Power Window System Current Test: Camry
- Disconnect driver's power window master switch harness connector. Connect positive lead of ammeter to driver's power window master switch connector (harness side) terminal No. 3 (White/Black wire).
- Connect ammeter negative lead to negative terminal of 12-volt battery. Connect jumper wire between positive battery terminal and driver's power window switch harness connector terminal No. 6 (Red/Blue wire). See Figure.
- As driver's window is lowered, current should be about 7 amps. When window operation is stopped, current should increase to about 14.5 amps or more. If current is as described, replace driver's power window switch. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. If current is not as described, check and repair appropriate circuit as necessary. See WIRING DIAGRAMS .
