1999 E320

[joshwht54321]

I have a couple of problems with my 320 and I was wondering if anyone could help. The FSS warning Service now wont reset per the owners manual instructions. And when I push the power window button all the way down the windows dont go up or down. Its in the possition where you should be able to let off of the button and the widows will go up or down by themselvs. Thanks

Hi Josh and welcome to the forum.

The window thing sounds like they need to be re-synched/calibrated such as after a battery change. The exact procedure is in your owners' manual.

The FSS won't reset unless you're close to a change. For example if you try to change it when it's 6,000 out it won't go.

You can force it by disconnecting the battery for a time and then reconnecting. Then you get to resynch the windows, etc. again.

FWIW some of these odd electrical bugaboos show up when a battery is getting old and weak. If that might describe yours a change may restore everything for you.

Take care and enjoy the ride,
Greg

The FSS will reset at any time AFAIK. Get in and close the door. Follow the directions in the manual. I've done mine a number of times and I still need the manual in front of me and usually it still takes a few tries to get it to reset. I almost always reset my trip meter too because I haven't followed the directions exactly.
