AC question

Where is the AC control module on a 93 Tracer? I know the ignition module is under the relay behind the battery but wher is the AC module?

Thanks!!

 

I have not heard of a AC module. The air conditioning in most cars is controlled by the Body control module, or the powertrain control module.
Most of these are under the drivers/passenger side door kick panel, or under the hood.


What seems to be your problem?

 

Hey HotinOKC, thanks for the reply.

No AC. The blue light comes on on the "on" switch on the control panel but the clutch doesn't kick in and the engine fan won't come on either. The fan will work when the engine warms up. The blower works anytime. I replaced the radiator but there's nothing that I can think of that I could have screwed up that would effect the AC. I'm not sure how to check the relay either.

Thanks again.

 

Alrighty,

It could be two things, usually.

A high/low pressure sensor is bad (this will be on the high pressure side line near radiator)

or

the thermostatic switch is bad, if equipped (this is mounted in the air box area, usually behind the glove box.

You have checked to make sure you have proper refrigerant pressure, correct?

You can buy the gauge at any auto store. Make sure engine is running and A/C on high when testing.

Having lack of pressure or over pressure will cause the compressor not to engage.

If you have exhausted all these possibilities, check your control panel.

 

Thanks, Mark. I will let you know what happens.

 

There was a broken wire behind the control panel.

Thanks again, Mark.
