This morning was a cooler morning and I decided to switch on my seat warmer. When I did I heard a pop and my switch went limp. Not clicky clicky is you know what I mean. So I need a new switch. However this is after market and was in my jeep when purchased. I don't know what brand or anything and the only switches I can find online are 3 prong switches. Mines a 4 prong 3 position switch. A high, low and off setting. How can I find out where to get a replacement switch. Didn't think this would be hard to find. But it sure seems to be.

 

The front of my switch looks like that as well, just a generic Amazon kit. I did find the switch velour and it looks to have 3 switch positions plus a ground. Is it possible to probe your wires and see what's what?

I know that the pin running horizontal of the others is the ground. However the switch you've shown has the 3 pin connections and a ground running out where my 4th pin connection is. If you can understand all that. I might have worded it badly. Anyways. I don't know that it would work because all 4 wires run from the pins into a harness connection.

 

For the price I would give it a go myself. I would just connect the harness ground wire to the ground wire on the new switch. In the meantime I would move the passenger seat switch over to the driver seat since that gets used more.
