Cause	Remedy
Front window switch group failure.	1 Remove, replace and install center console switch group
	Model 163.113/136/154/172/174 up to 31.8.01	AR72.29-P-0001GH
	Model 163.113/154/174 as of 1.9.01 163.128/175	AR72.29-P-0001GI
	For left front window switch failure: ↓ 2 Remove fuse f30 from fuse and relay box F1 (MY '98, '99) or F2 (MY '00, '01)
	For right front window switch failure: ↓ 3 Remove fuse f29 from fuse and relay box F1 (MY '98, '99) or F2 (MY '00, '01)
	4 Connect digital multi-meter to quiescent current test adapter then install adapter into relevant removed fuse position
	Digital multi-meter must be rated for a minimum of 20 ampere current draw.
		Fig 1
	5 Monitor amperage draw while operating the appropriate window switch to fully lower and then raise the window Disregard blocked current which occurs momentarily once window reaches fully raised or lowered position.
	If window operation current exceeds 12 amperes: ↓ 6 Determine cause and correct as necessary For example: Distorted window frame, rough window regulator operation, etc.
	The observed maximum operating currents (raising and lowering) MUST be included in the dealer text field of the warranty claim.
