HEATER

Toyota Corolla

: (
My 97 Corolla has no heat. Replaced the heater valve didn't fix the problem. A/C working fine so the air blown ok. Just no hot air? Seem like the cooling not flowing thru the hose cuz at the engine's end of the hose is very hot but not at the control valve's end? The thermostat maybe? Please help.
Thanks.

Dear Corolla,
Sounds like either the thermostat was removed and never replaced(are you the original owner) or struck open. See if the car is reaching normal operating temperature by checking the coolant gauge. If the car is running at normal temp. The thermostat is working which means the heater core is clogged. Remove the heater hoses and run water through one end of the heater core with a garden hose and see if it is clogged. If so flush same and it should fix your problem.
