heat in rear area
2003 Tahoe has rear heat and air option. Blows cold in the rear but no heat after Controls set to max heat after car is warmed up. Any ideas? Blower is fine. Ice cold when set to AC. Just no heat. Thanks.

is the coolant full or any system repairs done recently? does the temp change at all when you switch the hot/cold setting? Have you felt the lines going to the rear heater core? they should both be warm but one would be hotter

I will pull off the interior cover and check the hoses. Was not sure if it just blew air from the front core or had its own. Thanks. Probably a valve not opening as the front works great and the coolant is up to spec.
