Stranded without wipers in Chicago as we speak - here's what happened:

1999 C280

Has had intermittent "window inoperative" issues - that always clear up when I remove the negative battery cable for a couple of minutes - they just start working again

Today, during a misty salty Chicago weather pattern - I had to do that again,

NOW MY WINDSHIELD WIPERS, WINDOWS, SUNROOF AND ELECTRIC PORTION OF THE LOCKING SYSTEM ARE INOPERATIVE

AND WORST OF ALL - THE TRUNK IS STUCK SHUT AS THE LOCK ON THIS MODEL IS 100% REMOTE OPERATED, EVEN THE BLADE KEY ONLY OPERATES A SWITCH


Thus, I'm locked out of the trunk and that is where the bulk of the engine/chassis control fuses and the battery are.

Current status is as follows:

Car runs fine
Car starts fine
Voltage at underhood junction point is 13.2
Heater, AC, defrost OK
Windows inoperative
Door locking system inoperative
Sunroof inoperative
Remote control door locking/trunk inoperative

I need HELP

1. How to access trunk if necessary to effect repairs

2. What the hell just happened? Main control computer? (I'm a parts broker so it won't kill me to replace one......or two "black boxes")



HELP HELP HELP CANT DRIVE WITHOUT WIPERS IN CHICAGOLAND IN WINTER

 

I don't know specifically what's wrong, but you sound desperate and no one else has answered, so here are some suggestions:

-you may be able to fix it just by having the dealer reset your computer for the various functions. Perhaps the computer has been tweaked by all the battery terminal removals.

-you should google "trunk open mercedes" and "mercedes trunk won't open", and you will get *many* sites to read, and certainly some may help you enter your trunk at a minimum.

-to get into the trunk, you might try seeing if your back seat will fold down (or come out) by looking for a release mechanism. See one of the posts on this page for example:
http://www.benzworld.org/forums/w208...wont-open.html
Once you can enter the trunk, there may be tab or something you can pull to manually open the trunk from the inside. It is a safety mechanism on many, if not all, cars these days for people shut in car trunks.

-or as a very last resort, remove the back seat; it probably unscrews.
