Definitive answer on adjusting the micro switch
Folke,
I recently had to replace the entire lift assembly or regulator on the drivers door on my Spyder. I talked to a member of the SE Maserati club, Kai and he volunteered to help. As we were taking the door panel off another member, actually the president of TMC - Mike showed up so I just let the two take over. Bottom line the regulator I had was shot and needed to be replaced. Bought one from Eurospares (see post:
http://www.maseratilife.com/forums/showthread.php?t=4800) and installed it no problem. It worked but the window pop down to door open position wasn't exactly correct. I got back in touch with Kai and he got some info about the main micro switch. After removing the door panel, the switch lies behind a piece of tape over a round hole in almost the exact center of the door. You'll probably need to experiment a bit by watching the switch riding on the cam as the window goes up and down to resolve your problem but in my case the cam had to be raised up as far as possible and pushed towards the front as far as possible.
N.B.
1. When removing the door panel it would help to keep the screws in order so that they can be replaced exactly.
2. The door trim cast aluminum strip, or sometimes in carbon-fiber, needs to be replaced by putting some pressure on the middle of the strip so that both ends can be inserted and pressed into place before snapping the 2 middle tabs. If you start at one end and work towards the other you'll not be able to get the last tab inserted.
3. There are 3 clips along the top of the door that hold the interior weather strip as well as the panel itself to the door.These clips need to be on the door with the weather strip installed before pressing the panel back into position.
Hope this helps.
