Re: Fog and refrigerant blown out of vents during recharge

Soapy water is fine for leak checking, but I've never used nitrogen for pressurization. I'm sure it works for that, just that I've never tried it. I used soapy water about 18 years ago to confirm a leak in the evaporator of my 1988 Mazda truck. Nitrogen could be used for leak detection, I'd hold un...

Re: 75psi on high and low side

It sounds like the AC clutch on the compressor is not engaging. Is the CENTER part of the compressor actually turning, or just the outer rim of the pulley?

Re: Adding UV leak detector question.

When adding freon or leak detector to my vehicle's AC system does the AC compressor clutch needs to be engaged either while or before I'm adding? Not if you add the UV dye BEFORE you evacuate and then add freon. And same if your vehicle uses R134a. Or if you add a can of refrigerant containing UV d...

Re: Not blowing cold air after charging

I recharged the AC and it blew cold air for several hours after that it stops blowing cold air. EXACTLY what did you add ???? I sure hope it did NOT contain any sealers !!!! The right way is to charge refrigerant (only) by weight; UV dye is OK. I must ask why you needed to recharge in the first pla...

Re: 2014 Land Cruiser AC Problem

The broomstick trick did not work. OK, so the AC clutch stops engaging when things get too hot, like in traffic. Proved by the broom handle test. So - if all your fans/fan clutch are fine, then possibly the AC clutch gap is too wide (broom test); some AC clutch can have a pacer removed to make this...

Re: 2013 Sentra AC problem. Compressor turns on but high pressure = low pressure

I verified that the clutch is spinning which should mean the compressor is working. I just replaced the compressor also and the symptoms are the same. The AC clutch can - and should spin - but it's the engagement part, the CENTER part spinning that's important. If you weren't getting a pressure dif...

Re: 2002 GMC Envoy AC problems and what Ive tried to fix them

I believe the experts on this board would strongly advise against introducing any type of sealer into your AC system, and I agree. Sealers and other "miracle enhancers" often clog-up components and create additional and costly problems that weren't there before. Cans with the trigger, hos...

Re: 2008 Ford Ranger Plugged Orifice?

Although I'm not "an expert", I would sure want to know the high and the low pressures at about 2000 rpm with compressor engaged. You just bought this - maybe previous owner added sealer, maybe clogged stuff up. If mine, I'd replace the orifice tube and accumulator, and add by weight the c...

Re: Stuck ac line (but not the nut, the junction)

Have you tried to warm the outer fitting with a propane torch? And then maybe try to turn the flexible line's fitting?
