When the control module burns out it will only work on one speed.
The models with the automatic temp. control will cost approx. $300.00
Easy to change. You will find it near the blower motor.

Front AC cold but Rear AC very hot


Not likely, but Is Hot water flowing to heater coil in back? How hot is "very hot" Is it a refrigerant line? If a refrigirant line, Very Hot means it is hot gas from the compressor that "should be going to the condenser coil usually in front of the radiator. It's almost impossible for that Hot refrigerant gas to go to the cooling coil in the back unless you had some repairs done and they weren't certified. My guess is the radiator hot water is not being controlled properly, due to bad valve or control system components.

Driver's side air blowing warm, won't change


Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

This car has the automatic temperature control system


The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.

The air vents are control by vacuum line and or linkage.

Listen for hiss or feel for vacuum leak under the dash,

Feel for broken linkage(s) that are close to the vents.


WORK BACKWARD if you have small hands to feel out where is the missing link.

Rear climate control fans blowing cold


That sounds to me like your vent "tubing" is disconnected somewhere along the line. I am not sure exactly how it is set up in the vehicle you are driving, but I am certain fixing it will involve taking apart most all of your interior then putting it back together after a 10 minute fix.
