HIGH PRESSURE CUTOFF SWITCH LOCATED ON AC COMPRESSOR DISCHARGE LINE LEADING TO THE CONDENSOR.THE HIGH PRESSURE CUTOFF SWITCH WILL CUT OFF THE AC COMPRESSOR IF SYSTEM PRESSURE RISES TO HIGH CAUSED BY RESTRICTION IN THE REFRIGERANT CIRCUIT OR OVERHEATED CONDENSOR.MAKE SURE COOLING FAN IS RUNNING WHEN THE AC SWITCH IS ON.THE COOLING FAN KEEP CONDENSOR COOL, IF COOLING FAN DONT RUN.YOUR AC WILL STOP BLOWING COLD AIR.HAVE THE REFRIGERANT SYSTEM CHECK OUT.MAKE SURE YOUR LOW SIDE PRESSURE IS 10 - 37 PSI.

Ac fan motor doesnt work on low speeds only on


I will assume the heater fan also doesn't work on low. You will need to replace the fan speed selector switch

Heater & AC will not blow any air.


there's a resistor pack for the fan that allows it to work at different speeds. does it work on the high setting but no others? if so, it's the resistor pack at fault. it's mounted on the fan under the passenger side of the dashboard. you may have to pull the glove box down and use an extension to get to it. if it doesnt work on high or at all, try to pull the connector off of the fan under the dash, turn the ac on and check for proper voltage and ground. it should just be a plain old red wire and a black wire. the red is power. the black is ground.

How to trouble shoot air condition compresuer


You really want to troubleshoot your AC. Here are some items to follow:
1- Make sure your Compressor clutch work first. You can jump the wire to test it when the engine is off.
When you know the clutch work then you can look for the other things not makeing it activated.
2- It it doesn't work then you know the problem right there.
3- If it works then check the Low and high pressure according to compressor spec.
3- Check your engine temperature sensor. Don't think that your temp reading gauge is coorect then your engine temperature for your AC is working.
4- Check your compressor sensor speed. It has to be in sych with your crankshaft sensor before it allows the clutch engaged to prevent burning your compressor when it is locked up is in freezing mode ( ex.in case some clever people jumping wire to control the clutch bypassing all other rerquirement).
5- If you think these items need to be addressed by professional better then do-it yourself then I have no objection. Good luck on trying.

2002 pont. grand prix-Heater/AC Only works on High


you need a new speed control resistor... this is something you will have to get from the dealer, but you should be able to replace it yourself - it is under the dash on the passenger side mounted near the bottom of the fan motor.. you will remove a couple of screws, and it will come out of the black casing it is mounted inside.

HVAC Blower functions only at highest (4) switch setting


if the blower works on high then its not a fuse it could be the switch or the resistor that cuts back power for the lower settings
