Hey everyone, been having some issues with my 2003 H2 drivers seat and heaters.

A few months ago, the heaters on both sides became erratic, and both front seat heaters quit working, the rears still work.

There would be a clicking sound when the buttons were pressed, but they wouldn't stay on.

now, the drivers seat is inoperative, no forward and back, no rear seat back, no lumbar, the passenger seat still moves back and forth etc.

I checked the fuses in all three spots, pulled them and replaced them, no change.

I looked under the drivers seat and there is a ton of stuff that all looks ok with visual inspection, but not sure what to check first.

there is a big module under there that I assume is the memory and probably the heater relays etc.

Anyone have any ideas, thanks?

 

I think there was a TSB about a wiring harness getting chaffed under the dash near the emergency brake pedal bracket but that would blow the fuse. Did you try the wiggle test?

 

Mine did the same thing and I found that I was stepping on the fuse panel with my left foot and caused a bad pin connection. Take it apart and look closely at the pins.

There is also a breaker in the fuse panel.
