Question about 2004 Chevrolet Suburban

2 Answers

My 2004 Z71 Suburban rear air blowzs warm sometimes. It starts out cold then all of a sudden it blows warm/hot. We turn off the rear air for a couple of minutes and then back on, it will blow cold again then blow warm after a few more minutes. We've noticed that while it's blowing cold air it will blow warm then cold for a second on and off then all of a sudden warm steady. Any help or ideas would be appreciated! Thanks! Glenn

I don't believe this was his problem. I have the same issue: hot air blows on the drive side sporadically. It's got to be a sensor or electrical issue, maybe a contact. The passenger side remains ice cold and so does the back. If I turn the car off, then on again, it usually works correctly again. I've also thought there might be a correlation with removing the dash cover just a bit and putting it back in place seems to solve the issue (again, making me think it's a contact somewhere or a temperature probe).

Any ideas? Someone's got to know the schematics.

Sounds like you have a leak in the system and have air that has entered into the system.
best to have it serviced by a shop, the system will need to be inspected to find the leak and then evacuated. part replaced and refilled.
leak detector will be okay

Do NOT use the cans of refrigerant with sealer in it.
and do not let the shop put a sealer in it, in the long run this will cost you the replacement of the whole a/c system.

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

1999 Suburban, A/C on warm air from front vents, cold air in rear


The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

Heat blowing cold air in 2004 chevrolet suburban


With coolant full and engine hot,make sure both heater hoses are hot. If not replace thermostat. If they are, check the blend door for proper operation. Otherwise you may have a bad climate control module. Check both front & rear units.
