Question about 2002 GMC Yukon Denali
Last year the rear would work fine and the front would take 20-30 minutes to blow somewhat cool air. This year both systems blow warm air. Fuses are fine pressure is normal and I can hear the clutch engage in compressor.
Need to have a set of gauges on it and read the low side and high side to see if pump is weak that year compressor i think is on the bottom passenger side ,it is not a good desigh pump may be weak
