1st cold day put on my heater and NO HEAT !Took it to CHANDLER MB they say I have a bad Heater Control Valve, NOT COVERED under my warranty ! So I am looking at $ 498.00 Installed by the Dealer, they say it's a lot of Labor to put in !

Blower works fine but the heat is not coming on at all. When the engine is warm, it maintains around 190 deg F like it should so it is not the engine thermostat.

Heat quit working in front and back of car
Not sure how long I have had this problem..no one rides in the passenger seat. The heat on the driver side works perfectly fine, however, the heat on the passenger side is blowing cold air only.
