Troubleshooting Hints - Heated Seats

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check I/P Fuse #18. If open, repair short to ground in CKT 541.
2. Check I/P Fuse #40. If open, repair short to ground in CKT 2340.
^ 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 (refer to General Troubleshooting Procedures). Diagnostic Aids
