2015 GMC Sierra Lower Seat Heater Not Working (Both Sides)


Recommended Posts

I have a 2015 GMC Sierra 1500 SLT with heated seats ONLY, not cooled. The seat back heaters work really well on both sides on the passenger and driver seat, but the seat portion does not heat on either sides. The button lights up like it's turned on, but doesn't heat up.

 

When I remote start the seat back won't heat up either, even though in the InteliLink the option is set to turn on seat heaters when remote started. Why wouldn't they turn on the steering wheel heat with the remote start too?

 

Has anyone found any solutions for this?

 

When I would remote start my 07 it would turn the seat heaters on and blast the defroster on high heat. From what I understand, the newer generation doesn't do this? It has be turned on before you shut it off? I liked the earlier function where it would turn it high heat and then when the key was turned on it would go back to where it was set when shut off. Seems like we may be going backwards here on the technology.....

I have heated and cooled seats in my '14 Silverado. I rarely use the heated seats and personally don't care for the feel of the cool function. I turned both seats on to heat both seats and backs and found the drivers side back only worked, and not the seat bottom, and only the bottom worked on the passenger side. I took it in and they promptly replaced heating elements and wow, they heat up great now! That is the first problem with the truck since new in Nov. '13.
