i have a 2004 silverado the rear view video just had the passenger airbag on or off light.
i put a newer one in that was compass and temp and onstar.
i got the compass to work but i cant reset the temp. it just says oc.
any ideas???

 

You have rear view Video?

 

nope its just a mirror off a newer silverado

 

Oh okay... I never heard of it before if you had.

You may want to check your wiring and see if you shorted out the sensor that's by the grille.

 

I just googled your problem and OC means there's an Open Circuit.. You need to replace your sensor.

 

ok thanks man
