So the wife was driving home tonight (I'd had a few drinks) and it was cold outside (40F), so I hit the button to turn on the heated seat and it lit up for 2 seconds, and then went back off. This happened each time I tried to turn it on (on for 2 seconds and off). The air conditioned seats wouldn't come on either. But the heated steering wheel worked just fine as did the heated back seats. Anyone had this happen before? Any ideas? I've never had a problem with them not coming on before.....

 

It looks like fuse M35 in the fuse block is for the heated and cooled seats in the front, and fuse M36 is for the heated rear seats, and the heated steering wheel. See if the fuse is blown.

 

Thanks. Will do.
