2001 GMC Yukon XL 1500 SLE 5.3L Pressure
Posted to GM HVAC on 7/27/2005 8 Replies

Hi everyone..We have a 2001 Yukon that the a/c works great on for an hour or so..Then with no warning, the high side goes to almost 450 psi and the low side to 90 psi..Engine not running hot, driving down the road the pressures do not drop..I'm suspecting this...
