The two way switch only works one way. The other way does nothing at all. Press the same side of switch again and it closes and slides. Press again and it slide closed but does not stop at the closed position. Have to guess when to take finger off switch in order to close it fully without rain coming in !
How do I access module/motor ?
Is there any fuses or relays to check ?
I have a multimeter. What do I check ?
I have been out in the car today. Tried the sunroof. Would you believe it... it all worked as it should! Even though it hasn't worked for 3 months !
So I am going to leave it for a while. If the fault returns I shall try checking the connections you suggest. I know dodgy earth connections can cause intermittent faults. Can you tell me where these earth connections get their earth from ? i.e where do the earth wires connect to the car body?
