I would like your experience on the following problem, as I wouldn't like to start messing arround the electrical circuit of the Jeep.
Visitting the dealer is out of the question, so hold your horses all of you people that were ready to prompt me for it. In my country, I'd rather set fire to my Jeep, watching it burn, rather than taking it to the dealer - I just hope you get the meaning.
Back to the point - The problem is this:
When cold starting the engine, the a/c light randomly flashes on/off status.
No blower is set to operate (fan power OFF).
However, the a/c light indicator shows that the compressor (a/c unit) is randomly switching status from ON to OFF and ON again, in a very rapid rate as well (more than 3 per sec!).
So far, the cure is this:
After manually seting the blower(fan) to 1/4 scale and pressing the a/c button to operate the a/c, then manually again pressing it to switch OFF(a/c) button, the light permanently stays off - as it should be. Then I can turn off the blower and start driving (without praying for my compressor unit to live another day).
My mind is on the relays of the jeep.
However, there is not a clear relay or fuse, dedicated to the A/C operation.
There is a fuse dedicated to the a/c panel operation. I removed it, the light(a/c) was off. However, now the compressor still was messing arround without being able to see since the panel fuse was now removed! - you could only hear it, while cutting On and Off. I put it back in (the fuse) and now I am able to cure the symptom with the method mentioned above(manually On/Off the a/c button).
Second option is the in-dash pcb (that controls the a/c operation, rear window resistance and so on). Maybe the case that the pcb is trashed and operates like crazy.
Anyone had simular problem with the JK a/c controls?
