At $400 it sounds like he is going to replace it, and not repair it.
Items like outside mirrors do not easily lend themself to repair.
They are pretty much go/no go items.

Taking the inside door panel off is easy.
Roll the window down.
Remove any screws holding the trim (should be by the door release lever, and possible 1 or 2 at the edge of the panel).
Also, some models have bigger screws/bolts just under the armrest, remove those also.
GM uses a plastic "christmas tree" fastner in the door panels. It is easiest if you purchase a door panel removal tool (Couple of $ at any auto parts store).
Start at the lower edge, slide the tool between the trim panel and the door, and pry up gently.
Work your way around the door (F&R edges, and the lower) until the panel is free,
Then slide the panel up (it is hooked into the window channel).

To remove the mirror, there are 3 nuts on the back side. Remove those, while someone is holding the mirror, and then pull the mirror out a little. Disconnect the wiring plug to the mirror.

This whole process shouldn't take you more then 10 to 15 minutes. People that do it all the time usually do it in 3 to 5 min. So it is a simple job.

Reinstalling it, is just the reverse of the removal.

You may want to look at aftermarket mirrors, or you may what to try a salvage yard for a replacement part if the factory replacements are too expensive.
As mentioned earlier, these are go/no go items, so there are no "instructions" on how to fix them.

How to fix a loose wing mirror freelander

If it's loose from the door, you need to remove the inner door panel to access the screws that hold the mirror in place on the door itself. To remove the inner door panel may simply involve removing some screws, but some models require a special upholstery tool to loosen the panel fron the clips. Once the panel is loose, tighten the mirror and replace the inner panel. Be cautious with door switch wiring!

How to tighten the side mirror on a hummer H3

OK. Just to make it clear it was the mirror vibrating on the swivel not vibrating on the door. I went to the store and purchased a package of those plastic "velcro" pieces. I turned the mirror in towards the door and cut a piece of the plastic big enough to fit under the mirror so it wasn't sticking out when I slide the mirror back into place. Took the backing off the plastic velcro piece and stick it to the mirror stand under where the mirror would rotate back to normal. The plastic acted as a shim and the mirror does not shack anymore. I tried to take the plastic piece off the mirror to see if there was any screws I could tighten but it looked like the mirror swiveled around a post and could not be tightened. Any why, this did the trick. I hope this will help others.

Passenger side mirror is loose, how do i tighten it?

If the mirror housing is loose where it attaches to the door panel, you will probably have to remove the inner (inside the car) door panel to gain access the 2 or 3 nuts or bolts that secure the housing to the door and tighten them.

The drivers side door mirror glass(not the whole unit,just the actual mirror itself ) is loose & vibrates when you tighten it up?

Either it's a cheap replacement mirror that can't be tightened. Or, the original (oe) has been hit hard enough to displace on of the plastic attachments behind the mirror. Adjust the mirror to the extreme right so you can peek behind the mirror to look for an displaced attachment. Line the 2 points up and firmly with a gloved hand, push into place until you hear it "click" into place. Good luck

How to replace the he drive-side mirror of a 1999 Camry

Just remove the plastic triangular cover that is on the door. There may be a speaker behind it that will also have to be removed. Once these are off just unplug the little white wiring harness and remove the three 10mm nuts that secure the mirror housing to the door.

when you are tightening up the new mirror be sure not to over tighten as you could break the new part.

1998 SL2: driver's side wing mirror vibrates in its housing. The dealer wants $300 to fix it. It's annoying, but not a safety hazard that must be fixed. I would like to remove the unit, take it apart,...

Hi allenwh,

Only $300.00 to fix? Wow. How much to replace? Here are some other, less expensive options and advice. First, save your money.

If it's a manual mirror (little joystick adjuster on the door), you can unscrew the trim panel and check the control rods (sort of like brake lines on a bicycle). Don't think this will be very effective though.

If it's electric, all the moving (rattling) parts are inside the mirror.

To actually get to them to make adjustments would be somewhat difficult if not destructive. Once the glass is attached, it's pretty much there forever.

An alternative to the repair would be a replacement with a twist

Call a few of your local salvage yards.
See if the have a 98 SL2 mirror in your color. Most of the more established yards have this info on computer and mirrors are something they keep an inventory of.

To replace it, you'll need to pull the door panel But you were planning on that anyhow. At least this way you aren't wondering if it's going to be fixable.

If you decide to go this route, Click on the ASK button. I'll get you through.

Bottom Line: Replace the mirror yourself with a used one. Cost should be less than $40.00

Remember: Good things happen for those who Rate!!!
