We have been trying to trace why the radiator fan, a/c and rear back up lights are not working in my 86 T1 Le Baron.
The owners manuel shows that they are all on the same fuse.
1. First we direct wired the fan and it does work.
2. Then we tested wires to the under hood fan/ac relay on the drivers side and the relay is getting power.
3. We then tested wires from the relay to the under dash fuse box and the fuse is ok and getting power.
4. I went ahead and installed a new fan/ac relay. [and have since learned that if the relay is bad the fan will run and not turn off]
Still the radiator fan, a/c and rear back up lights are not working.
While looking around under the dash - around the fuse box - I found a four wire plug that was not plugged in anywhere. Could this be the problem ??
Any help here will be very much appreciated!
Here is a photo of the 'Mystery Plug' and a photo of my Le Baron:
