Seat Heater
#16
I have had a similar problem for quite some time. Lately, I am on a good streak, so my diagnosis efforts have been put on hold.
JDAVE and OBP: when you two have "failure" are you referring to just "no heat at seat," or are you also saying that the light on the rotary switch is not working.

Thanks a lot for your posts; awesome to have such quick and helpful replies! In my case, the heat seater switch lights work always; but, the seat never gets warm. It only worked the other day this week for the first time since my dash removal airbag fix in June 2014.
I was driving to the dealer to have them replace the seat heat controller which they had decided was the problem when I tried OBP's headlight switch maneuver. Within about 30 seconds, the seat began fully heating bottom and back. The dealer had checked everything earlier this week from the fuse, to the switch, and they determined all were getting power but the controller was not passing that power on; as I posted earlier, they replaced the controller and it did not solve the problem.
Has this happened to either of you guys or anyone else, after having the dash removed for the airbag recall? Mine worked fine until that was done.
thanks again!

Never had the airbag recall done cos I am a 2005. I have had both rotary switch light failure as well as a working rotary switch light but no heat. Seems like I had no trouble today when I took the car out with a friend. Both sides were good.

Perhaps OBP can update how many times this maneuver has worked for him.
My car is a 2002 with 56K miles by the way.
Thanks,

I think I left the headlight at "off" for a bit but obviously the next time I drove at night, I switched it back to auto.

Drivers heater stays on while driving
Suddenly my driver seat heater stays on even though I do not have it turned on. I pulled fuse 23 in passenger fuse box. Seems like that solved the seat portion but not the upper back. I live in Florida so I don’t even need this feature. Anyone else experience this weird happening? Please help!

I was able to get the full thread. Since I am a Moderator, I can access. Dave is looking into the details of the attachment, he wants to make sure the original owner agreed to share this post/attachment. Let's wait.
