Blower Motor HELP PLEASE!!!

I have a 1993 buicke lesabre with a blower motor from hell. It runs constantly, even when the keys are out of the ignition. I had to go under the hod and unplug the blower motor to stop it from drining my battery. Does anyone have any sugestions? I would also appreciate descriptions or schematics of the blower motor relays and control module.

Blower relay. In the MaxiFuse and Relay Center. Should be labeled as such. If not, pull the out one at at time. When the blower turns off, that's the blower motor relay.

I had the exact same problem with our 1992 Buick Lesabre. I posted exactly how to fix it. In my Thread. But most likely you will have to relpace the blower motor resistor and the blower motor itself. neither of which are cheap brand new. you can get the resistor online for around $100 and a motor at a local parts store for about $60 here is the link to the thread and if that doesnt work search for Heater A/C Malfunction
