Heater stuck on

Hey guys,
Ive started noticing a problem with my car that is becoming more persistant. When I use the heater in my car it turns on fine, but it doesnt like to turn off. It seems completely random as to when it will shut off.
For instance: The heater was turned on full blast to bleed the system the night before MPact. The whole drive down, and back from MPact the heat would not turn off. I drove the car the day after and it was fine. It doesnt matter what I do with any of the dials. It just seems to have a mind of its own once it sticks.... Any ideas?
Thanks
-Tyler

Sounds like your resistor has gone bad. Very simple & inexpensive to replace.

Seems easy enough to replace. It would be this diy correct?

Do you mean the blower sticks on the high speed or do you mean you are actually getting heated air? If it's the blower then Karl's diagnosis is right on. If you can control the fan speed but you can't stop it from being hot air then it's the heater control valve.

Bleh... In that case its the heater control valve..... I think I can deal for now lol. I really dont want to tackle that after I just did all the hoses back there. I should have thought to replace it while I was in there.

If you can catch it when it's not on you can disconnect the electrical connector from it and it might stay turned off.....
