My heat has not worked for several months now, but with cold weather coming I need to get it fixed. A/C works fine for cooling when weather is hot. I recently had a new water pump and t-stat installed as part of a non-related repair, but no-heat problem was not solved. Operating temps seem to be within normal parameters. Water supply line to heater core is very hot, return line is ice cold. Possible plugged inlet to heater core? Seems possible, but not probable. Somebody suggested that I look at the actuator(???). Any other suggestions? |

Replying to: jlflemmons (Aug 01, 2007 8:16 pm) Thanks for the great tip! I recently replace my battery on my '04. Well, when heater is turn on the passenger side blows Hot air but, the driver side blows Cold air; "very cold". I called the dealer and they didn't have a clue but wanted to keep my GMC for a few days. I think your reprogramming will reset the system. . .thanks --Los Angeles, CA

Replying to: lpfeifer (Dec 18, 2007 7:34 am) ok this morning it was cool 45degrees and it took awhile to come on. now it's 65 and it will turn on real quick... if it's 100 the a/c will take awhile to blow but rear air is normal in all aspects
