Fuse Location For Power Seats?

mcstore · November 14, 2007

I have a 2004 (early 2003 1/2 type) 2500HD crew cab, LT, Duramax. Both power seats have stopped working I have check all the fuses under the drivers side panel & under the hood drivers side with a test light. Do you know if this is on one of the larger breaker style. Also both passenger windows are in-op I can hear the rear passenger click. Driver side windows work fine. I also have tried all door switches and drivers door switch to open them. Last I have just noticed my right brake light is not working but I think I can figure this one out on my own. Any info would be helpful on the seats & window problem!

edit.. I have just also found out the Diag connector will not read any codes is this also on a fuse maybe it is related?!? I have tried two code readers one snap on and the other not sure what brand both say can not connect.

Okay I figured it out... The passanger side windows & power seats are on 2 relays 25amp and 30amp under the dash left side off steering, these relay's get power from a 50amp fuse block under the hood. This 50amp fuse was blown causing only the right side windows not to work as well as the power seats! Also found all 4 turn signal marker lights #194 to be burned up as well as the taillight. I just turned 100,000 miles and it has been trouble free until today! Maybe the 50amp fuse block blows @ 100,000 miles as some type of warning. LOL, no really I was kidding about that! Hope this may help someone else!
