Wipers and Washers - Wipers and Washers
Description and Operation
Windshield Wiper
The single wiper system is driven via a sh ort linkage, by an electric motor installed in (external on later models) a moulded
plastic weatherproof housing o ff the plenum wet area. The motor and housing are secured to the BIW bulkhead by three
bolts at the top and three screws (two on later models) with locking clips at the bottom. The complete assembly is handed
for left or right hand drive installation.
The windshield wiper is operated via the RH control column stalk switch. Operating modes are normal, high speed, flick wipe
and six settings of intermittent operation with delays ranging from 2 to 20 seconds.
Windshield Washer
The windshield washer is of wiper arm mounted running jet configuration. The je t assembly comprises two conventional
nozzles plus four nozzles of silicone rubbe r 'duckbill' design. If the system is initially operated at low ambient temperatures ,
the 'duckbill' nozzles permit an y frozen residual washer fluid to be ejected un der pump pressure. The washer jet feed tube
supplied assembled to the wiper ar m, fits at its lower end onto a central connector on the pl enum cover. Washer fluid is
conveyed by a rubber tube, from the washer pump to the jet assembly via a manifold on the underside of the plenum cover.
The windshield washer pump is installed on the rear face of the washer fluid reservoir. The 6.3 liter washer reservoir is
installed on the RH side of th e vehicle in a cavity formed by the front bu mper, the front wheel arch liner and the brake

Roof Opening Panel - Roof Opening Panel
Description and Operation
General Description
The steel sliding roof panel which is externally painted to ma tch the vehicle and internally trimmed to match the headlining,
is of electrically operated tilt and slide design. Driven by a single electric motor via a cable and lever mechanism, the slidi ng
roof panel is operated via a switch on the roof console and controlled by the sliding roof control module (SRCM).
Both the electric motor and SRCM are mounted on an extens ion of the sliding roof panel frame and are accessed by
removing the roof console.
Operation
The sliding roof panel is a multi-feature unit providing tilt, one touch slide opening and closing, and slide position selectio n
on opening and closing. Additi onally, on operation of the vehicle automatic locking system with the roof panel open, an
input from the security and lockin g module will close it. On slide opening of the roof panel, a wind deflector elevates at the
aperture leading edge. In the event of electrical failure, the sliding roof can be manually operated by removing the roof
console and using a key or wide bladed scre wdriver in the slot in the motor spindle.
• NOTE: Following manual operation of the sliding roof panel, the motor drive must be re-engaged by manually turning the
spindle 1/4 turn counter-clockwise if the panel is open or clockwise if the panel is closed.
