16	Install power window (1) with front bracket (toward A-pillar)
17	Install rear bracket (toward B-pillar) for power window (1)
18	Replace screw plug for hydraulic liquid reservoir with bleed screw	when replacing power window (1). If the screw plug on the hydraulic liquid reservoir is not replaced, leakage can occur and the system can fail.
19	Install hydraulic fluid reservoir on front door
20	Install hydraulic unit on front door and connect
21	Connect CAN box (as control unit replaced) or control unit with power window control unit on power window (1)

23	Fit the nuts (4)	Toward the inside there should be distance of 5 mm between the power window (1) and the door liner and at least 3 mm between the window and door paneling (armor plate). Otherwise the power window (1) can be damaged.
24	Carefully lift power (1) until power window (1) makes contact with the bottom edge of the side window	When lifting power window (1), ensure that the threaded pins of the side window and the holes in the power window (1) coincide.
25	Carefully screw on nuts (4) until marking (arrow A) is reached
26	Center power window (1) on side window (see arrow B and C; refer to Fig 1)	Center power window (1) in relation to side window. Otherwise the window guides can be damaged.
27	Fit the nuts (3)
28	Tighten nuts (4)	Nut, window lifter to front door	*BA72.10-P-1018-01Y

30	Tighten nuts (3)	Nut, side window to window lifter	*BA72.10-P-1006-01Y
31	Remove clamping pliers	Clamping pliers	Fig 2
	Check
32	Check catches on power window (1)	Catches should mesh. Otherwise the power window (1) must be readjusted.
33	Carefully extend and retract power window in front door	Power window should (1) not come into contact with window guides. Otherwise the window guide can be damaged. The side window should not reach into the upper door frame more than 5 mm. Otherwise damage may occur. A play of approx. 2 mm should be present between the power window (1) and the brackets for the power window (1). Otherwise damage may occur. A play of approx. 1 mm should be preset between the power window (1) and the rear armor plate. Otherwise damage may occur.
34	Check whether ball joints are seated correctly in the brackets of the power window (1)	Ball joints should not make contact with power window. Noises can otherwise occur.
35	Release pressure in pressure reservoir for hydraulic power window in front door	It is necessary to relieve the pressure in th pressure reservoir of the hydraulic window lifter in the front door. Otherwise the hydraulic line couplings can no longer be connected.	AR72.10-P-1800-06LFS
36	Remove hydraulic liquid reservoir and hydraulic unit from front door
	Install
37	Install door module on left and right front door		AR72.10-P-0900LFS
