    I have the same problem. Car is off. The A/C is not on; this is winter driving. The only way to turn off the blower is to pull the fuse.

    1997 buick regal--found battery dead after a day of heavy rain. Hooked up to jumpstart and interior fan started immediately (with key out of ignition). Car finally started and runs fine, with exception of blower on high at all times and must disconnect battery to stop blower (I need to verify I pulled the correct fuses, which did not stop blower.) This is interior blower (for heater/AC), not radiator fan.

    I have this same problem, it just started about 2 weeks ago. I have a 2001 PT Cruiser which I am the original and only owner of this car. The problem is when the car is shut off the blower keeps running and will keep running till the battery is dead. I have to make sure the blower is in the off position when I park the car, otherwise a jump will be needed. Any suggestions? etellier

    Are you refering to the cooling fan for the radiator?

    If so it runs off the temperature of the coolant and will run for a short time after the car is turned off, normaly 1-2 minutes at most.

The problem is a bad fan relay - it needs to be replaced. I had this same problem, researched it, found the solution, replaced the relay and the problem was solved. If you are not familair with cars - you may need to take it to a shop to replace the relay. The relay is not usually placed with the other relays since it needs cooling - often mounted to a frame member.

That is normal but should stop after engine temp drops down.

With it still running with the key out of the ignition the first thing I would do is swap out the ignition first since I have known a couple of people with the same problem and this is what helped them.

Blower only runs on high

Ignition switch is the culprit. On Fords for high speed blower motor is direct whereas the lower speeds go through the ignition switch. If there is an issue with the switch the blower will only work at high speed. A schematic will confirm that.
