Truck Heater Problems

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.

Truck Heater Doesn't Heat

I have checked the thermostat and the flaps. The heater hoses are hot and still the heater does not heat the cab. What could be wrong?

More than likely it's the heater core, mine is in the same fix. I have a Ford Ranger XLT and mine went out a couple years ago. My husband bought the core and was told the whole dashboard has to come out! He thought it came out from under the dash, but no, it didn't, what a job to do. I drove my car and he drove his truck and that's why it hasn't been fixed yet. :(

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

I would check the thermostat. You should always replace the thermostat when changing the coolant with a high temperature thermostat. Sometimes people have the coolant changed and replace the thermostat with a low temperature unit and that will blow cooler air. My car was blowing cooler air but the reason was my coolant was down little over a half a gallon.

I can't get heat in the cab of a 1997 Ford Ranger. The heater is hot going in, I don't know if it is a vacuum. Any ideas?

RE: Truck Heater Problems

Many Ford Ranger heater problems can be traced to broken blend doors. The HeaterTreater kit does a complete repair on the blend door malfunction that is common to 96-2004 Ford Rangers. Every Ranger in this range either has, or will have, this common failure. The kit can be found on eBay by searching "heatertreater" (one word). (05/14/2008)

RE: Truck Heater Problems

Pull the inlet and outlet hoses off, use air to blow out the heater core backwards of the water flow. I did this after checking all the other thing mentioned in this forum. My heater now works. If its the blend door thee is a simple way to do a fix without removing the dash. heatertreater.net has instructions and the cost of the kit is about $130. (01/07/2010)
