I am going to harbor freight tomorrow to get some gauges. And I will start logging the ac compressor status bit in hptuners. I will update tomorrow when I get more info. Thanks guys

 

WOW, I have never seen a compressor do that before... with out looking at a set of gauges on the system its hard to see whats going on. I have seen the Safety valve open after the compressor gave up but it bleed out out all the pressure IIRC.

 

Hope you get it figured out. You can search on line to see a pressure to temperature chart. You will see the correct pressures based on temperature.

 

Yea it looks like it just comes from one of the two ac lines connected to the top of the compressor. I really freaks me out because I replaced everything in the ac system except the evaporator and it still does the exact same thing. WTF pulling my hair out. And the guys who charged it said all the pressures checked out. So I will have to see for myself.

 

Did they have any suggestions as to what was going on??? I hope you don't have to do an evaporator.

 

It's replaceable it screws in like a bolt. And yes usually I don't waste my time I put on a new compressor and call it a day.

 

It didn't do it while they had the truck. But then again, they didn't drive it either. Is it a bitch to take apart the dash and take out the evaporator?

 

Those are peanut block fittings on the compressor if you have the incorrect thickness of oring on the discharge line it very well could be blowing past the oring at a certain pressure especially if the line has tension and pulls on the line at a certain angle.

Something was not done right or you have a crap part I have worked on countless numbers of systems on these trucks they are simple and work correctly if put together correctly. This is one reason why I always recommend OE parts. It's going to be something little that's biting you in butt.

You either have a defective high pressure blow off valve or a incorrect sealing oring. If the high pressure valve opens it won't dump the whole charge but it will blow down a good bit of it.

 

Good looking out.

FWIW I ordered a new AC line through the dealer and the machined block was not correct were it sits on the compressor.

 

Yea it doesn't blow much when it happens. Just a split second.
