10	Inspect for poor connections at the PWR WDO circuit breaker. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you find and correct the condition?	-	Go to Step 29	Go to Step 27
11	Connect a test lamp between the RAP 2 fused supply voltage circuit at the junction block-I/P wiring harness to a good ground. Does the test lamp illuminate?	-	Go to Step 12	Go to Step 24
12	Repair the RAP 2 fused supply voltage circuit for high resistance or an open. Refer to CIRCUIT TESTING and WIRING REPAIRS . Did you complete the repair?	-	Go to Step 29	-
13	Connect a fused jumper wire between the RAP 2 fused supply voltage circuit and sunroof switch close/tilt up signal circuit at the sunroof switch harness connector for 2 seconds. Does the sunroof slide either to the closed or vent position?	-	Go to Step 14	Go to Step 15
14	Inspect for a poor connection at the sunroof switch and harness connector. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you find and correct the condition?	-	Go to Step 29	Go to Step 26
15	Disconnect the sunroof module harness connector. Test the sunroof switch close/tilt up signal circuit for an open, short to voltage and short to ground. Refer to CIRCUIT TESTING and WIRING REPAIRS . Did you find and correct the condition?	-	Go to Step 29	Go to Step 16
16	Connect a test lamp between the RAP 2 fused supply voltage circuit at the sunroof module harness connector and a good ground. Does the test lamp illuminate?	-	Go to Step 17	Go to Step 25
17	Connect a test lamp between the battery positive voltage circuit at the sunroof module harness connector and a good ground. Does the test lamp illuminate?	-	Go to Step 18	Go to Step 21
18	Connect a test lamp between the battery positive voltage circuit and ground circuit at the sunroof module harness connector. Does the test lamp illuminate?	-	Go to Step 19	Go to Step 22
19	Measure the resistance between the sunroof switch open/tilt down and the sunroof switch close/tilt up signal circuits. Refer to CIRCUIT TESTING . Does the resistance measure near the specified value?	OL	Go to Step 20	Go to Step 23
20	Inspect for a poor connection at the sunroof module. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you find and correct the condition?	-	Go to Step 29	Go to Step 28
21	Repair an open, high resistance or a short to ground in the battery positive voltage circuit. Refer to WIRING REPAIRS . Did you complete the repair?	-	Go to Step 29	-
22	Repair the ground circuit of the sunroof module for an open or high resistance. Refer to CIRCUIT TESTING and WIRING REPAIRS . Did you complete the repair?	-	Go to Step 29	-
23	Repair a short between the sunroof switch open/tilt down and sunroof switch close/tilt up signal circuits. Refer to WIRING REPAIRS . Did you complete the repair?	-	Go to Step 29	-
24	Repair a poor connection in the RAP 2 fused supply voltage circuit harness connector at the junction block-I/P wiring harness. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you complete the repair?	-	Go to Step 29	-
