Troubleshooting Hints - Steering Wheel Controls

1. Check for too much lubricant or lack of lubricant on the Cancel Cam.
2. Check the surface of the Cancel Cam for particles of dirt or metal shavings in the grease. The Cancel Cam surface can be cleaned and relubricated using GM Part No. 26001884 Dielectric Grease.
3. Check the Cancel Cam for worn slip rings, replace if the nickel plating is grooved.
4. Check condition of spring loaded contacts on Turn Signal Switch:

a. Check for corrosion.
b. Check spring condition, they should easily spring up after being depressed

5. Inspect to see if the Steering Wheel has been making contact with the Cancel Cam. Re-torque the Steering Wheel to specifications.
6. Check for possible bent or damaged optical devices.
7. Check all connectors for loose or corroded terminals.
8. If some but not all Steering Wheel Control Head Illumination Lights are inoperative, replace the Steering Wheel Control Head.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
