Re: My R4 compressor never cycles, either
Adjustable cycling switches haven't been used for over 30 years---Everything used on GM vehicles are non-adjustable--(no screw between terminals). Cycling switches are there to avert freeze-up and low refrigerant charge (pressure) ruining your compressor. If it is not cycling- it's most likely the ...

Re: 1995 Buick Skylark evap leak?
'95 "N" car evaps aren't too bad- I've done a dozen or so. The drain pan comes down, the heater core is removed and the evap comes out, there are about 13 5.5mm screws (brass-colored) that need to be removed- most mechanics only put about 8 of them back in- thats how I tell if evap has been replaced ...

Re: 78 Trans Am R12 System Rebuild, High Port Adaptor
The reason they say don't use high side is so you don't try to charge through it with pump running....Duh. they are playing it safe.
Those threads on the port you want to use are easily recognized as metric 134a threads- the same that are on a 30 lb tank of 134a refigerant. So your new muffler is ...

Re: 99 suburban dual air issues
Most common issue when replacing multiple parts on a dual system suburban is that the OEM orifice tube is on liquid line from condenser out to right in front of "Y" to rear system. Here is where the problem occurs-- Most all new condenser purchased will have a brand new orifice tube in the line out ...

Re: 2007 Yukon Denali – no air flow – freezing but not low on charge?
Low side pressure switch on your accumulator is bad-- it should cycle off the compressor at about 22 psi and back on at about 28 psi or so. I am concerned of lack of oil return when you run below 10-15 psi. I used to test continuous run (stuck shut cycling switches) compressors- and the front ...

Re: 02 Silverado ac compressor problem
I agree- next time "clutch stops working" get out of the truck and find a way to bump the front hub (clutch) of the compressor- chances are really good it will snap in and start working. This is a sure sign of a "too wide air gap"- Fix it by removing the clutch, and removing the thickest shim in ...
