No Delay In Pulse Mode

  1. Disconnect wiper switch 48-pin Black connector. See Figure . Turn wiper switch to LO position. Using a DVOM, measure resistance between wiper switch connector terminals No. E4 (Yellow wire) and E5 (Brown wire). See Figure . If resistance is 600-750 ohms, go to next step. If resistance is not 600-750 ohms, replace wiper switch.
  2. With DVOM still connected, move wiper switch from LO position through all delay positions one step at a time to maximum delay position. If resistance is within 10 percent of 30 k/ohms, 68 k/ohms, 150 k/ohms, 240 k/ohms and 430 k/ohms respectively, repair open circuit in Brown wire or Yellow wire between wiper switch and wiper motor. If wires are okay, replace wiper motor. If resistance is not as specified, replace wiper switch.
