Boy have I stepped in it. I purchased a pair of power window regulators and installed them in my car, fit great by the way, but I couldn't get them to work and found out the motors were reverse polarity. I have the original wiring for power windows in my car and new switches I purchased, that fit my wiring but turns out I needed another pole for a ground loop which I know nothing about. Is there a way I can adapt my switches and wiring to this problem, or am I doomed to order the companies wiring and switches, I do not want to rewire my car.

Depending on the signals you are getting from the switches, you may need to add 2 relays at each window motor.

Here is a diagram for a positive signal to operate a reverse polarity motor:

There are also other relay diagrams on "the12V.com" which may be of use.

Just to make sure we are all speaking the same language here.....
Are you saying that each motor has only two wires coming out if it (or two insulated terminals on the motor case) and that you have to reverse the polarity on those two wires (or terminals) in order to reverse the direction of rotation?

If the above is NOT what you have, please describe the motor connections in more detail. Or better yet, post a diagram if you have one.

The motors have two insulated terminals coming out of the bottom. No wires.

That answers the question then. Unfortunately, you are going to need either two relays per motor or else some special switches, like momentary contact DPDT center off.

The diagram that came up was for power door locks, would it be the same for the power window switches?

The link does show a door lock actuator but it has a motor in it just like an electric window and the information will work using reverse polarity power windows.

Here are some more diagrams with window motors used instead of door lock actuator motors:

Jim, thank you so much. I have some relays coming from ebay so that I will be able to get this wired. Your help sure made it look easy for me. I am the worlds worst electrician, I printed the diagrams and should be able to wire my windows. thanks again

Here at Nu-Relics power windows we deal with this all the time. We have a special type of relay that has 8 poles and is designed to reverse the polarity between your factory switch and the new motors. We sell them with a pigtail so its easy to tie into the existing wiring harness. Takes one relay per window motor.

Nu-Relics, if I am unable to wire this relay combo that Jim turned me onto, I will probably have to buy yours. The difference in price from me doing my own and yours is quite a bit. Your customer service representative Darlene Cornelius, was very helpful to me in this regard.I appreciate her help, thanks her for me.

Hopefully you ordered ones that are a good quality. Through the years I have used ones from Tyco, Potter Brumfield, and Bosch and not ever had one fail BUT I have put in no name ones supplied by customer's and had a high percentage of failures with them.

Just a buyer beware warning.

Sometimes having a kit from companies to address certain wiring needs can make things simpler and what you might spend more on initially might be saved with a quicker and more reliable installation.
