The Control Module In The Dash Is Known To Go Bad.
These Can Be Found For As Little As 29.95 And Up to 500.00 Plus The Cost Of A Vw Tech Install
But Can Easily Be Done Yourself By Plugging In A Wire Harness And Hooking Up The Wires For The Temp Control And The Defrost Selector.

Also You can find The Blower motor On The Passenger side floor Back Wall
You Can Also Test The Blower With A Simple 12Volt Car Battery

Why does My thermostat Not switch between ac,heat,defrost . there's cold air coming out of vents but not cold enough to be ac. Initially when this started the ac was blowing hot air


If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

Why does my pontiac torrent overheat when ac is on


sensors......Water temp sensor, air flow temp sensor, MAP sensor, Idle speed control solenoid, throttle position sensor, O2 sensor.........
Engaging AC draws on power from your motor, resulting in the ECU having to compensate to keep revs stable. Increased revs result in increased air flow, water flow, fuel flow & exhaust emissions.
Check belts for your AC pump first, as the same belt may drive your water pump. If it slips under load when the AC is on, ..................... Say no more. Next replace Water temp sensor. No luck..... ISC solenoid....

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

- In case of multiple problems, the recirculation indicator will indicate only the DTC with the least number of blinks.
- In case of an intermittent failure, the heater control panel will store the DTC until the ignition is turned off.

1995 chevy blazer heat, ac will not blow air


yes the heater controls are vacum however the blower motor is not. a new control panel is an option and may fix it. if it was my blazer i would first check the fuse boxes onder the hood and in the side of the dash driver side. if they are good i would go to the nearest auto parts store and buy a test light. this will aid you in making sure what the problem is before you go spending money on replacement parts. the blower motor is in one of two places. its most likely under the dash on the passenger side. there is a cover that you will have to remove directly under the glove box. once removed you should see a large red and a large black wire. these are the power and ground for the blower motor . in some gm's these wires go into a resistor. the harness plugs into the resistor and the blower motor wires come out of it. ok now that we are a little bit familiar with our suroundings the red wire i told you about is the hot wire if you ground the clamp on the test light to the door hindge. (make sure its a good ground by touching the positive batter terminal. if the test light lights its a good ground )now unplug the blower motor and touch the metal posts in the end of the plug that belong to the red wire. if it lights when the key is on and the blower control is on in all posisions you need a blower motor. if it does not then you need a blower motor resistor.
