Unlikely to be a fuse. The windows and seats are all controlled with a module for each. The switches send a request to the module and module powers the feature.
The system uses a Can-Bus to communicate with all other on-board modules. This system must be working correctly for system components to work. A scanner for MB will be needed to check for faults.
You will not find a schematic anywhere unless you have a MBWIS or subscription to StarTek.
Post your problem at www.mercedesshop.com for further help and/or check http://www.iatn.net/shopfinder/ for an independent MB shop near you.
Depending on the remote, there may be a small screw holding it together, or it may just snap together.
If you do not see a screw in the back (usually these are on aftermarket alarms and such), remove the key rink from the remote, Use a small flat-head screwdriver and gently pry the two sides apart. They should pop apart, and you will see the battery. Replace the battery and snap the remote back together (this may take a bit of pressure).
If you have trouble go to the dealer and ask someone in parts, or a service writer to show you how. They should not charge you for showing you how to do it!----------------------------in many cases you will see that still after replacing the battery in the key does not solve the problem.then in the key there is actually a chip.if that chip looses its charge then it needs recharging.the car service center charges $250 for just charging the chip in the key.but a professional locksmith is very helpfull if the chip needs charging ,as he will just charge under $75 for the same purpose which the service center charges $250.the locksmith have all the required programs and software to charge the chips.any of this two options should help you.1)either the battery needs replacement or 2)the chip in the key needs charging.thanks.please do rate the solution.keep updated.thank you for using fixya.
post all things that fail and work both
all maters
engine starts , runs , drives ok ,day or night?
all other electrical things on the car ,as in ALL do in fact work correctly?
or just the RADIO on the car fails.
many cars now the RADIO is part of the CAN , the car Area Network. and if that fails so does the RADIO.
if is in fact a factory RADIO there from MB.
what to do.
well
check all fuses first. never skip the easy first step and a 50cent cure..
next scan the USA? OBD2 scan port, and look for Radio errors
like COMM failures codes.
can I assume this RADIO is not SDAR , satelite radio
if is did you path the subscription bills? $$$$$$
or
the RD is base Radio and both are in fact CAN bus controlled
so yes, it must be scanned first, after fuses
sorry this is no simple 80s radio, not at all
and is antitheft protected too.
i request this post be moved to cars and not computers.
here is more than 1 fuse, the RD shows 2, F1 and F2
my online docs, are not so good, on all MB.
get the car scanned in any shop.
see the DTC error codes. next.
Question edited for a lot more clarity.Question moved to model category.Sometimes they are just on, and sometimes the SRS will flash. Connect to a pro grade scan tool computer and look for the diagnostic trouble codes associated with the fault status.https://www.google.com/search?q=Mercedes+W169+SrS+system+light+on..
Question edited for a lot more clarity, and add maker.
Question moved to maker category.
These are all function of the Body Control Module. You need an auto electrician with a pro grade scan tool computer and access to factory technical bulletins.

No clues in here.
Immobilizers are designed to prevent what you are needing done. There is no easy way around it. Your best bet is to call a lock smith to cut you a new key and program it to work with your vehicle.
'bonnet', a fellow resident from UK, or maybe Australia. :>D
You normally can't disable alarms as there is a computer in-between the switch and the light on the dash. You have to fix the fault, not find a way around the problem.
The easy way is to connect a professional grade scan tool computer, check for codes and read the data that is registering the problem.
Full 'year make model' in all questions please. Some issues are known issues and can be searched.
