Component Tests and General Diagnostics

1. Check INDIC Fuse, CLSTR Fuse, and REAR DEFOG Circuit Breaker.

2. If REAR DEFOG Circuit Breaker is open, check CKT 1040 for a short to ground.

3. Check Rear Defogger Grid for opens.

4. Check that G203 and G302 are clean and tight.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
