Hi can any body throw some light on why my sons e220(1996) should suddenly start playing up,central looking not working,engine not starting,this only happened after the heavy rain 2 weeks ago,he as brought a new key from M B ,(9/10 months ago) he also as a new battery on the car(2 weeks old,just before the rain storm)the motor would not start even by trying to jump start it from another vehicle, I do not know if this as any thing to do with any thing, but the heater fan/blower cuts in/out intermittently, sorry to be so long winded,but trying to give as munch info as possible,sir2u:-(

I had wierd electrical probs on C class turned out to be a failing alternator!!!

If theres a faint glow of a battery light with the engine running then thats the prob, other than that open the fuse box if wet get it dry because thats the problem.

Hi,
Is the engine turning over fast enough?
Have you got red/green LED's on the door/Rear view mirror?
Are the LED's flashing?
Have you tried the spare key?
I,m thinking you have immobiliser problems and the engine starting fault is unrelated to the other electrical problems you have mentioned.
I have cured my immobiliser problems 99% of the time by replacing the fob batteries. The fob may open the car but this does not mean the batteries are ok, as the alarm and locking are two different systems.

thank you guys, the fuse box is definitely dry, the key fob batteries fine, checked by local MB dealer, another new battery fitted (to the car)today, car started no trouble, where do we go from (new battery every month,or what) thanks again,sir2u.
