My 400E (124 034) has interesting fan problem. If the car has been sitting overnight the fan works fine the first time I start it the next morning. Once the fan is turned off it refuses to come back on. When the fan works the cooling, heating and air distribution system works great, so I'm hoping that it's something with the control switch.

Any insights on anything regarding this problem would be greatly appreciated. I really like my 400E (the wolf in sheeps clothing) with 115,000 miles and with the exception of this problem it's flawless.

Thanks,
