My '01 Tahoe's front a/c system works fairly well while driving but starts to heat up at idle or parked. The rear a/c blows out hot air no matter what the settings are on whether it be the front controls or the rear controls. To my knowledge there is only one spot in the engine compartment that the 134-a is added to and it is fully charged. I also noticed that when the a/c stops working when parked the pressure coming off the same port is through the roof (between 150 and 160). what could be the cause of this and how can it be resolved. Any help in this matter would be greatly appreciated. Thank you all.
