    Why don't you just disconnect the seat heater grid in the seat for now?

2006 Yukon Denali XL the radio stays on as well as the battery symbol on the dash and the dash lights and the heated seats buttons also light up with the car off and locked keys out of ignition


Yes that's normal. it should go off as soon as you open the door though. if it doesn't then they will go off when timer expires (normally about 90 seconds) after you leave the car.

The heated seats on my 2004 Yukon Denali keeps shutting off on my front seats what could be the problem


I would check the wire harness under the seat and make sure they are clear of the seat tracks. Next make sure the plug ins under the seat are tight. If only the driver seat is shutting off may be heat element has gone bad.If both are doing it(passenger and driver) there is probably a module that controls them and that has gone bad.

I have a 04 yukon both front heated seats come on for 10-30 sec than go off both started at the same time so i dont think its in the seats its self (HEATING WIRES) any help would be great


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 messing up the seat module which controls the heaters too. My 05 Suburban had the same issue. Can check by unplugging sensor and see if heated seats work .

02 GMC Denali front heated seats won't work


test to see if you have any power going through all the connectors for the seat heater, there may be a spot where there is a connector that has gone bad, or potentially it could be the whole element that is bad
