Thanks! I think that's it. My windows weren't working, so I swapped H and I, and my seats stopped working.

Also, my aux fan continues to run, and I pulled C or D, forget which one, and the fan stopped.

So I have some bad relays. the car sat for almost two years. Don;t let your car sit for two years, it's not a good thing to do. Everything wokred on this car before I stopped using it. Now I am chasing electrical gremlins.

Another question. Just to the left of these relays are two larger relay black boxes. Below the adjacent black box is a little plug in device that has a diode or resistor in it. What is that for?
