Last weekend I installed a set of leather heated power seats in my H3. The seat heaters aren't working. I have connected all the orange wires to battery power. The brown wires to ignition power. Black to ground. The only unused wires are on the passenger seat a red and a baby blue color wire. The seat belt switches are working fine as well as the power seat motors and Lumbar motors but, not the seat heaters.
Does anyone have a clue how to solve my problem?

 

If you didn't originally have heated seats, there probably isn't a fuse/breaker in the fuse box for that feature. Find the right fuse/breaker slot and add one.

 

I have had to run all new wires to these seats. I didnt find any plugs under the carpet for the added options on these seats. The lumbar option as well as the seat positioning portion work perfectly. The passenger seat airbag on sensor and even the seat belt connection switch works properly only the seat heaters are inop. I guess maybe I need to remove the heater switches and check for power and go from there.
