Celica & RAV4
- Disconnect combination switch connector. Turn wiper/washer switch to INT position. Rotate intermittent time control to FAST position. Connect fused jumper between battery voltage and terminal No. 17. Connect jumper wire between ground and terminal No. 16. See Figure. Connect DVOM positive lead to terminal No. 7 and negative lead to terminal No. 16. DVOM should indicate battery voltage.
- With DVOM connected, momentarily connect terminals No. 16 and 2 with a fused jumper. With jumper connected to terminal No. 2, move jumper from terminal No. 16 to terminal No. 17. Monitor DVOM reading while rotating intermittent time control from SLOW to FAST positions. In SLOW position, voltage will change from zero to battery voltage in 10-15 seconds. In FAST position, voltage will change from zero to battery voltage in 1-3 seconds. If operation is not as specified, replace wiper/washer switch. See FRONT WIPER SWITCH under REMOVAL & INSTALLATION.
