I have a '97 Ford F-150. This morning I went to get in my truck and the fan motor for the heater was running. At first I thought I had left the ignition switch on, but that was not the case. Then I noticed, with the ignition switch on, that the warning light for the airbag was lit up. This warning light goes out when the ignition is off. If I leave the blower on, it runs no matter if the ignition switch is on or not. Anyone run into a problem like this before?

I think they use relays instead of resistors for the control, the high might be stuck on.
