And they both react the same way? Or are you only trying the one side?

What about the back?

If they both react the same way its doubtful both are faulty at the same time, although coincidentally, it could happen.
Probably the switch not working right or you are doing something wrong.

Read the manual again to make sure you aren't pressing the back heater, then the back and butt heather or you are pressing it three times and shutting it off and thinkings it not working.

Sorry, just without seeing it personally its hard to figure out whats wrong other than "user error". No offense.

Its either all or none. If they work the front and back work if not none of them do

Then maybe fuse? I'm not sure if they're all on the same fuse. Other than that it could only be an electrical problem in the whole truck.

Not any help but I had the same issue in a Suburban. Never did figure it out but same symptoms. Eventually they worked again without issue. My only guess was that I had either a self curing short or water issue?

when they do work try moving your weight around in the seat or bouncing in the seat, if they shut down you likely have an intermittant open in the seat element which will disable the entire system Scanning for codes would be a big help

Humtech-

My driver side comes on and off intermittently. I've searched and found an so many opinions if I followed them all I'd be replacing the entire driver side seat and wiring harness with module.

Do you have any info on where to start?
