Your vhicle build date is on a blue sticker on the driver door or door frame. If not there, check other doors.
The heated seat Module is under the seat. You can unplug the connector on it or the heated seat switch to shut it off. I supect the module is bad. get one used from car-parts.com.
The cabin air filter is under the leaf screen at the base of the windshield. Remove wiper arms and leaf screen for access.
Please rate, thanks.
Principles of Operation - Heated Seats - Vehicles Built 03/2002 Onward
NOTE: Two heated seat modules are used, one for vehicles built up to 03/2002 and one for vehicles built 03/2002 onward. The modules are not interchangeable.
The driver and passenger heated seats share a common battery and ignition feed. A shared ground source supplies the heated seat control switches. When the heated seat control switch is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. The heated seat module then supplies power to the heating element circuit. The cushion element and seat backrest element are wired in series and powered by the same output. The heated seat module also will ground the separate indicator circuit at the dual automatic temperature control (DATC) module display panel to indicate an ON state. The heated seat module will remain on until the heated seat control switch is pressed and a momentary voltage signal is received, or until 10 minutes expire. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the switch is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.5?C (99.5?F) and maintain the temperature until time-out or switched off. This temperature is maintained by the heated seat module monitoring the temperature sensor located in the seat cushion element, and adjusting the current flow to the heating elements.

i have the exact same problem with my 03. I still cannot find anyone who knows the solution.
I have exactly the same problem!! 03 Suburban.
I have exact same problem. 03 suburban
Yup - same symptom - comes on for a second then turns off. Then LED light on switch comes on for a asplit second only and I hear the click but turns off super fast. Neither seat works when this occurs. Resetting the ignition causes the 1 second on, then off to start over.
have the same problem...2003 suburban
same problem 2003 suburban
Same problem.
samething
Exact same thing on a Tahoe
I have a 2005 Suburban and have the same exact problem, except driver seat last about 30 seconds before it goes out.
Same here but with a 2005 Suburban ?
Same problem, now my driver's side just clicks on and off the whole trip
same thing turns on for 30 seconds, then turns off
When I turn the heated seats on from the buttons on the door the lights come on and then click off a few seconds later. Both driver and passenger side. Checked and changed fuses did not solve the problem
sounds like relay worn out or temperature sensor problem
Same issue 03
