On dodge caravan ac is blowing cold in back but hot in front. How do I fix


You need to have the blend doors on the front heating / ac system looked at.. Sounds as if one is not working properly and not switching from hot to cold. It could be an electrical... vacuum... or the blend door actuator itself causing this problem. Some of these door motor/actuators are hard to get at and I would recommend having a pro look at it

Air cinditioning wont stay on, it switches to heat and wont shut off


What do you mean when you say it wont shut off? is it blowing hot air or do you just feel a lite flow of hot air even if you have the settings to cold?

If this is the problem that you always feel hot air at low flow and the ac goes to hot air then i would say one of two things, first if you have the selector to cold and you feel hot air then there may be a problem with the blend door, this door move to allow hot or cold air, the door may be broken or just a bad motor that controls it. keep in mind if the ac system shuts down for any reason the air then will be warm, it will be about the same temp as outside and maybe a little hotter.

this problem almost sounds like the ac compressor shuts off and then you are getting the outside air which is hot, there are many reasons for the compressor to shut off, it could be the compressor clutch heating up and disengaging , this would be due to a bad compressor clutch.

another reason is the fans are not working, the best thing to do is when the system starts to blow warm check and see if the compressor is running, start engine and look at the front of compressor, with ac off the front of it will not move, and then with ac on the front will spin, check it out and let me know, if it blows warm air and ac is not working then it may be compressor problem but if you are getting warm air and the compressor is spinning then it may be a door problem.

This is hard to check with out testing the system, so i listed a few things to check and let me know the out come. also the ac blows cold for how long before it gets hot air blowing out of the vents, good day.

I have a 2005 GMC Sierra regular cab. 4.3 v6 The heater has only been blowing cold air. Checked coolant and replaced the thermostat. No change. AC worked fine this summer. Heat worked fine last...


sounds like you have a bad temperature door actuator. This is a motor that connects to the door and uses inputs from the sensor in itself and the heater control module to open the door from hot to cold. I does take some knowledge on recalibrating this actuator and installing it. if it isn't install correctly it could damage the new part, so just take care

The ac blows hot air in the front and cold air in the back


Either the door that controls whether air from the heater or ac is stuck in between or the ac system is having trouble. Minivans sometimes have seperate compressors for the rear and front.

2005 Dodge Durango Front AC won't blow cold, back air works great


could be the front door for the front air needs to be propped open so that is blows cold, could also be the a/c compressor or a clog somewhere up front in the vents... it could be numerous things, but i would say try propping the door open, if that doesn't work try replacing the compressor... haynes makes the repair manuals for the truck, goto auto zone, pep boys, etc. and pick up the book they have step by step instructions on how to fix the most common problems and all the different systems of the durango... the book will be very helpful, cause if you do your own work you can find everything easily..... hope this helps you...
