Warning light comes on for cab roof

I have a C4 cab, the roof warning light comes on when the roof is closed. I understand that there are 2 micro switches which control the system. Does any one know how these are adjusted and if it is likely to be the problem.

Thanks for your help
 
Remove the trim panel that covers the locking motors. You will then have access to the 2 screws which hold the micro-switches in place on either micro switch. Loosen the screws and slide the microswitches forward a bit. Tighten the screws. See if that works - did for me last week. Note however, this light staying on is usually an idication that the roof is closing unevenly which points to one of a few possible problems with the roof. Problems which you should remedy immediately or you may end up with a broken cab-transmission or worse again a broken Top-Bow...

Thanks very much for the reply, it seems you are right, the adjustment did not make any difference, if the roof is closing unevenly how do you idenitfy what the the problem is ? What is a Top -Bow and is there any thing i can check with the cab-transmission.
