Dodge grand caravan ac blowing hot air

I had this problem Dodge caravan of AC on driver side while the passenger side blows heat.

We bought a dodge caravan mainstreet used. Right away we noticed that the passenger side and the rear vents only blow heat. The driver side will blow cool air or AC, but the passenger and rear blow high heat no matter what the setting. We brought it back to the dealer and he said it was the dials that were broken. We believed that because the rear dial just spun freely. They replaced the whole interface and it worked for a short time.

There are a few different reasons why the AC might not work in your car. If the air conditioning in your car is blowing hot air on one side and cold air on the other, there could be a simple fix like adjusting the temperature or it could be time to replace a part like the temperature blend door actuator. Problems with the HVAC control module can be further diagnosed with an advanced scan tool , but here are some common reasons why the AC might be blowing hot and cold air on either side despite the set temperature settings. Sometimes the AC blows cold on one side and hot on the other because the settings are set that way. This can be remedied by adjusting the temp on the cold side or vice versa to the preferred degree. If this happens, the module might read inaccurate data, leading to an inaccurate temp and requiring recalibration. If the program needs to be recalibrated, sometimes it can be reset by disconnecting the negative terminal on the battery for about 5 minutes. After this, turn the key on and do not touch any HVAC controls.

Weak airflow to it will reduce its efficiency. Check to ensure that the electric fan over the condenser is engaging. A faulty compressor will not move the refrigerant through the system properly. When a cabin air filter gets dirty, airflow is reduced. If there is no air blowing from your Caravan at all, the blower motor is at fault. The good news is, they are not that expensive and are easy to replace most of the time. The blend door controls how much air-conditioned and heated air enters the cabin. Most modern blend doors are controlled by the computer via actuators. These actuators can go bad. If you hear the sound below, you may have a bad actuator.

I drove back into the lot and all they guy said was, it's a coincidence, the recalls we worked on had nothing to do with that problem The accentuator is a black box about 2" x 2" with a wire harness coming out of it? It was a very frustrating experience. Let it runs for a few min, start the van and check if it works from cool to heat for driver side. The rear driver side may have started blowing cold after I did the first procedure - I can't say for sure since I didn't check it.

I promise to trade in the car, maybe I will try a Ford, this is ridiculous. I actually heard like a vent door open and it changed instantly! Vehicles have already gotten too expensive, they cost exasperatingly more than they are worth, I am still scratching my head as to why. Maybe that was the hot ticket. I can't believe those that designed this vehicle didn't design something to protect this area of the vehicle. FIX: 1. After I fixed mine for the second time I made a rule, never turn it to full heat on the passenger side. May be normal, never noticed it b4. I read all the comments and tried all the fixes.
