32	Remove clamping pliers
	Check
33	Check catches on power window (1)	Catches should mesh. Otherwise the power window (1) must be readjusted.
34	Carefully move power window (1) in and out of front door	Power window (1) must not come into contact with window guides. Otherwise the window guide may be damaged. The side window must not retract more than 5 mm into the upper door frame. Otherwise damage may occur. Leave a clearance of approx. 2 mm between power window (1) and brackets for power window (1). Otherwise damage may occur. Leave a clearance of approx. 1 mm between power window (1) and rear armor plate. Otherwise damage may occur.
