I'm having trouble with my '04 GT. I have searched here and it sounds like I am low on R134. The ac worked fine last year, but now it does not. I press the button and the clutch does not kick in, but the light lights. I checked the fuse, and its ok. I don't see any obvious leaks and all the hoses seem to be connected tight. I realize that is no guarantee to a leak free system, however, I made one call the other day and the price I was given was over $400 to check and charge. That is probably what I should do, but I just don't have the money to get out the door of the shop right now.
I am hoping that I can get a can or two in the car and hopefully next year I can get it checked out. With the compressor not kicking in, I assume that I have to jump the low pressure switch with everything ready and connected to get the system to receive the gas. When I look at the switch, it looks like it has 4 (edit - 3 actually) contacts. Which are the correct ones to jump?
I'm familar with cars, so working on them is not an issue, however they have all been 1987 or earllier vintage to this point. I really would appreciate a quick pointer or two,
Thanks,
Scott Barrett
