My wife has a 04 Tahoe Z71. We're having a problem with the seat heater. When the button is pressed to turn it on, It turns off immediatly. A click is heard when this happens. Can someone here please help? She wants to drive my suburban because I have heated seats and you know we can't have that. That's why I got her own truck for her to drive.

 

Maybe the click is a resettable circuit breaker. If so, then there might be a short in the seat heater.

 

i was thinking a short too...

 

Did you ever diagnose the problem, My wife's 2003 LT is doing the same thing. When I turn it on it shuts off after about 30 seconds, I tried the passenger and seemed to stay on til I turned on the Drivers side then they both shut off.

 

anyone ever solve this? my sister has an 04 z71 with the exact same issue. heated seat will turn on for the driver side for 30 seconds and then shut off.

73 have you seen any resolution to this issue? i know you are on this forum almost daily.

 

No but original answer in post #2 is all I can offer. Maybe some type of thermal overload protector.

 

My 2005 z71 suburban seats come on when not asked to. Not good in the summer. I also heard the licking sound as it turn on and off. What I did was disconnect the battery for an hour. Sometimes this will reset the computer inside. I thinks the Suburban has 3 computers in it. It did come on again and I did the same thing with the battery. I had to do this 3 times before it went away. That was during the summer. It has not happen since. Easy fix if it works.
