Rattling Door Mirror

[SCOTI]

Just like the title indicates, my passenger door mirror rattles when driving down the road. I had to replace the 'new' LMC door lock switch w/the original (new one broke on the 1st use) so I figured I would investigate the cause (tighten the hardware?) while the panel is off.

I see 2 rivet-nut style fasteners @ the top of the base & found a single external stainless screw @ the bottom of the base. I've never messed w/these later squarebody mirrors so what is the removal procedure? It appears the base gasket is not doing its job isolating vibration & requires replacement w/a new gasket (that's hopefully available).

The screw at the bottom only holds the cover on, remove it and gently lift the cover away from the base. There is a grommet in the top of the cover that the mirror arm goes through, carefully work that grommet up the post while you're moving the cover up out of the way to access the mounting bolts. Likely they just need tightening, the gasket underneath is really more a hard plastic locator/isolator. Wouldn't hurt to remove and clean while you're there.

Ok. I'll try some simple-green to help that upper grommet slide. I figured it was something like that but the cover didn't budge. I didn't want to force anything before asking questions 1st.

Inside the top of the cover there are two tension tabs that help hold it in its assembled position. Just wiggle the cover a little as you pull the bottom up and away from me door and it'll free itself.

Thanks guys.

I worked the mirror back & forth to try & loosen up the grommet. That sob was stuck pretty good but once it was moved the cover popped off like it should. I tightend the hardware & the rattle is gone.
