1993 Tracer 4 cylinder with automatic

My sister swears that last week the A/C was working. I replaced the radiator and now she says the A/C doesn’t work.

When I turn on the A/C the blue light on the on/off button lights up as normal but the radiator fan doesn’t come on and the clutch doesn’t engage. Neither does it work when I hit the defroster. The radiator fan does work to cool the engine and the blower motor fan works.

I went to check the fuse but I have never seen this type before. It is a black object about ½ x ½ x 1 inch high and I couldn’t remove it to check it.

What should I look at and where is the control module and how would I access it if I need to check it?

Thanks!!

It could be a few things:

Low on refrigerant

High/low pressure switch

Control panel

Thermostatic switch (in airbox)

What you were looking at was the A/C relay, not a fuse.

I just had the same problem in my wifes Stratus and it turned out to be the control panel.

When replacing the radiator, did you remove the A/C lines going too the condensor?

Also, you can test the compressor by putting a jumper wire in the relay cavity, but get a wiring schematic for the relay box first. I think it's pin 87 and 86a, not sure.

 

Mark,

No, I didn't remove the A/C lines to the condensor. I'm hoping it was something simple or it's just circumstance.

Thanks.

 

If the radiator was removed, the wire to the AC compressor clutch may have been disconnected. If so, just plug it back in place.
