1	Did you perform the Wiper/Washer Diagnostic System Check?	Go to Step 2	Go to Diagnostic System Check - Wiper/Washer
2	Turn the ignition ON, with the engine OFF. Operate the front and rear wiper switch through all switch positions. Do the wiper system operate normally?	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 3
3	Are the wipers inoperative in the front and rear?	Go to Step 21	Go to Step 4
4	Are the wipers only inoperative in the front?	Go to Step 5	Go to Step 9
5	Is there only one mode inoperative in the front wipers?	Go to Step 6	Go to Step 8
6	Is the mode intermittent?	Go to Step 15	Go to Step 7
7	Is the mode LOW or MIST?	Go to Step 16	Go to Step 18
8	Connect a test lamp between the HIGH front wiper motor control circuit and the front wiper motor ground circuit. Turn the front wipers to HIGH. Does the test lamp illuminate?	Go to Step 23	Go to Step 20
9	The rear wipers are inoperative. Connect a test lamp between the rear wiper relay voltage control circuit and a good ground. Turn the rear wipers to intermittent. Does the test lamp illuminate?	Go to Step 10	Go to Step 11
10	Connect a test lamp between the rear wiper motor voltage control circuit and the rear wiper motor ground. Does the test lamp illuminate?	Go to Step 23	Go to Step 12
11	Connect a test lamp between the rear wiper relay voltage circuit and the rear wiper relay control circuit. Does the test lamp illuminate?	Go to Step 29	Go to Step 13
12	Connect a test lamp between the rear wiper motor voltage control circuit and a good ground. Does the test lamp illuminate?	Go to Step 25	Go to Step 26
13	Connect a test lamp between the rear wiper input control circuit and a good ground. Does the test lamp illuminate?	Go to Step 24	Go to Step 14
14	Turn OFF the ignition. Disconnect the windshield wiper washer switch. Test the wiper input control circuit for an open or short to ground. Did you find and correct the condition?	Go to Step 31	Go to Step 22
15	Connect a test lamp between the front wiper input control circuit and a good ground. Turn the front wipers to intermittent. Does the test lamp illuminate?	Go to Step 24	Go to Step 22
16	Connect a test lamp at the LOW/MIST control circuit at the front wiper motor and a good ground. Turn the front wiper switch to LOW or MIST. Does the test lamp illuminate?	Go to Step 23	Go to Step 17
17	Turn OFF the ignition. Disconnect the windshield wiper washer switch connector. Test the LOW/MIST control circuit for an open or a short to ground. Did you find and correct the condition?	Go to Step 31	Go to Step 22
18	The inoperative mode is HIGH. Connect a test lamp at the HIGH control circuit at the front wiper motor and a good ground. Turn the front wiper switch to HIGH. Does the test lamp illuminate?	Go to Step 23	Go to Step 19
19	Turn OFF the ignition. Disconnect the windshield wiper washer switch connector. Test the high control circuit for an open or a short to ground. Did you find and correct the condition?	Go to Step 31	Go to Step 22
20	Connect a test lamp between the HIGH front wiper motor control circuit and a good ground. Does the test lamp illuminate?	Go to Step 25	Go to Step 22
21	Test the ground circuit for the wiper motors for an open at the splice pack G301. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 31	Go to Step 22
22	Inspect for poor connections at the harness connector of the windshield wiper washer switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 31	Go to Step 27
23	Inspect for poor connections at the harness connector of the wiper motor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 31	Go to Step 28
24	Inspect for poor connections at the harness connector of the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 31	Go to Step 30
25	Repair an open in the wiper motor ground circuit. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you complete the repair?	Go to Step 31	-
26	Repair an open or short to ground in the rear wiper motor voltage control circuit. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you complete the repair?	Go to Step 31	-
27	Replace the windshield wiper washer switch. Refer to Multifunction, Turn Signal Switch Replacement in Steering Wheel and Column. Did you complete the replacement?	Go to Step 31	-
28	Replace the wiper motor. Refer to Wiper Motor Replacement . Did you complete the replacement?	Go to Step 31	-
29	Replace the rear wiper relay. Refer to Relay Replacement (Within an Electrical Center) or Relay Replacement (Attached to Wire Harness) in Wiring Systems. Did you complete the replacement?	Go to Step 31	-
