A/C Compressor is leaking after repair shop…

[qx4guy333]

Hello, I have a 1998 Infiniti QX4 3.3 liter engine. I took my SUV into the shop to have the timing belt changed. They had to disconnect an A/C line that was in the way of the timing belt cover. When they were done they said they did an evac/recharge. The day it came back there were green drips under the compressor, which got progressively worse, and now (couple weeks later) the A/C is not blowing cold at all. I took a look at the A/C line that they disconnected and I didn’t see any green leaks at the connections. All the drips are coming from underneath the compressor. Do you think they could have caused this or do you think it’s just a coincidence? The A/C was working fine for over a year until the day they touched the car. Everything (and I mean everything) in the A/C system was replaced a year ago except the compressor.

Someone suggested that I take the SUV in for a UV test thinking it’s the little o-ring seal where they disconnected the line, so I did. They found it is not the line or the o-ring seal, but that the compressor is leaking. My question is do you think they overcharged the system and this is what caused the compressor to leak? According to the instructions that come with a compressor it says, "Compressor failure can occur because too much refrigerant causes high head pressure which will destroy the compressor." Do you think the guys who did the repair job put too much refrigerant? Is it even possible? Isn’t there some kind of safety built in that would prevent them from adding too much refrigerant (1998 Infiniti QX4)? It's the only thing I can think of that they might have done wrong, but I don't know enough to make this conclusion. Do you think it's just a coincidence instead?

The guy seems really honest so I would hate to accuse him, but I also don’t want to get stuck with a bill all because they did something to make my compressor suddenly leak.

Thanks in advance for your help; I really do appreciate your time.

aloha to keep it simple, somebody gonna have to add a dye in the system and take a UV light to check where the leak is coming from.

who knows what the guy did to your system? he could have overfilled it, could have done too little or too much compressor oil as well.... my advice is take it to someone who is experienced with A/C and trustworthy....
