of "T" connector to force the water towards the heater core and not the toward the engine as this can mess up the thermostat and make sure that the second hose coming from core can dump into a container and is not attached towards motor or the gunk that will break free can go into motor and cause damage.
I've done this a hundred times and have saved tons of money from having to replace heater core. Total cost with new antifreeze and two flush kits should be around $30 rather than $400 for new heater core and $1500 for labor. It's definitely worth doing. You can also find videos YouTube and other sources (some prefer to use compressed air rather than water).
The only time you really need to replace heater core, is if it is leaking which in this case, your passenger side floor will most likely be wet).
The block won't even heat up. I replaced the thermostat today and the old one was in pieces so I thought that was it but it still won't heat up. Any advice?

Mine has had so many heater problem, when I had that particular issue I for me it was as simple as a flush ... But a intense long flush. I got a hose and filled up a (Metal bucket) then boiled water wile that was cookin I opened the drain valve and radiator cap. Let it drain and filled up with distilled water and drained again and again.
Slightly closed drain to just a slow stream and poured in the boiling water turned on the car and let cycle. But remember the drain is still open so keep adding water when it starts to get really clean looking open can of sea foam pour 1/3 of bottle in radiator close drain and cap let cycle after a few min open drain (be careful under pressure and very hot) once drain valve is open for a few seconds, enough pressure should be gone to open cap add more regular distilled water till clean water continuously drains.
Shut drain cap and fill up radiator but add a little more of that sea foam to it and drive car around for 15-20 alternating speeds to make motor work and cycle have heater on high fan and heat throughout entire proses then check fluid level it should be low top off and wait 2 days and re-do proses u will prolly think this is re-donkulace Lol, but it really made mine work great once the car heats up.
You will need:
A can of sea foam
Found at most auto parts stores it's a white bottle red writing.
Remember 1/3 in with boiling water then drive hard or so! Then add another splash when filling coolant put remainder in gas tank I use it every other fill up :;
At least 4 gallons of distilled water depending on times you plan to flush and rinse
And finally what ever choice of coolant you choose.
Now my new problem is my thermo gauge never goes above cold line and also cold air is coming from some where in high speeds heater is amazing till I hit about 65 and up then cold It's like it can't keep up with the air entering system. Well it's up to you to try it or not but no mater my tips or anyone else do your home work on every thing you are informed about hope u get if fixed!
The AC will not shut off to get heat in my Ranger.
By D.B
Have it checked or do it yourself, to see if something is wrong with the compressor. Also have them check the thermostat. Hope this helps.

My 2008 Ford Ranger heater will not blow heat on the floor. Do you know what this could be or how it can be fixed?
By Carolyn
Does anyone know why it would not work? If so please let me know, it is getting cold and colder. Thank you.

On my 2004 Ford Ranger XLT the a/c won't change to heat.
By Dewey from Wylie, TX
The cables won't pull blower open all the way.
By Cathy
I have a 97 Ford Ranger that has heat, but the blower is not working. I replaced the resistor and blower motor. What else could it be, the relay? or a vacuum leak?
By Harold
My 95 Ford Ranger pick up was running hot. So I changed the thermostat and the radiator cap, and checked the anifreeze and water levels. It still ran hot. So I then changed the water pump, flushed out the radiator and added more antifreeze and water. Now it still wants to run hot. What else do I need to check?
By Jamie from Trenton, GA
I have a '98 Ford Ranger. I am having problems with the temperature control of the heater system. The heat is stuck on. I have heard and read of problems with the heat and a/c blend door. I don't think this is my problem because it seems like I had shorted out my trailer lights and then the heat control problem started. Is there a relay involved in this that could have burnt out? I have already replaced the blower motor resistor on a recommendation of an auto parts store employee.
By Rodger from Fruita, CO
Check the thermostat, fuse, and coolant level. It could possibly be a plugged heater core. This is a page about 1994 Ford Ranger heater is not working.
This is a page about a 1997 Ford Ranger heater not working. Do you have a 1997 Ford Ranger with heating system problems? Here is some advice, if you want to try diagnosing the issue.
