OnStar Buttons and Microphone Input Test








'03 Model

1. Pry off the OnStar buttons and microphone/homelink buttons.

2. Inspect the connector and socket terminals to be sure they are all making good contact.

^ If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

^ If the terminals look OK, make the following input tests at the connector.

- If any test indicates a problem, find and correct the cause, then recheck the system.

- If all the input tests prove OK, the switches and microphone must be faulty; replace it.
