W208 Power Roof Problem

[Izza]

Please help? Power roof won't go down.
The electric head rest up/dwn switch red ligh flashes and they don't work either. The windows go down as if proceedure is starting the roof just sits not doing anything? Ever heard of this could it be the motor is it a coincidence about the head rest? What should I check I dont have a wiring diag or even know ehere the motor / fuse is?
Thanks in advance for any help/pointers

well the headrests have to be down for the hood to go any further. i would start looking at the headrests, then go from there....

I had a similar problem - it turned out to be the interlock switch that is enabled when the 'hood guard' is in position in the boot. The switch had come loose and wasn't making - as far as the car was concerned the guard wasn't in position and therefore the hood wouldn't go down.

It's worth checking - the switch is accessible on the offside rear section of the sliding rail part of the hood guard.

If the switch isn't made, the windows go down and the red light flashes - just like you described!

Hello,

I have the same problem. Fuses are controlled, head rest is in down possition, contact from the roof guard is OK, boot closed: Button flashes red, windows go down but the roof don't move. Anyone who can help me. Thanks.

I had the same problem today and it was the roof guard switch. Suggest you try it with the roof guard unlocked and see if the sequence is the same - windows go down and roof switch flashes red. If it is then the roof guard switch may be faulty. Check boot lid switch is operating as 'boot open' will give the same fault.

I had a problem with my roof, except it was down & wouldn`t close. As you described the headrest light and the roof switch light flashed.
I had to close it manually and then take it to the dealers.
MB were very helpful. I called in on spec, they took it into their workshop there and then & tried to reset the closing sequence but weren`t able to do anything, so I had book it in to the workshop.
Their diagnosis was to replace the "1-2-4-35 fastener" (£198 + VAT) and the "n/stock switch" (£19 + vat) plus labour, total = £445 - no thanks !
Took the car to an independent specialist (ex MB dealer, I believe who lost MB franchise) and the cost to fix it was £121.61. To quote their invoice
"closure confirmation switch S84/13 not working, this subsequently proved due to a leaking joint in the hydraulic unit. Tightened joint, reset parameters, checked roof operation, all now ok"
So, all due to a leaking joint. Worth a look ?
Hope this is of some help.

Many thanks, I tried what topdown suggested but without success. Is there somebody who can tell me where the 1 2 4 3 5 fastener can be found or the n/stock switch.

I hear a light noise from a contacter when I pull the red flashing button so I think there is a problem with that contactor but where can it be found?
