Rear Blower - Without A/C

- Make sure that RR HVAC FUSE A/C MAXI FUSE or ILLUM FUSE 14 are not open. IF any fuse(s) is open then LOCATE and REPAIR source of overload and REPLACE fuse(s).
- Check that grounds G200 and G105 are clean and tight.
- Check that all of the relays are properly mated to their connectors
- Check 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 the system operational (under load).
- Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer "Troubleshooting Procedures"). Diagnostic Aids
