Hi I am a newbie here. I would appreciate anyone's expertise as I have none. I took the 850 GLT in to be recharged, and I know I am a pessimist but next thing I know both low and high pressure switches are 'leaking', and i am being charged like 33% markup for both parts.

I am just frustrated because I don't know what questions to ask them. Should I have asked to see the switches? I took the car into a local shop for convenience, also because apparently dealership diagnostics would cost $240 (mine started out $150, now I just paid $350 with $100 more to come).

How could both be broken at the same time? The rep kept using the word 'leaking'. Was he trying to dumb it down for me? Could the switches (held in by rubber sealant or something he said) really be out at the same time?

Last summer the air was working fine. Thank you so much in advance!

this is a 96 car - forgot to mention that. also i truly don't remember if the switches were ever changed before but i don't think so. thanks.
