Wiper Has "Lo" Speed Only

NOTE: For this test, wipers must operate correctly in delay mode and also shut "OFF" correctly.

Remove connector from No. 1, 2, and 3 terminals and remove No. 3 lead from connector. Turn ignition "ON" and dash switch to "HI". If wiper has "HI" speed, check for ground between No. 3 terminal and dash switch. If no ground exists, replace dash switch. If wiper still has only "LO" speed, remove motor and check for ground in shunt field.
