Power Seats and Windows Died

Asked by Apr 07, 2011 at 03:27 PM about the Chevrolet Silverado 2500HD

Question type: Maintenance & Repair

Power seats and both passenger side power windows suddenly stopped working. I
found some circuit breakers for them, but I find it hard to believe that they both
would stop working at the same time. That being said, they ARE right nest to each
other in a panel under the instrument panel.

I cannot locate which fuse powers either one of them :(

Any help would be GREATLY appreciated!

Have a GREAT day !

There are fuseable links on all cars, they are another form of a fuse. The fusible links are a special kind of wire that also works like a fuseand will burn thru if there is a problem that the circut breakers can't handle. On your vehicle they should be on the staterbattery cable. They look like wires on the big terminal of the starter. Lightly pull on these wires one at a time(they should not strech) if the fuse link is blown the wire will strech like a rubber band. If you find that a fuse link has melted inside be carful you have a big electrical short and maybe you should seek a professianal.

The fuse you are looking for is located in the engine compartment, center left (driver's side). remove the square (approximately 8" by 8") black plastic cover to expose the fuses. The fuse that controls both the windows and the seats is the 50 amp square fuse at top center (top is @ engine side, bottom is @ fender). You will no doubt notice that the fuse element has burned out by looking thru the clear plastic window on the top of the fuse and comparing with the 30 amp fuses to the right of this fuse. If your windows are operating, but your seats are not, your 30 amp rectangular aluminum covered fuse under the instrument console left of the steering column needs to be replaced (remove the fuse block cover by unscrewing the plastic hex bolt in the center of the cover and releasing the plastic overlap catches on either side of the cover). Fuse layout legends are printed on the inside of all fuse box covers.

Hi guys I have a 2002 Chevy silverado 2500 HD 4X4 fully loaded. Both front heated and power seats don't work. The 25A circuit breaker in the side of the dash gets hot real quick as soon as I plug it in. The SEO2 fues under the hood is also for the seats. As soon as I put a brand new fuse in the SEO2 spot it blows. I really need some help here. Seats went out when my wife was driving and she is 5'4" so the seat is all the way up. I'm 6'1" so it is very uncomfortable. Please any help would be much appreciated.

I have a 2005 GMC 1500. I had the same problem with my windows. I replaced the rocker type switch in the driver door. I agree that the GMC electrical schematic shows a 25 amp circuit breaker that is non existent for the 2 door truck. The GMC factory does not have the proper schematic and refers you to the dealer-----bogus!

Mikemoran: You may have a shorted power wire supplying the power seats and heaters....likely on the Driver's side. Locate the Driver's side seat and heater power cord harness connector under the Driver's seat, The harness will disappear under the carpet toward the accelerator & brake pedals. It will reappear from under the carpet somewhere by the firewall under the steering wheel. Likely under the carpet near the firewall, the Driver's foot has been pressing this harness against a sharp edge of metal under the carpet and felt padding, cutting into the harness and shorting the power to ground. This would cause your fuse to blow. The fix is to locate & inspect the damage to the harness wires & use electrical tape to re-insulate them from the sharp metal and each other. You can file down the sharp edge on the metal and/or just tape a couple stout pieces of cardboard over the sharp edges to prevent occurrence. (For cardboard, I suggest 3 layers of the 12-pack carton cardboard of that beer you bought to celebrate fixing the problem!). If you don't find the problem on the Driver's side, then check under front passenger's side carpet. Please post back here if this was the problem and/or how you resolved this mystery!

Mikemoran: I agree with Steven on this one 100% Happened with my 01 silverado and like he stated driver side under the carpet. Mine was in line with the parking brake pedal where my heel hits when pressing the brake down and rests while driving. My solution though was cutting all 4 wires (they should be a thicker guage #12 yellow wires) bout half way down where it runs covered in that driver door floor step panel deal, extending the wire and rerouting it with the other cables like its going ip to the dash and then butt splicing again up high under the steering column. If you just want to tap them back together just make sure to just rest rip and tap. You wanna get rid of all the wire that insulation is melted too, feels stiff, or has blackened.

Hey guys. Sorry to jump in on this thread a little late. I found the issue to my problem. I had every same symptom that mikeyroman had. I looked under the seat. turns out the 2 plugs for the power seats are identical. the difference is in the details. follow the colors. the black, orange and one other color i cant recall at this time needs to match up with the female end. it was a matter of switching the wires.
