For a while now I’ve been having small issues with my cars electrics, the main interior Dome Light which contains Courtesy and Map lights, the control switches for the sunroof and one of the interior climate control sensors has been causing one or two issues including a power drain which discharges the battery totally if the car has been stood for a couple of days.
I keep the car on a trickle charger when I’m at home which helps a lot.
I took the car in to have the power drain checked and I was told it was the dome light. So I purchased a fully tested second hand replacement and had it fitted, however it made no difference and the power drain has persisted. A few weeks ago I tried another dome light but that too made no difference but when I put my light back in, the courtesy lights didn’t work on both the dome light and the doors and an issue with the sunroof appeared where the roof would only inch open unless it was reset. Then it would work fine for a while before starting to play up again.
And this has continued until last night where things seemed to go very strange indeed.
My car has keyless go but it only works off the drivers door sporadically, mostly on locking but very occasionally on unlocking but over the past week its stopped working again.
I was out in a heavy downpour last night and visited a friend. When I came out the car unlocked on the keyless go and all of the courtesy and door lights came on, much to my amazement. But then when I pulled up at home my headlights refused to switch off! I had to sit for a good ten minutes turning the headlight switch on and off as well as the ignition and eventually they turned off.
When I came to the car this morning I didn’t even try to switch the headlights on but I noticed that the courtesy lights no longer worked and then after arriving at work I was told that the back of the car had dropped on the nearside left by a couple of inches.
I replaced the nearside rear ABC damper last year so I’m not sure if that has failed or this is linked to the electrical issues too.
There are no warning lights on in the car, the ABC lifts and lowers as it should but again the rear nearside left of the car is still sitting lower than the rest.
Is the damper likely to be a separate issue or is all of this potentially linked to the electrical issues?
I have booked my car in with my local Mercedes specialist, but they are incredibly busy and can’t take the car until the 18th July.
I can’t help but think that the electrical issues are something to do with the sunroof allowing moisture to get in to the void where the electrical connections are for the dome light?, but now the damper has dropped I don’t know if they’re linked?
Any tips or guidance would be greatly appreciated.
Many thanks
Kindest regards.
