If the engine does not overheat there is a problem with the condenser fan motor circuit or (most likely) the fan itself. Check the fan by diconnecting it and applying 12 volts to the terminals if the fan works Check the 50 amp fusible link 2 and the 20 amp fuse 9 in the engine compartment relay box, this is located on the left side of the engine compartment. If these are both good there is a fan controller located on the radiator fan motor shroud which controls the "fan control relay" this is the next likely problem. From there on you might want to bring the car to a mechanic as extensive testing is required between the the PCM, MFI relay, fan control relay and fan controller. Hope this helps

If the fan still works on highest setting only the fan speed resistor block is faulty.
if the fan doesnt work on highest setting check for power at fan while on highest setting with globe test light, as well as checking fuse for fan. 2 wires one power other is earth. if power is there the fan motor needs replacing so long as the earth wire is also ok check with voltmeter on Ohms for continuity should be a couple of Ohms any higher is no good.

What would cause the blower to stop working on the heater and air conditioner?


Either the fuse has blown or the fan is faulty. Could be the switch but unlikely.

Usually a vac leak. I would check for a leak in the HVAC control system and the line thru the firewall to the engine.

Did you replace the thermostat? If it is stuck open the coolant may not get hot enough to be effective.

Overheating and heater blowing cold air.


Heres the answer for the clicking sound

I had the exact same problem, yes it was the heater control valve, the repair was 285.00. The tech that replaced it told me it is a common problem for the Galant. He said that if you keep your temp selector on either all hot or all cold that it keeps constant pressure on the plastic gear teeth in the valve. As they break off one by one you begin to hear that clicking noise as the dont catch. When you finally break off the last one it stops working.

According to him if you always leave the dial at least one notch from fully hot or fully cold you will not experience a failure of the switch

Jeep Wrangler 03 A/C stopped working abruptly


This may be the AC compressor cycling switch is defective. It is located in the larger of the 2 AC lines coming from the compressor, it has a wire connector to it with 2-3 wires. To verify this is the issue jumper the connector with a small piece of wire and see if the compressor runs.

Air conditioner


this is the way the car is designed when the defrost is on it runs the are threw the evaporator with the AC on . this dries out the air to help defog or defrost your windshield. american cars have been doing this since the 80's . the original idea was to work the compressor in the winter. a AC system sitting not being used has more repairs than one that is used all the time.
i hope this helps
