Tahoe with no heat!
Hey Guys,
My tahoe is giving me another issue. The heat isn't working in the front, but works fine in the back. They both blow air, but the front is cold and the back is hot. Any ideas? Thanks. Tim

are you talking about the heater core coolant lines? I'll have to try that. How come this stuff doesn't happen in any other season? Cold winter weather isn't my favorite to work in.

what year tahoe? my 03 had an issue where the rear heat, and the passenger side heat were blowing hot, but the drivers side cold, i did some digging around and found that the servo that controls the heat mixing on the drivers side had hung up and did not reset when the truck was started up. try switching the controls to cold, then shut the truck off, wait a minute, start it back up and then switch the controls back to hot. this worked for me. but if you have one of the newer, nicer than my base model, with the digital controls, it might not help.

the reason his heat in the back works is because there are two seperate heater cores one in the front and one in the rear assembly i found both of the cores on line the rear is a little tougher to findbut heres the links for both incase blowing the core out doesnt work
