TROUBLE SHOOTING
Note. Troubleshooting procedures for Camry, Camry Solara, Celica, Corolla, ECHO, and MR2 are not available from manufacturer.
Note. Use illustration for trouble shooting procedures. (Scheme 1)- see scheme 7.
Scheme 1
Scheme 2
POWER WINDOW SYSTEM CURRENT TEST
Note. System circuit breaker opens 4-40 seconds (4-90 seconds on Celica and Avalon) after window operation stops. Ensure circuit test is performed before circuit breaker operates.
POWER WINDOW SWITCH CONTINUITY TEST (DRIVER'S SWITCH)
Note. Avalon incorporates separate ECUs which includes window switches for both driver and passenger front door. Switch continuity testing is not available.
Using an ohmmeter, check continuity between specified terminals with driver's power window switch in specified position. See appropriate DRIVER'S POWER WINDOW SWITCH CONTINUITY TEST table. (Scheme 3)- (Scheme 10). If continuity does not exist at specified terminals, replace power window switch. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION.

INTEGRATION RELAY TEST
Note. Integration relay supplies voltage to the power relay. Testing for Camry Solara and Corolla is not available.
POWER MAIN RELAY TEST
Remove power main relay. See POWER MAIN RELAY LOCATION table. Using an ohmmeter, check continuity between terminals No. 1 and 2. Continuity should exist. (Scheme 16)or (Scheme 17). Apply battery voltage to terminal No. 1 and ground terminal No. 2. Continuity should exist between terminals No. 3 and 5. If continuity is not as specified, replace power main relay.

POWER WINDOW MOTOR TEST
Using a 12-volt battery, connect positive battery lead to either power window motor terminal. Connect negative battery lead to other power window motor connector terminal. Motor should operate. Reverse battery leads. Motor should operate in opposite direction. If motor does not test as described, replace power window motor.
