Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I've had a series if problems recently. Some seem trivial but I'll detail all just in case they are relevant. First, the car went dead and wouldn't start. We wondered if this was due to having lights left on.. jumped it and all seemed ok. Once in a while we got the problem where the car wouldn't shift up from first gear (automatic). We pulled over, restarted it, and it resumed normal operation. More recently, the headlights both seemed to blow, one after the other, and we replaced them both. All seemed ok. Then another problem with needing a jump start. Noticed the radio now won't turn on. A week or so ago, there were a series of problems together. The windows wouldn't go all the way up without jolting / stopping. The indicators wouldn't work etc. A guy who deals with electrics locally said it may be something to do with the N10. He gave it a wiggle and all seemed ok again. We're starting to notice problems every time it rains though - the BAS lights come on regularly. I now can't start the car. It's raining heavily and a few minutes ago the HORN started to sound. Then it did it again... then it stopped. Going into the car I discovered the horn no longer works. Looked through the fuses and found fuse 40 blown. Replaced it. The rest of the fuses look ok. The modules look seated ok, and dry. The cable leading into the module box looks damp. Horn still doesn't work though. What's worse is the car now won't start - I'm unable to turn the key in the ignition. Emergency lights work. Windows work. Headlights work. What's causing all these issues to pop up? Is the rain in any way related to the problem I'm having now / is there somewhere I need to check for a leak, or am I missing something else? Help please - need to know whats going on and how to fix it.
NOTE: the remote control WILL lock and unlock the doors. The key won't turn though. I've also tried the spare with the same results, though one of the keys was temperamental and didn't seem to unlock the doors until after I'd tried using it in the ignition. That one might just be a bit flat.
The problems first mentioned.. maybe a month or two - the gear shift thing more often recently but perhaps once a week at most.
UPDATE: Just managed to start the car. Left it an hour or so, popped key in and pulled it out fast. Heard a "lock/unlock" sort of clicky noise. Tried the key and it turned this time.
The "Engine" light in the bottom right corner is lit up once I start the engine.
Cars 2001. Seems generally very good condition considering.
No "proper tests" - no. Had the car about 9 months now. Previously had a clean service record and well kept. No problems indicated.

EDIT: Looks like the horn still isn't working. The BAS or ABS light whatever it was isn't on, but the Engine light remains on.
