1999 ACCESSORIES & EQUIPMENT
CHRY - Wiper/Washer Systems
Ram Pickup
DESCRIPTION & OPERATION
A permanent magnet wiper motor is used for low, high or
intermittent (delay) wiper functions. Base intermittent (delay) wiper
function provides a .5-18 second delay mode. On high-line models,
delay function is speed sensitive. At vehicle speeds greater than 10
MPH, delay mode range is 1/2-18 seconds. At vehicle speeds less than
10 MPH, delay mode doubles to 1-36 seconds.
Delay function is controlled by Central Timer Module (CTM),
located under passenger side of instrument panel, outboard of glove
box. CTM switches an intermittent wiper relay, located in Power
Distribution Center (PDC). On high line models, CTM is connected to
Chrysler Collision Detection (CCD) data bus network to receive vehicle
speed information for delay function.
Washer system consists of rubber hoses and nozzles, an
electric pump, sealed motor, low washer fluid indicator (if equipped)
and reservoir.
ADJUSTMENTS
WIPER BLADES
With wiper arms removed, cycle wiper motor into PARK
position. Mount arms on pivot shafts, and ensure distances are as
specified. See Fig. 1. Operate wiper blades, and check whether they
return to proper position. If wiper blades do not return to this
position, check linkage and pivot assembly for wear and binding.
