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
The column mounted wiper control stalk switch on vehicles with rain sensing installed, has an AUTO position (this replaces
the first intermitte nt setting on non rain-sensing wiper controls), five intermittent settings, and normal, high speed and flick
wipe positions.
