1999 Chevrolet Silverado 1500 Q&A
1999 Chevrolet Silverado 1500 Question: a/c blowing hot air
A/C is blowing hot. Have narrowed it down to temperature control. Compressor working. Lines are cold. Seems like the temperature control knob on the dash does not cause any difference in the air temperature coming out of the vents. What should I check now? Thank you! - Visitor
The temperature door actuator behind the dash may have failed. If so a fault code should be stored in the a/c control module. Reading, diagnosing , and repairing the cause of any stored fault codes should get your a/c system back to proper operation.

Truck just started blowing hot air through the driver vents while the cold air blows through passenger vents when the a/c is on. Why?
