My 2007 Ford Ranger 4wheel drive V-6 only blowes cold air.
heater blowing cold air
I have a 2009 Ford Ranger 2.3 liter 4 cyl 5-speed manual and the temperature control stopped working. The A/C and defrost work fine, but blow only cold air. The vent and heat are lukewarm to lukecool at best. There is no change when the knob is turned to max cold (blue) or max heat (red). Any thoughts on how to fix this problem?
I have a 1998 ford ranger that had the same problem. The truck ran cold and the heater was cold. It started blowing luke warm a while back then would only blow cold. After checking everything and finding no solution I removed the water pump and found the pump blades worn completely down. the water pump wasn't pumping enough water thru the heater core to provide heat. It also wasn't pumping water thru the thermostat to the heat sensors so I was getting a low temp reading on the gauge. I replaced the water pump and also put in a new thermostat and temp sensors and that solved my problem. My heat is now good and warm and my engine temp reads a good steady temp. Logic would tell you that a faulty water pump would cause overheating problems but that wasn't the case on my truck. The water pump seals were good and the shaft bearings were good so there was no indication of a problem with the water pump. Over time I guess the coolant had eroded the pump blades down to nothing and I wasn't aware until I removed the pump. Good luck with your issue, I hope this helps.
I can't change the heater settings on my '98 Ford Ranger.
Sorry, it is just not clear enough what the problem is. We need more information. Does the switch just stick? A little WD40 might help. If the switch works but the temperature doesn't change perhaps you need to check the hoses. Hope this helps.
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.
I have the same problem on my 91 ranger XLT have not been able to get it. Work last year fine.
I replaced the unit under the hood and the button on dash and the heater still does not work.

By Martin S from Reno, NV
on heat in my 2009 ford ranger 4c
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.
My 2004 Ford Ranger heating doesn't work. The coil does not leak. I have opened and closes the damper door manually. I have opened and closed the bypass valve under the hood, at different times while opening and closing the damper door. It still doesn't work. Any suggestions?

My husband has to remove the hoses and flush them out as trash accumaltes in them. When he does and fills the radiator back up my heater works great again. Hope this helps.
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.
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!
My 1996 Ford Ranger heater will not blow hot air. Any suggestions?
Hubby says heater core is probably stopped up and heater needs to be replaced.
Please help, it's getting cold. The heater is not working in my 1999 Ford Ranger. The heater core is getting hot and air is coming through the vents. I can't locate the transfer door between the heater core and the evaporator core. Where is the actuator? Is it vacuum or electric?
By Mike from Millington, TN
Go to Auto Zone and they will pull up a print out for you and you will find it. The most likely cause is a vacuum door is not opening cause by a broken or loose vacuum hose, listen for a hissing sound and you will find it, it will be under the dash near the big black box (heater box).
How do I fix a 2007 Ford Ranger heater? It has been to the shop and they said there was no problem with the heater core, but only a leak. It still does not work.
The key is you said it does work once in a while and you arent looking for a short or a switch problem and maybe you should. In the dash because it will work sometime and it wouldn't if the thermostat was closed. Think simple I would buy manual for the year of your truck and start reading. Being a female it was the way I had to learn how to fix my own vehicle. I think you'll find a simple small fix. Shucks guys I have fixed a radiator with a potato before.
The heat and A/C on my 2002 Ford Ranger Edge works fine, but the fan does not blow. How can I fix this?
By Gerry D
I own a 2008 Ford Ranger and can't get any heat. I changed the thermostat and the control knob and still no heat.
The AC will not shut off to get heat in my Ranger.
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?
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
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. Good luck, Kathy
The cables won't pull blower open all the way.
