Check fuses, is passenger seat also power operated? If so, does it still function good?

Yes the power adjustments work on the passenger side but the heat does not, on the drivers side both heat and power adjustments don't work. It all quite at the same time. I'm guessing it's a fuse but the owners manual isn't clear on which fuse supplies power to these applications and I don't understand why the power adjustments work on the passenger side only.

Check the fuse labeled IGN 3 (10 amp) in the instrument panel fuse block (left side of instrument panel behind the access panel). Let me know how it tests out and do the power seats have the memory or non-memory style?

IGN 3 tested ok and it does have the memory style seats. The indicator lights do not come on at all when the button is pushed.

Okay, seems this is a common problem with the newer Tahoes. There is actually a TSB (techincal service bulletin) about this issue. Most likely the driver door module will need reprogrammed, however, you need to have the driver door module scanned by Chevrolet dealer to see if it has to be completely replaced or if it just needs reprogrammed.

The driver's side seat heater stopped working. You press the button and it will shut off after about 2 seconds. The passenger side seat heater works perfectly unless the driver's side button is pressed. What do I do to fix this? I don't know what's wrong.

2003 Chevy Tahoe, 42k 5.3L

The heated seat on the driver side recently quit working. When the buttons are pressed on the door, the lights come on momentarily then there's a click from a black box under the seat and it shuts off. I also noticed that the passenger seat works, til you press the driver side and everything shuts off. Does have something to do with the 'black box' under the driver's seat. What is the box called? Is this common? Any and all info would be greatly appreciated!

Thanks!

The Lock, window, and heated seat won't work on the front passenger side only. Could it be a fuse issue? If so, I looked for the fuse and could not find it. Thanks

Remove the window switch on the passenger side and disconnect it for 30 sec. If everything starts working, that unit (passenger side door module) will need to be replaced. If not it will need to be reprogramed

I have a 1999 Tahoe with 98,000 KM on the clock.
The drivers side seat heater no longer functions in either med or high. The passenger side still works, the fuses and the switch check out OK. The seatbelt warning still works as do all the power movement switches.
Does anyone know how the safety cutoff works? Is it a "squat" switch that detects weight in the seat or off the seatbelt warning.
In 1999 the switch for the seat heat is on the lower outboard side of the seat, not in the door as with newer models.
Any ideas??

I have the same problem with mine. Last year at about 75,000 my driver side heated seat stopped working, all other power seat and lumbar swithches work perfect. My passenger side heater works fine too. Ive checked the fuses and they all seem fine. Ive read where this has been a problem in other Tahoe's. Any suggestions or fixes?

My heated seat has failed. Before completely failing it did seem to get very hot when used (even on low) and then just quit working.

I was hoping that you could provide some repair information in your reply, such as: can it be repaired and how difficult or does the seat need to be replaced? If it needs to be repaired in shop, what an estimate might be?

Again, thanks for the help and thanks in advance for any additional information you may be able to provide.

The heating elements usually burn apart and cause them to quit working.

Remove the seat from the vehicle. Remove the seat covers. You will find the heating elements attached to the cushion or the cover. Leave them there. Cut the wires from the heating elements. Attach the new elements to the old ones and connect the wires. Re-install the covers and the seat.

If the switch light comes on then goes off after some time, chances are the switch itself is bad and can't handle the electrical draw. Have that checked to confirm.

Let me know what you find.
