96 Ford Explorer blower motor doesn't turn off when engine is turned off

Most likely the resistor has shorted to hot. It is close to the blower.

Is it a temperature-controlled fan? I've seen some cars that run their fans for a few minutes after the car is turned-off, to cool-down the engine. After a few minutes, it will automatically shut off -- it also shut-downs when the "target" temperature is reached.

Have you checked to see if the blower relay is stuck on ?

blower motor or resister bad

It's programmed to turn the fans on when you turn off the engine if it senses that the engine is getting overheated.It's normal.----------------------------------------------------------------------------

Have you adjusted the pushrods properly? Pushrods generally need to be adjusted after installation.

Not sure how to do this on this model, although I own a 94 Ford Explorer with the V6 4.0 Liter motor.

Basically, when a gas engine doesn't run, you check 4 things, and narrow it down from there.

1. Gas (Is gas pressure good, is gas flow strong enough?)
2. Spark (are all spark plugs firing properly? Is spark strong enough)
3. Combustion at each cylinder (timing, pushrod adjustment)
4. Air Flow (MAF/MAP sensor working? Air Filter dirty?)

It most likely is the heater control assy. say this a lot when i worked for ford.

go to bottom of arm take end cap off loosen bolt / Turn on wipers Check to here the motor if its running if its running turn off and tighten up the bolt wiper arm at bottom then turn the wipers on if you here the motor running if you do not check fuse under dash and in engine compartment / Please rate my response thank you very much

Basically, you have a fan relay that has shorted and burned. The relay is used because of the different power setting needed for the fan speeds.

Trouble shoot all fuses, incase you blew a fuse when the relay went. The relay burned but that did not effect the motor, thats why the motor runs well.

To find the location of the hi speed fan relay, check with your local parts store to see if they can bring it up on a computer.

I would check to see if there is a short on the fan controller switch and the motor. sounds like a crossed wire, especially if it's ignoring your speed selection and running when the key is out. could be near the fuse box under the dash. the cig lighter circuit is live all the time as well as a couple others, it maybe crossing with it. I would pull the fuse panels assem down and check for crosses and shorts.
