Test 3: Right Front Window Is Inoperative

Disconnect right front window switch connector. Turn ignition switch to RUN position. Using DVOM, measure voltage between right front window switch connector terminal "H" (Tan wire) and battery voltage. See Fig 1 . If 10-15 volts does not exist, go to next step. If 10-15 volts exists, go to step 5 .
Check for open in Tan wire between right front window switch connector and master switch assembly. If circuit is open, go to next step. If circuit is okay, go to step 4 .
Repair open in Tan wire and recheck system.
Replace master switch assembly and recheck system.
Using DVOM, measure voltage between right front window switch connector terminal "H" (Tan wire) and battery voltage. Press and hold right front window switch on master switch assembly in DOWN position. If 10-15 volts exists, go to next step. If 10-15 volts does not exist, go to step 8 .
Check for short to ground in Tan wire between right front window switch connector and master switch assembly. If circuit is shorted, go to next step. If circuit is okay, go to step 11 .
Repair short to ground in Tan wire and recheck system.
Using DVOM, check voltage between right front window switch connector terminal "D" (Light Blue wire) and battery voltage. If 10-15 volts does not exist, go to next step. If 10-15 volts exists, go to step 11 .
Check for open in Light Blue wire between right front window switch connector and master switch assembly. If circuit is open, go to next step. If circuit is okay, go to step 4 .
Repair open in Light Blue wire and recheck system.
Using DVOM, check voltage between right front window switch connector terminal "D" (Light Blue wire) and battery voltage. Press and hold right front window switch on master switch assembly in UP position. If 10-15 volts exists, go to next step. If 10-15 volts does not exist, go to step 14 .
Check for short to ground in Light Blue wire between right front window switch connector and master switch assembly. If circuit is shorted to ground, go to next step. If circuit is okay, go to step 4 .
Repair short to ground in Light Blue wire and recheck system.
Using DVOM, check voltage between right front window switch connector terminal "F" (Pink wire on Eldorado; Dark Blue wire on DeVille) and ground. If 10-15 volts does not exist, go to next step. If 10-15 volts exists, go to step 16 .
Repair open or short to ground in Pink wire or Dark Blue wire. See WIRING DIAGRAMS . Recheck system.
Connect right front window switch connector. Disconnect right front window motor connector. Using DVOM, check voltage between right front window motor connector Brown wire and Dark Blue wire terminals. Press right front window switch to UP and DOWN positions. If 10-15 volts exists when switch is pressed, go to next step. If 10-15 volts does not exist when switch is pressed, go to step 18 .
Replace window motor and recheck system.
Check for open or short to ground in Brown wire between right front window switch connector and motor. If circuit is faulty, go to next step. If circuit is okay, go to step 20 .
Repair open or short to ground in Brown wire and recheck system.
Check for short to ground in Dark Blue wire between right front window switch connector and motor. If circuit is faulty, go to next step. If circuit is okay, go to step 22 .
Repair open or short to ground in Dark Blue wire and recheck system.
Replace right front window switch and recheck system.
