Attempted to fix the errant passenger heated seat today. As the story goes, there was a wire unplugged on the passenger harness (see attached).
The normal function of the rocker switch for heat is to illuminate brighter on the selected setting. When it's depressed now, the selected setting goes out. Fine, because the wire is unplugged.
Plug in the wire. Try out the seat. After about 5 minutes, it dawns on me that the rocker switch didn't illuminate brighter but had same behavior. Psycologically I thought it was heating. I had the drivers side on as well, and didn't notice for a while that it ALSO turned off. Great both seats not working.
I unplug the wire and noticed that lumbar support didn't work on the driver side any more either.
Check the fuses... drivers side heat gone (under hood), lumbar support blown (under rear seat). For the heck of it, I replaced the passenger side adjustment fuse (under rear seat) as well. Everything worked fine except my radio had lost all presets AND the in-dash OBC display program was erased!
There is definitely a short somewhere (that's why the wire must have been unplugged in the first place!) and I believe it's not worth the trouble to track down, unless someone has an inspiration :|
On a side note, one of the lic plate lights blew during that time as well but I believe it's not related :)
I guess the primary point is that after plugging in the wire on the passenger side, the driver side heat/lumbar blew. BOTH seat adjustments still worked (forward/back, tilt).
