Seriously, since that other post about auto dimming mirrors it made me take notice of mine and it has the switches and dimming **** on it and a wire comming out the top of it so I messed around under the headliner and found the wire to hook it up with but then it started making a grinding sound like a running motor in it, continuously. Any idea how these things work or how to fix this thing?
Thanks

 

I haven't the foggiest... but what does NOS have to do with it at all?

 

It's obvious. You want the mirror to dim when you hit the juice, right?

 

The mirror sounds meaner than the engine in the car. Stupid, I know. Anyone have any ideas???
Thanks.

 

I dont think its that obvious... Im still curious about the NOS...
