2-Speed System Tests (Intermittent Only)

  1. If wipers run without delay and switch is in delay position check continuity between switch terminal and ground. Constant continuity or constant open, replace gear box assembly.
  2. If wipers will not run with switch in delay position, disconnect connector from intermittent wipe control unit. Place switch in maximum delay and check voltage between positions "4" and "6" in terminal junctions. If voltage reads zero check panel switch and wiring. If reading is 10 to 15 volts replace control unit. If wipers operate, but will not operate after placing switch in delay position, check voltage between positions "4" and "8" and follow same procedures as above. If wipers fail to operate continually when wash control is operated during delay mode, check voltage between positions "4" and "7" and follow same procedures as above.
