Please help! My 1999 slk230's top won't come down. the trunk lid will open but the motors/pumps just hum. Stealer diagnosed it as faulty switches in the windshield pillar and would charge $900.00 to replace 2 of them. I am wondering if anyone knows if the alternate method of raising the top mechanically will work in reverse? In other words, does anyone know whether or not I can release the locks with the hex wrench in the access in the roof, which would then allow the rest of the hydraulics to work? I tried turning the little hex nut counterclockwise but couldn't seem to get it to go and was hesitant to be too aggressive. Any thoughts welcome

 

Dealer is 99.9% correct.

You can buy switches inc loom att from dealers. Bugger to reroute cables. You can also cut wires near sw and replace .
Simplist thing to try 1st is to remove the silicon bellows off switches as they hold sw open and were changed on later ones.

Bazzle, how do I even get to the switches with the top immobile?

 

Undo white plug in roof, use allen key from tool box and release catches.
