I have been searching through the forums and have not yet found an answer to my specific problems. If possible please advise.
Last week my A/C was not blowing cold air. The compressor was powering on, however I did note that the button on the dash did not light up. So I took the Disco to a shop I grew-up working at and had refrigerant added. At this time the pressure in the system was getting extremely high (>400) and in looking at the condenser fans noted that the one on the passenger side was not working.
I replaced the defective fan motor. Now neither fan is working. However, when I jump the fans directly to the battery they both run strong.
I *think* the A/C switch is bad. When I depressed it last week the compressor kicked on. When I depress it now, it no longer does. However, I am green when it comes to Discos and all their various switches and relays, so I would like to ask your advice.
Does this sound like a bad switch, or a bad relay, both, or something else?
How do I actually test the switch? I pulled the switch out, but can't find another switch with the same configuration to try a swap with. I have read people mention jumping the switch to see if the A/C works. Which wires do I jump?
A couple other points: I hear a relay click when the rear A/C switch is depressed, but not the front. Should the condenser fans come-on if only the rear A/C is running?
Thanks for your help!
Salud,
Jon
