The blower fan for the heatAC on your Intrigue comes on by itself when the car is off What is the cause of this?
If your blower motor is either not turning itself off, or
randomly turning itself on with the ignition off (and you have auto
climate control), the problem is the blower control module. Located
directly behind the blower motor, it takes information from the
climate control, and is in charge of turning the blower on/off.
To replace the blower control module, remove the splash shield
under the passenger side dash (there's 3 plastic retainers hold it
in place). The blower control module is located behind the blower
motor, and is held in with 3 bolts. The 2 rearmost bolts (by the
firewall) only need to be loosened, and the front one removed. The
entire unit rotates down and can then be replaced.
