2010 jeep blower stays running after button off


changing the blower motor was a waste of time and money, you have power going to the blower after the switch (button) is turned off, could be a bad switch

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.

Blower motor won't shut off on a 2005 chevy monte carlo


Your post is not making sense. If the blower motor wasn't shutting off, how would replacing it cause anything to change? Clearly, there is a problem with the power supply TO the motor. If you want the motor to turn off, you need to check WHY the power to the motor is not cut off when the switch is turned to the off position. Probably a bad switch. Or it could be the blower motor resistor even, albeit a lot less likely.

My heater/blower fan will not shut off in my 2005 envoy even after my ignition is turned off and key is out, i've read a few similar problems on this, what is the solution and how much will it cos


Depending which HVAC system you have Manual (sliders for temperature) or Auto (digital readout), the control module is likely at fault. The Manual HVAC has a Resistor Module (which have a high failure rate) and the Auto HVAC uses an electronic module. Both of these are mounted next to the blower motor located behind the glovebox.

Blower motor runs somethimes


Could be a faulty switch, or wire connector problem, and not necessarily the blower motor. You could save yourself $600 by doing a little troubleshooting to find the problem.

Try wiggling the wire connector at the blower and the switch. If it is the blower motor, spend a few dollars for a chilton's manual or haynes, and do it yourself.

most likely you have a very bad ignition switch, the only other pathway for switched acc. to operate when key is off is if someone has had the wires feeding the fuse box crossed. so unless you had recent wiring done by an amature, you need and ignition switch. after replaceing you may still need to replace some fuses or bulbs that didn't like being powered at the wrong time.

I have a 2002 Sonata and the blower doesn't work at all. How can I check whether it's the motor or the switch.


First, I would check the fuse for the blower. If the fuse is good, there should be an electrical connection on the blower itself with two wires, one is the positive feed and the other is the negative. To test the blower, turn it on and see if you are getting power to either one of the wires, you should only get power to the positive feed. If you don't know which one that is, try probing each one with a test light individually. If neither wire has power with the blower switch on, then power is not getting to the motor and it may be the switch. If power is getting to the blower, unless the ground is bad, the blower is your problem. Remember to have the key turned on while performing this test.
