If it shut off after a few minutes it may be running hot. You may need to flush and fill your coolant system and or replace your thermostat.

SOURCE: Antenna motor runs while the radio is on or off. The antenna is stuck in the extended position. When the car is shut off the antenna motor continues to run to retract the antenna, but it doesn't go

You need to pull the fuse for the antenna or just unplug it. It has a fairly ridgid plastic wire that pushes the antenna up and down. Works fine until the wire breaks then it rolls up (antenna down) but it never increases resistance because the antenna never comes down , it's like a fishing reel when the lure breaks off, so the motor thinks that the antenna is still coming down and it will run and run and run trying to do it's job. Your lucky it stuck up and not down. If you want your antenna to go up and down again you'll have to buy and install a new one.

SOURCE: electric fan continues to run even when car is off

OK, This should get you started on the problem. You need to remove the Fuse first to stop it running. Locate the fan switch and check that it is not permanently on (Short Circiut). If it is, Fit a new switch.
If not, then you need to locate the Fan Relay Switch and see if this is stuck on.
Thats assuming you do not have a short circiut in the wiring loom.

You can drive without the fan but not in slow traffic, you must have airflow across the radiator to avoid damaged. Do not allow the car to overheat.

SOURCE: cooling fan running after engine shuts off

Someone hard wired it directly to a constant power source. I assume there was a problem with the fan at one point for someone to do this. If you disconnect the power wire to the fan and jump it to one of the fuses that only has power when the vehicle is running you will solve your problem. I would think your battery would be dying running for over an hour after the car is off.

Fans wont shut off when ignition is off 99 prelude

Some cars are designed to allow the fans to run even with the key off until the engine and radiator cool down. If it continues to run after 19-15 minutes you may have a sticking fan relay, usually located in the fuse box in the engine compartment, just replace it and it should take care of your problem

Sounds like your fan relay is stuck. Look in the engine area for your fuse box, there will be a list for the relays inside. Try pulling the one for the fan. Fans are powered all the time not just ignition on

Car keeps running after key is removed. Taking out ignition fuse shuts off engine.

This sounds like the ignition switch is sticking/hanging & allowing the engine to continue to run. When you put the fuse back in, do the ignition lights come on, if so, then that should definitly be the problem.

You can try to wiggle the key from on to off several times when you shut it off to do further testing & you may see that it will shut off that way. More proof it's the switch.

My 2005 mazda mpv's fan does not shut off after the ignition is turned off. I must turn the ignition back to the starting position and then off again or the fan will continue to run for several minutes...

I have a 2003 MPV with the same problem. There was a recall in 2004 to replace the fan controller module, which apparently would fail regularly. I had mine replaced under the recall although there were no symptoms at the time. Now it appear that the replacement has failed, but I've already used the recall and you can only do it once. Even though your warranty is up the recall still applies if your car is of the model that qualifies. Call your dealer, and he can tell you if you are eligible. It is almost certainly the problem. I don't care how you drive or what the temperature is, your fan shouldn't run immediately after starting or run for more than a couple of minutes after you shut it off.
