First thing I'd do is make sure your coolant level at radiator is up to proper level.Your auxiliary heat/cool unit should be in behind the right rear interior panel . (passenger side) If you remove that panel & check the hoses or lines going into it, they should be warm/hot to touch when heat on & engine warmed up to operating temperature. If not, it's most likely a problem with the electronic control, not allowing coolant flow to it, and I'm almost sure that the control cannot be fixed, but needs to be replaced. Triple check all your fuses for heater controls etc, but if everything else is working except the heat part, I'm guessing control at dash needs replacement.

Rear heater working ok , but front heater blows cold ?


Best case is you accidentally left the AC switch on... Check for pinched/bent hoses near firewall of passenger side. Worst case is the heater core is clogged. In this case someone can backflush the heater core to clear it. Good luck!

Hi Jason.
Sounds like you are on the right track with the flow of hot coolant not stopping. Check your heater control valve to make sure it is stopping the flow of coolant through the rear heater core. Let me know. Hope this helps.
