I have a 1977 Cadillac deville that keep blowing the fan motor relay. I was told at the parts store that there was a upgraded cube type relay for this car. I got one and as I have read on your forums it would seam to be straight forward,but I am haveing a little trouble. The way it looks to me by looking on the relay,post 85 and 86 activate the relay and post 30 and 87 or 87a supply the power to the blower motor. I have four wires and what the wiring diagram shows is the wire for the blower is supposed to be hot at all times,and the other wire goes to the programmer, and has no power to it . Then I have a red wire that is hot all the time,and a org/blk wire that goes to the blower controll. What I did was put the wire from the fuse panel (whitch is a brown wire and is only hot when I turn the key on) to post 85and I put the blue wire on post 86 I put the red wire on post30 and the org/blk wire on post 87. The problem is the blower motor runs all the time even if the key is off., I can syre use some help
