Re: Restriction?

The radiator fan does blow air towards the rear of the car, correct?

That's what I mean with "visual inspection". If there's refrigeration oil getting out, so is refrigerant.

A leak. Oftentimes a combination of visual inspection, UV dye, electronic sniffer, and soap bubbles must be used to find a leak.

Refrigerant leak. Or refrigerant low to start with after repair.

Re: Ac is not getting cold when ilde

Can you provide both high and low AC pressures at about 2000 rpm? And are all the electric fans in the engine compartment spinning when the AC is on?

Re: Pressure Checks 2000 Excursion

Here’s an update. The fan clutch seems to be doing okay. It won’t move more than an inch or two when cold. I can hear it engage when the truck gets hot. Test that fan clutch when its HOT. If it spins too freely, replace it. Because you stated that misting condenser caused the pressures to quickly d...

Re: A/C quit

First check to see if the AC clutch is even getting positive voltage when AC is switched on. No positive voltage there means no clutch engagement.

Re: No Clutch/Can the system still be evacuated

So somehow the compressor clutch sheered off (missing fender splash guard I am sure had something to do with it) and I need to replace the whole compressor. There is no way for me to check the Freon level without professional gauges. Can the system still be evacuated? Yes, the system can still have...

Re: Compressor Wont Engage

Thanks BSTatics. If I have to i'll bite the bullet and take it to a shop. Heck they gotta eat to right? I'd take it (1) to a real auto AC shop if there's one in your area, not a Brake-O or similar who just has a sign. (2) would be an independent ASE mechanic shop. HOWEVER... had to drive the Burban...

Re: Pressure Checks 2000 Excursion

Vent temp is about 60. The pressures don’t seem to change much at a faster rpm. I forgot to write the ones at at 1500 rpm down. The truck is getting a new turbo this weekend and when it’s running again I’ll check the pressures at 1500 rpm and report back. Thanks for the help. I just want as much pe...
