DESCRIPTION & OPERATION
A permanent magnet wiper motor is used for low, high or intermittent (delay) wiper functions. There is a base and a high line intermittent delay. Base intermittent (delay) wiper function provides a .5-18 second delay mode. High line speed sensitive intermittent (delay) wiper function has two ranges. At vehicle speeds greater than 10 MPH, delay mode range is .5-18 seconds. At vehicle speeds less than 10 MPH, delay mode doubles to 1-36 seconds.
Base delay function and high line function are 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.
On Durango, rear wiper system is single speed only. Wiper motor has integral electronic control module. Vehicle is equipped with a front and a rear washer system which utilizes the same reservoir. Each system consists of rubber hoses and nozzles, an electric pump, sealed motor, low washer fluid indicator and reservoir.
