Is the light flashing?

The Blind Spot Module is no good

1. Visually inspect the right side BSM control module. Look for loose connections, or obvious damage or water intrusion.

2. Check to see if you can establish communication with the right side BSM with a scan tool.

3. Check the right side BSM for power on pin B Black/Yellow wire, this should be battery voltage and light a test light bulb brightly.

4. Check the right side BSM for ground on pin A Black wire. You should have .05 V or less here, add a ground as needed.

5. Check the CAN lines to the BSM control module on pins H Red and G Blue. Expect between 2.3-2.7 V on these. Compare to the left side.

It will either be the left side module or right side module

You need scan tool that will read the BSM to see which of the two is bad
