testing AC pressure sensor?
Does anyone have any information on the ac pressure sensor that might help with testing if it is faulty? pin out names/values would be great
Now that it is getting warmer I would really like to get my ac working again. I know the system works when I jumper 12v to the compressor I get nice cold air but in the cabin it will just not turn on. The red light on the 'ac off' button is permanently lit.
Any input is appreciated.

Any chance you could get a star computer hooked up or equivalent? If so it should tell you why the system refuses to turn on the compressor. That said I have seen plenty of posts about the ac pressure sensor and if the system pressures check out that is probably the issue.
