Hi, Im 16 and just bought my first car a 73' 2500. The windows don't work in it but the previous owner showed that you can remove the switches and jump it so im thinking its the switch that's not working. I have looked under every rock on the internet for one of these things but I can't seem to find one for sale. Ill attach photo of it and the plug pattern. I also need a single switch for the passenger side.
