heater in car keeps blowing after car has been turned off?

Year/make/model, please.

you need to make certain precisely what's occurring. There are some issues that artwork at the same time for the warmth to function interior the 1st place. warm water has to offer warmth. Air has to go in the time of the heater to pass the warmth to the cabin or the motor vehicle. There must be a thank you to handle the place and how plenty heated air gets in. There in simple terms is not any warmth without warm water circulating with the aid of your heater middle, that's a small radiator that can provide the warmth for the heater. some have a valve that controls the water pass to the heater middle, some have an air door that controls the air pass with the aid of it. possibly some have the two, i don't recognize. while you're turning out to be to be warmth once you do not choose it, then even though blocks the warmth isn't doing it is interest, the two as a results of fact it has develop into blocked or caught open, or perhaps though controls it has a reason that it is not working. some controls are mechanical, and could artwork whether there is not any ability. you could hear air doors beginning and closing if each little thing is off and you progression the controls. some are vacuum operated, and easily artwork if there is vacuum attainable to function the doors or valves. in simple terms after shutting off the engine, you could hear hissing and air doors shifting some situations after shifting heater controls. some are electrically operated, and could not do something till the secret's on, and a few won't do something till the engine is working. With the engine off, and the significant on, you could tell if the fan will turn off thoroughly, or if it consistently runs (some do run each and all of the time, for ventilation). Many automobiles have a number of of fan velocity positions that supply up working. If all else fails, you could open the window and permit some warmth out.
