2003 Tahoe, fuse for seat heaters

The seat heaters are coming on (and its 85 degrees plus here) I turn it off but later it may come back on...I thought at least for now I could pull the fuse but I cant find a fuse labeled for the seat heaters.

There is a 30amp circut breaker in the I/P relay block (under the dash, left of the steering column, near the floorboard). That breaker is for the memory seat module, which also controls the heater function. The fuse is in the underhood fuse box, labled MBEC, 50amp fuse. If you pull that you will also lose operation of the r/f door accessories as it supplies power to the r/f door breaker also.

Thank you very much for the information....It seems that for a temp fix the only thing to do is pop the little control panel in the door and unplug the switch until i can find out what to do next. Is it a good possibility that the problem is the switch on the door since the heater can be turned off with the switch when it comes on?
