Didn't see this one coming....

[markviii96]

No, the bracket will already be on the new windshield and shouldn't fall off. And in all my years I've never heard of a stereo knocking off the rearview. There had to be something else up there.

I knocked off my rearveiw, and my drivers side mirror in my mustang from my system.

OK guys, work is slowww so it's giving me time to doodle. If I were to make a custom type windshield mount, would it work? Critique my doodle.

You would then use regular adhesive to mount the base to the windshield. But would it work? I don't plan on doing this but just wanted to see if it made any sense.

kaha, you have to step back with us about 3 and 4 years ago. He was having this problem quite often. I'm sure there was also some looseness in the mirror to the bracket too at some point and then finally, he got ahold of something good that would actually hold up to not taking the mirror bracket off the glass but instead, over time, I think he weakened his glass in that one spot to the point of getting very lucky and only having that single chunk taken out. I had the same thing going on while he was too and I finally found something I thought I mixed but it was a primer that dried almost instantly and required a drop or two of glue and it held up. It wasn't $25 but was around $10 or so from what I can remember.

You don't "weaken" glass. Ya either break it or ya don't.

And I'm done on this subject. Let everyone who hasn't worked with it for 35 yrs chime in.

I appreciate all of your help. I don't think they're trying to show any disrespect, it's just that me and limit went through this years ago and are trying to come up with some reason as to why it happened.

Thanks again to for everyones help.

It's pointless. Well contrived, but pointless.
A properly mounted mirror bracket won't drop your mirror without first shattering the windshield, I don't care how many DBs of bass ya throw at it.
I've heard the claims, and am also honestly mystified. In all my years in the glass business (auto, residential, industrial, commercial) I've never seen such a thing. Never had to fix such a thing. Never heard such a claim (My stereo made my rear-view fall off). Never.
So this thread is very interesting to me.

I was just making a guess as to what happened. Maybe it didn't weaken it but it did break it in that spot where the button was applied. I'm no glass expert but I did cut it daily for a living, making TVA approved storm windows and storm doors, full view with tempered (it's the law) and then the sliding glass type with the screen. Done that for a little over 10 years. Still not a glass expert.

As for auto glass, can't say I am experienced with it but the type of break that happened was a rare one and it can't really be called a break, it was chipped out at the mirror button and it was the stereo that finally done it in. When you have bass like we have in the trunk of a Mark, the mirrors really do some jumping.

I have always heard that there is a first time for everything and it's my first time to see one fall out like that and bring glass out with the button. I went without mine for nearly a year because I got tired of it falling. I kept it in the back floorboard just in case I was ever asked. I would have said "it just now fell down" Very unlikely around here to be pulled over because of no mirror and there are no inspections.

Kaha, don't see why you seem so damn put off. Bass causes vibrations>vibrations weaken adhesive>sh!t falls off. Simple. Happens all the time in my hobby. I respect your career working in auto glass, noone I saw here was questioning your ability or expertise. Have a beer/soda and relax with us?

 

[Chris_Murder]

I'd go to an independent glass shop with good reviews that stands behind their work, as a courtesy I wouldn't try to watch them do the work, that's what they do for a living, leave them to it. I know I personally do NOT like customers watching me fix their cars and hovering. However that's just me. I would also refuse to go to anyone who wasn't using a quality or oem glass (again that's just me).

 

[Big Mike]

I'd never let anyone work on my car who wouldn't let me observe, unless I knew them (like Jamie). I mean, I don't want to tell you what to do, or bother you, but I
always keep an eye on it. I don't just leave my car to some of the chuckleheaded wrench-monkeys out there.

All cool Mike, I'm not sure what lit the fuse on my tampon either. Musta been too much negativity in Kahaland yesterday, let's have a beer.

Thought I'd resurrect this thread to Right a Wrong.
Turns out I was wrong, said I'd never seen a case of a powerful sound system busting a mirror bracket off the windshield (which is true, was always a case of someone whacking it by accident while cleaning the interior or something). I've since talked to a couple techs I work with (one of which also does car audio on the side), and asked if they'd ever seen such a thing. "Oh yeah, seen it several times. Ya realize how many DBs these amps can crank out? They get everything shaking and rattling."

Lesson in humility learned: just cos ya haven't personally seen something doesn't mean that others must be wrong.

Hmmm, crow ain't so bad if you have a good beer to wash it down with...

Good show, sir!

We've all been guilty of it rather we want to admit it or not. But now ya know




As I updated in the wdydt sticky, I got it replaced yesterday. Ends up it was replaced at some point and they failed to prep it correctly. Use your imagination as to what happens when you dont prep before installing one.

He put in extra effort to correct the problem and he did a fantastic job. Heading to the junk yard in a couple to find a non dimming ford unit.

I 'm curious to know if the glass installer had a special tool to remove the windshield trim. Did he let you watch him work?

It might be a good idea for me to replace my cracked windshield and hold off putting the trim back on before I do the repaint on my '94. I don't want to see incidental scratches on my new paint when they're done.

Although my mirror has fallen off before because of my sound system, The crack on my windshied was caused by a piece of debris that chipped the glass from a dump truck, two lanes over, ahead of us. Came out to the car after a winter freeze and there it was, a huge crack running from the chip, running across half the windshield.

sba- thanks for posting this subject. It has really helped me avoid possibly getting poor quality glass and labor. And to kaha and NoLimit on your subject knowledge.

Windshield trim is removed with a clip tool, several models available from C.R. Laurence (the US glazier supply monopoly). The Mark VIII has no trim; the black vinyl that goes around the glass is called "molding", and is either attached to or sold with the windshield.

It might be a good idea for me to replace my cracked windshield and hold off putting the trim back on before I do the repaint on my '94. I don't want to see incidental scratches on my new paint when they're done.

It's ALWAYS a good idea to pull busted glass before painting. Have your local glass shop extract the windshield, get the car painted, and then have the new glass put in. Then ya got Show Quality. If you see scratches or blemishes in the new paint after windshield installation, hold the glass shop responsible. If they are anything better than a hick outfit they will cover the costs at the painter. I've done plenty custom v-butt windshields on 30's roadsters (chop out the center post and grind everything smooth) that have taken trophies at car shows. ALWAYS after the paint. And I've never screwed up a paint job.

Seriously. If your local glass place seems like a bunch of Neanderthals, find a different glass place. Most of us take great pride in quality work and craftsmanship. I personally love watching cars take first place in shows where I did the custom glasswork.

Turns out the tab that was on my old windshield (also aftermarket as I found out) was indeed smaller then the rv needed, and here I was thinking it was a mount issue. The new tab is a little wider where there was a slight gap on the old one. Pretty sure that's where my problem was. Just a mini update.
