Intermittent Wiper Speed Circuit
- Turn ignition off. Using an ohmmeter, measure resistance between terminals No. 14 and 15 while turning intermittent wiper switch. Reading should be zero ohms with switch in the "S" position and approximately one k/ohm in the "L" position.
- If reading is correct, replace time control unit. If reading is not correct, check wiring harness continuity between TCU and intermittent wiper switch.
