Here is a picture from Prospero's Garage of the Fresh Air Fan Relay. The problem is, it does not say where the wire goes off to. Looked at the Fan switch wiring but all wires there are accounted for. Checked original manual and it says wire #14 but that does not make sense, or does it? Where does that wire go, what pulls in that relay?

Hi Mike, that diagram is very helpful. The one I have is cut into smaller pages and harder to follow. There are 2 fans, one is the heater fan that you mentioned and the other is the fresh air relay. It looks like power from the ignition switch goes to terminal #86 to pull in the coil for the fresh air relay. That would answer my original question of where wire number 14 goes (goes to ignition switch). When you turn on the car it allows the fresh air relay to turn on but then the 3 position fresh air switch runs the speed of the motor.
When I turn on my motor to high speed it smells like it is burning and drops the battery voltage down to 10.1 volts. I found the fresh air motor and it looks like it is going to suck to get to. It may not be the motor, it may be the wire connections that go into the motor. They looked cracked and brittle. Just another shitty little project to add to my to do list. Thanks so much for the help. I knew someone or more would come through for me. Now it all makes sense. (IMG:style_emoticons/default/piratenanner.gif) |
