Huston we have a problem. I need to know were the wires go for the blower relay in a 70 oldsmobile 98. Done all the checking I can have a shop manual and a complete wiring digram. But as they are connected with a molded plug all of those cheat sheets don't show what wire goes were only what they do. So if some one has access to a 70 with the comfortron system can you look under the hood on the left side of the fire wall down low close to the head is the relay in question. It has 4 wires one big is power the other is blower one small is ground the other the trip. Just tell what colored wire gos on which peg. Some enterprising person has cut the plug off this one. Then wired the blower to a toggal switch on the dash. My guess is the relay is shot i have another, just not the knowledge of were the wires go.
