I have been trying to figure out how the wiring works for a late model rear defrost and I have way more time in it than should be neccessary. Here is basically my dilema:
I have a Bestop Hard Top on my TJ with defrost. My Tj came with a soft top from the factory and therefore doesn't have the stock switch for a rear defrost.
I got the defrost switch from a 1999 Jeep Cherokee for my TJ. From experimenting with my Dads Xj I figured out that the four wires are for:
Power when Lights are on for illuminating the switch
Ground
Relay (ground)
Power when defrost is on
I wired it all up and it worked, except the timer doesn't. It comes on when I hold the button down only. I thought maybe there is a time somewhere, so I went to Jeep and looked at a harness made by Jeep to add a factory hardtop to a jeep. No timer to be found. I thoguht for sure the timer must be in the switch, now I haven't a clue. I even checked to see if XJ and TJ switches are the same. They are.
Any help would be appreciated. I got a fog light switch and took the cover off and tried to make it work too, but now I can't make that switch work either.
Thanks!
