Hi, this is my first post:
I am computer engineer in traning, and I have a very basic question regrading circuits:
the circuit For the interior car heater looks like the following

and my question is this that this car hearter's fan quit after about 5 minutes of testing it. and I want to fix it, but I am not sure how to go about doing that?
any help is appericiated

Although it is probably not worth fixing, he could:
-check to make sure that it isn't the thermostat simply switching off the unit when it reaches the set temperature.
-check to make sure that the unit isn't overheating (tripping the motor's thermal protection switch). But it is a bit of a weird circuit in that if the heater element is cooking the motor, then switching off the air flow isn't likely to improve the situation...
Since they're only $15 - $20, I'd get a new one (or do without).
