Turn off car air conditioner blower stays on - 2001 Ford Expedition

Sounds like the blower motor is going bad

posible blower resystor and relay is all une piece mounted nes blower motor

Probable cause that the blower motor continues is that the power supply is constant. The only time that the blower motor is off is when you actually turn the heater/Air conditioner switch off. The blower remains on all the time if you are only using the fan controller as this only controls blower speed.

Check to make sure that the controller is working properly. Is this a 2009 Lariat? or a 1997 F150? I have a controller for the 1997,

I'm having the same problem was wondering if you figured it out?

sounds like a loose wire

it is most likely the clutch on your ac compressor has siezed. start the truck.....turn on a/c and look to see if the pulleys are all moving

OK, if the relay for the A/C fan is bad, then the radiator's fan will keep running after turning off the ignition. Also, if the fan for ventilation of the A/C in the cabin stays on after the ignition is turned off, the relay for that is bad.

Good luck on this repair.

Engine fan or cabin blower? Actually either can stay on if relay contacts are burned and sticking. Engine fans sometimes stay on for a few minutes after the car is turned off but should not run for a max of more than three minutes.

This might be the noise problem in your blower.The blower is out of balance with this added weight.

I would use a multimeter and check if the voltage changes at the blower motor, as you turn up the blower speed on the controls. If it goes up, you need a blower motor. If not, the a/c amplifier.
