QuestionQUESTION: I have a 2002 300M. The car has been relatively trouble free. Today my wife & I went shopping and she told me that her seat heater was broke. (It would not come on) I tried mine and it would not come on either. I had used mine last night. My first thought was that it is a fuse. I looked in the manual and could not find a listing for the seat heaters. I looked on both panels and can not find any fuse for the seat heaters. Can you give me any insight on this problem?
ANSWER: Hi Jeff,
That heated seat control fuse is #14 in the fuse box behind the dash. That is needed to operate the seat heater electronic controls, but the actual power for the heaters proper is circuit breaker No. 2 nearby to the fuse array in the same box, so try re-setting that breaker.

QUESTION: Thanks for the info on the fuse. I marked it in my manual. Where exactly is the circuit breaker and how does one reset it? The fuses are numbered in the box and on the cover, but I did not see anything else listed as 1, 2, etc.
The heaters actually started to work again after one day of not using them. I did remove a number of fuses and did some tapping on the under hood module. I may have reset a breaker without realizing it. Thanks for your help. Maybe you can give me some advice on my door lock/unlock system. It does not work with the key fob units. I had them tested and they are working but they do not operate the locks. I can save that for a later time. (hasn't worked for months) The seats were more important> Thanks again.

AnswerThe two circuit breakers are right next to the fuse array, the natural color 8-pin plug and the low beam headlamp relay. 1 is close to plug, 2 is close to the relay. The breakers are like small light switches make the #2 look the same as #1 by flipping the switch if it is different looking. Probably it is ok because these don't reset by themselves! but you will know where it is for future reference.
It may be a gremlin that has gone away, I hope.
Thanks for nomination, and by the 'rules' you are entitled to consider and award me another nomination based upon this answer.
