So I was out washing the truck today and was bound and determined to fix my shaking drivers side SS mirror. The mirror was getting so bad that you couldn't even get a clear picture/view out of it while going down the road. Needless to say it was really annoying. So I very gingerly took off the mirror part and started to inspect the actuator itself. What I found out is the three screws that you can see in the motor part of the picture was loose. The screws on the outer part (4) were still tight. So I just tightened them up, replaced the mirror and everything seems good as new. Sorry I didn't get pictures of the back of the glass but it's pretty self explanatory on how it comes off when you move the mirror to see the back. But anyway here's the pics.
