I cant get the friggin blower motor to stop unless battery is disconnected. someone recommended a relay may be stuck. I do not know where that relay is. It isnt in the relay box under the hood or on the fuse panel. This 1988 $2100 eldorado is upsetting me with the little bugs and now tranny problems but i need to be able to no have to disconnect the battery each time I shut off the car. PLEASE HELP
