I have a 2000 chevy tahoe, 4.8l v8. I noticed about two weeks ago that the a/c wasn't cooling like it had been and figured that it was low on freon. Today it quit cooling all together. The clutch on the compressor is not 'deploying' when i push the a/c button. I checked the freon, and the range is normal. After messing with it for awhile, I found out that there is no fire getting to the low pressure switch. All of the fuses in the panels appear to be fine. So... my question is, do low pressure switches go bad often, or is there a better possibility that the problem is in the line going to the switch? Any suggestions would be appreciated.
