The common problem for the climate control fan not going off after the engine has stopped is the fan relay sticking. Replace the cooling relay located in the engine compartment near the fan housing. Usually if you tap it with a hammer it will go off. This is the fort sign its the relay sticking.
No it wont. The heater core is just a small radiator inside the cabin that when the fan is turned on heats the air. A bad heater core will cause you to have no heat inside or will leak coolant on the carpet.
Check the fuses.
When the engine is turned off, the car heater can still work by using the remaining heat stored in the engine and circulating it through the car's heating system. This allows the heater to continue providing warmth inside the car even when the engine is not running.
well for one is your keyed turned all the way off. But i would say you probably have a short in you wiring somewhere. But try turning off the heater while the car is running then shut your car off.
igination on car is turned off but car still runs
Open hood . Disconnect blower module located near blower fan. Disconnect, if blower shuts off, repalce module
It is possible that a car can smell like gas when the heater is turned on for a few reasons. One possible reason that this happens could be a leak in the line.
most likely you need to replace te heater core.generally i if the leak is on engine you wont smell it in the car
car start and drives fine bu when its turned off it wont start until it cools?
The motor which blows air through the vents.
solenoid or relay switch
This is actually common for most cars. The reason is that the heater pulls heat away from the engine into the car itself.
