Hey guys, little background. In the past, my car's ac was warm and that kinda went away after I added about two cans of refrigerant last year. I say kinda because the air was tolerable in warm weather but I still felt pretty miserable during the summer heat.
Well recently my AC's blowing warm air again and I want to get to the bottom of this. I've done some searching and it appears that the a/c low pressure switch can be jumped to detect problems but I have some questions.
1. How exactly do I jump the switch? Just stick a paper clip in between the two prongs? And what are the signs that this switch is bad? If the compressor kicks on once I turn on the AC? Problem is though my compressor already turns on (well it cycles on and off, which could be refrigerant related) so how would I identify the switch is bad and not that the compressor is simple cycling on again? If it continues cycling non stop or something?
2. I have a 95 GT. Will a low pressure switch out of a 94 V6 work or are they not compatible?
3. It may come down to this regardless but if I have to add some more refrigerant, at what psi (low side) do our cars like to sit at? My gauge has a green "safe" zone but I'd like to see if there's a specific number for our cars.
4. Lastly, regarding refrigerant, is it supposed to add slow? I distinctly remember adding some last time and it seriously took forever. Could this be because of the low pressure switch or is this normal? Maybe I should add the refrigerant with the switch jumped this time?
I think that's it. Hopefully I can finally get my AC blowing cold in time for the ridiculous FL heat.
Any replies would be greatly appreciated, thanks in advance!
