1. DEFOGGER SWITCH
Move rear window defogger switch to each position and check continuity between terminals as indicated in table:
2. DEFOGGER RELAY
Check continuity between terminals as indicated in table, when connecting the battery to terminal No.1 and No.3.
3. HEAT WIRES
1. Start the engine so that battery is being charged.
2. Turn defogger switch to ON.
3. Check each heat wire at its center position for discontinuity by setting direct current voltmeter.
Normal indication is about 6 volts.
NOTE: When measuring voltage, wind a piece of tin toil around the tip of the tester probe and press the foil against the wire with your finger.
4. When tester indicates 12 volts when its probe reaches point "A", a broken circuit occurs between point "A" and the negative terminal. Slowly move tester probe toward the negative terminal while contacting it on heat wire to locate point where tester indication changes abruptly (0 volts). This is the point where a broken circuit occurs.
When tester indicates 0 volts when its probe reaches point "A", a broken circuit occurs between point "A" and the positive terminal. Locate a point where tester indication changes abruptly (12 volts) while slowly moving tester probe toward the positive terminal.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
