Heater fan stays on

[pete1499]

My heater fan will sometimes stay on when the ignition is off---and kills battery. Any ideas as to why this is happening?

If you turn the HVAC control to OFF, does it still run when the ignition is off? Could be a problem with you ignition. Do you notice any other accessories stayin on after you shut off and remove the key?

I had the ignition in the off position, I tried the aux position, I turned the key and jiggled it etc. ---didn't do any good. I had to disconnect a battery lead. When I took the car to the shop it wouldn't replicate it. I took it home and ....it did it again!!! I haven't been able to get it to do it again.
