Normally if you blower will not shut off, you have a bad resistor or relay...most likely the relay...
BAD FUSE SOUNDS NUTS BUT IT IS?
Climate control blower motor was the fix. The part cost 441 dollars.
The most common problem when a car's heater fan doesn't shut off when the car is shut off is that the resistor on the blower motor has gone bad. The fuse that powers the resistor should also be checked.
If the fan runs with the HVAC panel shut off, the blower resistor power module has failed.
Have your blower motor resistor or blower motor checked out
when my car did this it was a blown fuse
The blower control module is defective.
faulty blower module. Under hood not far from blower motor
Ifit has the c68 option (auto air) check the blower control module under the hood
The blower on a 2002 Nissan Pathfinder won't turn off if the switch is stuck in the on position or the relay is defective. Removing the blower fuse will cause the fan to turn off.
Blower resistor has failed. It is located behind the glove box.
Open hood . Disconnect blower module located near blower fan. Disconnect, if blower shuts off, repalce module
miller central air fan on outside wont shut off
Has the car got climate control ?
Probably the control unit mounted underneath the relays by the firewall. Get a used one somewhere, but get a new blower (parts store item) to go with it. That might save you from having to buy an other controller.
You may want to check the heater blower resistor, its behind the glove compartment
Look at the passenger side under the hood. The circular tube like thing is the blower. Unplug the wire from the blower to stop the motor. This will stop the motor, however, will not solve the problem. You may have to check the motor relays.
check the headlight/multifunction switch
are you sure you're not stupid?
it needs a blower motor control module located under the glove box
the air wont run if engine is shut off. u need engine running to operate the compressor. i would check the rear air blower. sounds like the blower switch is not working or there is a short in blower motor get it checked before it causes a fire in vehicle . try removing rear blower fuse and see it that stops it it is a good place to start looking for the problem
why wont the ac compressor shut off stays on on all settings
That's called dieseling, and the main thing that causes it is improper ignition timing.
Your thermostat might be shorted out. Remove one of the wires off of the stat to see if the furnace will shut down that way.
on a 1990 cadallic sedan de ville after you cut the car off the blower keeps running killing the battery
