Hi folks
New to this forum
I have a 1992 suburban in good condition, 220,000 miles --- still runs good.
All of a sudden the electric driver seat and the electric door locks stopped working. I have checked fuses but can not find one for them. They might be on circuit breakers but I am not sure where that would be.

Also under the drivers seat is some kind of electrical control box about 6 inches by 4 inches --- mounted to the seat bottom. It does not appear to be wired directly to the seat but not sure what it is.

any thoughts and ideas. It is a 2500 series.

I am a reasonably good mechanic --- but can not figure this one out.
