No A/C - I’m Lost...

before a shop recharges it they should put vacuum to it and see if it holds. plus that evacuates all the moisture. most shops won't just charge an unknown system.

So my A/C compressor face plate is now not engaging at all. I removed the plastic caps from the high and low-pressure check fittings and gently pressed down on the ball bearing inside. Got a slight “pffff” out of each (both when the truck was running with the A/C turned on and when it wasn’t). Seems like the pressure is really low in the system. Therefore, I’m kind of thinking that it would be okay to just order the new o-ring set from LMC, start replacing them, then have a shop refill the system and hope for the best. Anyone disagree? Are there any tests that can be performed on the compressor, condenser, TEV, etc or does one just have to pay for the system to be charged and hope it works?

Thanks!

PS - I’ve never had a shop evacuate and refill an A/C system before. I’m anticipating that it will be a couple hundred bucks?

You don't want to open a system unless you are sure the pressure has been reduced to zero. if not, you're going to have a very oily mess on your hands and pretty much all over the place where you happen to open up the system. I would suggest you just take it to a shop and have fixed. If you did not put UV dye in the system that PO probably did.
