2003 gmc yukon driver heated seat will not stay on

2003 gmc yukon with power seats and driver side heated seat will not stay on. Relay comes in then drops out immediately. Pulled seat cushion cover and element looks good, no burn marks. Disconncted wiring from both upper and lower elements and rung out with ohm meter and both appear ok. Tried to isolate driver seat and backrest elements seperately to determine if a short or ground was present on either element. Noticed that if either harnesses is not connect to plug-in, passenger side seat element will not work. Looked at wiring schematic for both driver and passenger seats to determine if there is a common that both seats share so that driver side must be connected for passenger side to work. This vehicle has a memory seat module which appears to control the logic control. Open for suggestions as to why driver seat will not stay on

I have had similar problem, after much power tracing and power bypass the problem was only solved when I cut out the under-seat connector and hard wired it....I suspect the design of the connector and the location is susceptible to corrosion from moisture
hope this helps

SOURCE: my 2006 gmc yukon xl drivers seat will not move

Under the drivers seat at the rear is a black plastic cover. Remove the cover , it is over the main harness to the seat. Unplug the seat harness and inspect the connection. I see alot of these get knocked loose or get corroded. Good Luck.

See GM TSB 05-08-143-001, If you have Adjustable pedals, especially if they don't work with the memeory buttons, but function with thier own buttons. Its the Brake Pedal Position Sensor is shorted and mesing up the seat module which controls the heaters too. My 05 Suburban had the same issue

Heated seat not coming on


Does the passenger seat stay on and heat up? If so the drivers seat heater grid (just the same as an electric blanket) is shorted or open and that causes the system to switch it self off. To replace the heating grid requires the seat cover to be removed and the grid replaced, this is best left to an automotive trim shop, they are cheaper than the dealer in fixing this kind of problem. The part will need to come from the dealer if still available.

How do i let down the rear seats in 2003 gmc yukon xL


FYI- I'm taking a shot at this one based on my 2003 Montana so take it for what it's worth.
My van seats have a very small level on the drivers side of each seat. Pushing the lever down allows the seats to fold down while pulling the lever up allows them to recline. There is also a small ******** the back side of each seat which when pulled allows them to be folded down.
Hopefully your 2003 Yukon seats are similar to my 2003 Montana seats and this will work for you

Driver's side power seat and heat in both seats not working


hello, have someone check all fuses-and plugs for the power seat, they may be a relay for this problem, can call autoparts store and ask about any relays for the heated seats and the power seat, if thats not it you may have to replace, electric motor for seat, sounds like a fuse, the way it all quit working..

On my 2003 yukon I have no heated front seats working and no power seat for the drivers side.


Look in the fuse box on the driver's side of the vehicle on the outboard side of the dash under the triangular cover which snaps off and on. This panel is not visible when the door is closed. If you have your owner's manual, look on page 5-104. This is where the fuses and relay/circuit breaker descriptions, layout, and specifications begin. This section runs to page 5-111.
You are going to check fuse number IGN3, a red plastic, stab-in miniature 10Amp fuse. It has an "S"-shaped element visible through the side of the fuse body. If the element is broken or burned, replace this fuse. DO NOT use a replacement fuse of ANY other rating; use an identical 10Amp fuse ONLY.
You are also going to look for the "Center Instrument Panel Fuse Block," located under the instrument panel, to the left of the steering column. You are going to check the device labeled "30A CB Seat." This is driver and passenger seat module circuit breaker. This circuit breaker is an automatic resetting device, replacement is necessary only if there is no other problem, and it will not reset.
If only the driver seat is affect, the problem is not the CB Seat; check the wire harness and connector under the seat. There is almost no clearance under the seat, and it may needs be removed to check this. There are four 14mm or 15mm bolts, one at each outboard corner of the seat, the front ones under snap-on plastic covers, which anchor the seat to the vehicle. These bolts are installed with an anti-seize anchoring compound which make them difficult to remove, but aside from elbow grease, there is no other trick to removing them.
Good luck, and if I have helped you, please remember to comment/vote.

My power seat stopped working in my 2003 Yukon XL. The heated seats stopped working as well.


Try this remove the ckt breaker for the power seats the ckt breaker is located in the fuse box inside down by the drivers left foot. leave breaker out for about 10 seconds then reinstall it and see if the seat starts moving. If it does there is a reprogram for this and needs to be done by a dealer or someone who has access to be able to reprogram your vech.
several things could cause your heated seats to not work. If the seat and heated seat seat stopped at the same time could be the reprogram could fix it. If the heated seat quit working at a differant time it could be the seat heater element. get a schematic of the heated seat and ohm the wires for the element. If either element tests open then the element will need to be replaced. You might as well replace both of them at the same time since the seat covers have to come off to replace the seat heaters.(back and bottom ) If one element is bad then both heaters quit working.

Drivers side heated seat controls only. When turning on the heated seat controls for either switch on the drivers side all lights flash then turn off instantly. I can hear a relay clicking each time I push...


There is a drivers and passengers door/seat controll module. These have been failing a lot. dealers stock them now. The element in the seat can also be bad. I recommend taking it to the dealer as painfull as that may sound but they will diagnose it properly because they have to command it on and off with a scantool. Sorry for the bad news. The modules aren"t cheap and the element is difficult to replace. It is worth the 80.00 it will cost you to find out. Good luck
