Intermittent Feature Test

  1. Disconnect 18-pin combination (wiper/washer) switch connector. Move wiper/washer switch lever to INT position. Turn interval knob to FAST position. Connect battery positive lead to terminal No. 16 (Blue/Yellow wire) and negative battery lead to terminal No. 2 (White/Black wire). Connect voltmeter positive lead to terminal No. 7 (Blue/Black wire) and voltmeter negative lead to terminal No. 2 (White/Black wire). See Figure. If battery voltage is present, go to next step. If battery voltage is not present, replace combination (wiper/washer) switch.
  2. Leave battery and voltmeter connected. Using a fused jumper wire, momentarily connect terminal No. 16 (Blue/Yellow wire) to terminal No. 17 (Blue wire). With jumper still connected to terminal No. 16, move jumper from terminal No. 17 to terminal No. 2 (White/Black wire). With interval knob in fast position, voltage should rise from zero volts to battery voltage after about 2 seconds. With interval knob in slow position, voltage should rise from zero volts to battery voltage in about 5-15 seconds. With interval knob not turned (non-variable position), voltage should rise from zero volts to battery voltage in about 2-4 seconds. If voltage is not as specified, replace combination (wiper/washer) switch.
