So on my C43, the moon/sun roof glass is not working properly, the glass closes when I want to open up (Push in switch upwards), but when I want to close it (push in switch forward) in does not work, but when I put it in in open (pull switch towards the back) it does so for a sec and then stops I have do this like 6 times to open it, but when I decide to close, it won't work, but when I want the glass to close, I push it to open upwards like a wind-deflector, it will do so, but I can never get it to close properly with out pushing the switch many times and vice verse. What can cause this? can it be a relay switch for the roof glass, cause the door windows work properly without problems. Maybe switch or motor are bad??? Any help greatly appreciated.

You have to reset the switch. I don't remember the procedure exactly, but the general jist of it is to hold the switch all the way forward for ten seconds. You probably need to have the key switch in a certain position, so play around with that.

+1,

When the glass closed, press the bottom in close direction and hold it for 10 seconds,

then do the same procedures for rest bottom directions...

ZAYED,,

Hahaha...This problem eluded me when I first bought the car as well! Both ECT and cm60k are correct. Reset the switch as described. Afterwards, when you close the sunroof, keep the button depressed for at least 1-2 secs. after it closes. This will ensure that the sunroof is sealed shut. It should operate normally after that.

Same goes for when you use the "vent" position, keep the switch engaged for a second or two after it opens to complete the circuit.
