Wipers Start to Wipe, Stops Before One Complete Cycle, No Park

1. Verify that motor will park when the column switch is put in the OFF position.
2. Set wiper control switch to maximum DELAY and allow motor to run until it stops during the wipe cycle. When motor stops, disconnect 25-way blue connector from the body controller.
3. Connect positive lead of voltmeter to pin 20 of blue connector and negative lead to the metal case of the body controller.
a. If voltmeter reads 0, check wiring for an open circuit.
b. If voltmeter reads 10 to 15 volts, proceed to step 4.
4. Using an ohmmeter or continuity tester;
a. Check for continuity between pins 20 and 24 of blue connector of the body controller.
b. Reverse ohmmeter leads on pins 20 and 24, again checking for continuity.
c. If continuity between pins 20 and 24 is not observed in both steps a and b, replace the body controller.
