96 C280 - Locking System Problem
 

I've got a 96 C280 and the locks are giving me grief. The nitty-gritty:

The IR remote stopped 'working' (i.e. unlocking the doors), although the red 'indicator' flashes. After resynching according to the procedures outlined in the manual (press button remote twice then turn key to position #2) failed to fix the issue, I replaced the IR remote's batteries and resynched. Still non-op.

Next I checked the fuses - starting w/fuse #23 (the buse box indicates that fure controls the dome light, rear headrest down feature and remote IR system). Fuse was fine. Dome works OK. But, the rear headrests don't fold down when the button is pressed - although there is a clicking sound eminating from back near the headrests. I proceeded to check all the fuses - hood & trunk mounted - and they are all OK. Not sure if the headrests are the same or a different problem.

SO???? What could the problem with the IR remote be if it's not the batteries in the remote nor the fuse?

Thanks for the advice!

Fixed!
 

As crazy as this sounds.... after trying everything else I disconnected the battery for 10 minutes, and whamo - fixed. Not sure what the problem was, but it's better now.

If you've got a similar problem, I'd give the battery trick a shot.

Did you have to synchronize the remote after reconnecting the battery? And do your headrests work now?

Remote & headrests
 

The remote didn't need a resynch, and the headrests are now operational. Go figure. Gremlins I guess. It makes no sense to me, but I suppose I am just happy to have it working again.
