Wiring for new off,on switch

test the socket

Theres a good chance you have a broken wire or wires in the drivers door wiring where it has to flex. I hope this helps. Take care.

I don't think even a wiring diagram will show the terminal locations. You may have to sort it out from a wiring diagram for the windows for your car. Each window will have it's own color code for up and down. What a nightmare! You could be at it for awhile till you get it right. The lengths and hi-jinks some people will do on their cars! I would find a like car at a junkyard, snip the connector off with just enough wire to show the color (or longer if you just wanna splice it into your wiring), bring it home and match your wiring from it. Probably only a factory service manual would actually show the terminal locations. Good luck, Odel, and you didn't even say what kind of car you had, though it made no difference to me.

Denis use a meter on the switch. Measure resistance / continuity. Find the 4 contacts that are made when the switch is actuated. There are 2 terminals for blue and 2 terminals for brown. The terminals are paired so that each of the 2 terminals is made when the trigger is actuated. Blue to blue... brown to brown and grey will be the last terminal. It will not matter which side of the switch you connect the wires to as long as you pair up the colors. My concern at this point is the gery wire. If it is piggy backed to another terminal and you disconnected it this can be a problem. I believe the grey wire is for actuation of the brake. If this does not help you feel free to seek other experts. I do not think your going to be able to locate a wiring diagram without the aid of the products service center.

I only answered to try and help you due to the fact I know getting the wiring diagram will be a difficult task.

Thanks for choosing FixYa,

If this is the old style limit/fan switch. Turn power off
remove the wires and label where they got disconnected from and wire the new one in. Make note of the settings on the old limit switch so you can
adjust the new one. The limit switches come in
different lengths so get the right one.

If it is a flat bimetal disc, then I think you have only to
wires that have to be connected so hook up same
to wires from the old one. With Bimetal disc fan
limits you need to make sure you get the same
temperature reading as the old one

ON one side of your switch it is connected with a small peice of metal or should be. That is why it only explains 3 wire instead of 4. If you look you can find the one you need with 4 spots to put your wires. Just look or ask your store for what you need. They can be very helpful in helping you find what your looking for. Hope this helps.
