Depending on the make model and year, there may be a blower relay that has stuck on. You should be able to unplug the relay, or the blower fuse until you can get it checked out.

SOURCE: Blower stays on when ignition is turned of.

The sensor is probably defective as it keeps the fan on regardless of water temp. Get it replaced.

SOURCE: Blower motor will not shut off. 2005 Buick LaCrosse

There is a bulletin for this fix.The bulletin number is 05-01-39-001A.This pertains to the blower motor staying on after key is shut off.What you will have to do is replace the blower motor resistor module and install a capacitor in the wiring.Part number is 25073556 for the capacitor.The blower motor is on the right side under the dash.Just remove the insulator panel and you should be able to see it if you look up into the dash.Or turn it on and listen for the blower motor.Disconnect the connector to the blower motor control module.Find cavity a and c.Cavity a is negative and cavity c is positive.C is red and A is black.Splice the positive lead of the capacitor to the red wire and the negative to the black wire.You should use splice sleeves and solder the wire on.Hope this helps.Good luck.

2000 venture blower motor won't shut off with the ignition


Could be something in the key switch I suppose. There is a high speed relay for the blower that gets power directly from the battery, but the other speeds should go thru the fan switch and get power from the key switch.

If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.

Blower motor will not shut off


I can't speak to the cost, a local dealer can do that. As for the reason the fan runs on, it sounds like either a stuck power relay (location should be in the owners manual) or a bad fan speed regulator. Since the fan is stuck on high, I suspect the fan speed regulator is bad. On some cars the regulator is part of the fan assembly, and on some it's separate. Also, there is a possibility you can repair the circuit board, assuming it's something as simple as a burnt out diode. Best of luck!

Its your blower motor resistor.Its either bad connection or faulty resistor.Its located on passenger side near floor mounted on heat duct.Wiggle the connector with your ignition and fan switches on it should start working.

The a/c is not blowing out any air at all. it was working great when we stopped & turned off the ignition. when we started it up it will not do a thing . defrost, or heat won't work either.


That sounds like a bad blower motor to me. Try this: Remove the lower panel from under the right side of the dash. Turn your blower motor on HIGH. Look up under the dash behind the glove box and find your blower motor housing. Take your fist and "thump" on the blower motor housing. If the blower starts blowing, replace your blower motor.
