Six problems related to air conditioner have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
A/c is running ok then, it starts blowing warm air. Outside temp display drops quickly until it reaches +28 deg. F. (note that outside temp is +85 deg. F. ) outside temp display starts rising slowly. When crosses +30 deg. F, a/c starts blowing cold air again. Outside temp display then sticks at +50 deg. F and does not go any higher.
A/c initially operates normally. Outside temp display then begins decreasing. When displayed temp passes +25 deg. F, a/c no longer produces cold air. Outside temp display continues dropping to -34 deg. F. After ~5 minutes, outside temp display starts rising. When temp display passes +25 deg. F, a/c starts producing cold air again. Outside temp display reaches correct outside temp. Occurs intermittently (I. E. , once or twice a day -- or not).
2002 Trailblazer has air conditioner problems. This is the third time this problem surface. It would produce hot air when the outside air temp is @mid 80's and the vents are producing extremely hot air when the temp selected (auto) to 74 and this time the driver air works fine but extremely hot air is coming out of the passenger side. Does not matter what settings are selected. Dealership states that this is a recurring problem with the Trailblazer air conditioner. Something with the sensor.
Consumer states the air conditioning system has failed on several occasions.
Doors rattled and physically moved up and down when driving over bumps in the roadway. A/c does not cool properly after stopping and starting again. Wind noise around driver and passenger front windows. Front windshield molding came loose while driving.
While driving brake light illuminated the dash. Once brake light illuminated, air conditioner shorted out. Contacted dealer. Problem has not been resolved. Please provide any further information, and vehicle identification number.
