Is this the part where you can adjust your gain?
I have a TBC fault, and have cleaned the connections, and checked the wireing and it all looks good.
On the part where you can control the gain, mine is at 10 and i can not lower it, the button is just sitting there and no contact to the back. i want to take it apart, but cant seem to figure out how to remove the unit without taking the entire dash apart again.
