How to fix a broken car mirror support

I show the step by step repair of a side mirror that was knocked off by a minor impact. The vehicle shown is a 2000 Suburban, but the design is similar to ma…

Thank you so much for posting. This really helped me get a handle on my
issue. I used a piece of a 3/4 PVC coupler to push the “castle nut” down. I
cut a small chunk out so I could do the entire thing with removing the
mirror housing.

You make a good point, Mathieu. Where I live now, near the ocean, mirror
heaters are almost never needed. Actually it might be connected to the rear
heater control, I haven’t checked. You notice there was brownish staining
of the plastic on the electrical contact behind the mirror. In retrospect I
wonder if there was a bad connection there at one point, either on my
vehicle or the original vehicle this mirror was on.

spelunkerd says:

Yes, if it had happened inside the warranty period GM has a modified bolt
called a J-hook to fix it. But outside of the warranty I suspect they will
charge you for it, and what I did above seems to have worked fine. I
believe the J-hook holds it so well that minor trauma would break the
support rather than allowing it to fall off, undamaged.

Do you find a way to add yourself the heat function o your truck. On my
corolla 2001 I have the wirering to add the anti-fog head light. It’s will
cost me 400 $ to add this functionnality. But heater is might be just a
button to add on the dash to be able to use It.

spelunkerd says:

Ha, ha, unlucky seems like the norm around here. I prefer driving old cars,
and with a big family there is lots of work. Thanks for watching.

spelunkerd says:

Yeah, the original mirror on this vehicle was broken off by random teenage
vandals, and half those little clips were broken, and the mirror frame was
destroyed. I had to replace the whole mirror with a junk yard part, which I
picked up for $40 — the part shown. I’m not sure what model this part is
from, but Chev used that style of mirror for many years. Thanks for
watching, Terry.

spelunkerd says:

That’s expensive, I didn’t know how much it costs. I could make a J bracket
in my shop with scrap parts.

spelunkerd says:

That’s very resourceful, good job. The J-bracket uses a J shaped bar that
goes though the ring, with a nut on the end holding the castle nut on. Of
course rigid techniques lose some of the ability to fall off without
permanent damage.

Ha ha, your supervisor seems happy :-), smashing dog 🙂 Ive seen those
washer/clip before, and they can get a bit weak, ive often got a small pair
of pointed nose plyers and just tweaked the center tangs a tiny bit to
restore the grip. Allways enjoy your videos, your a clever man that allways
explains things in a measured and thoughtfull way, and great tips included
🙂

I got it at a discount store. I like the blue color it give out, bordering
on UV. It seems a little better when looking for UV dye. Hey, thanks for
watching.

spelunkerd says:

Yeah, it’s running great now and I’m glad I didn’t toss it when the
transfer case was shot last year.

spelunkerd says:

You’re welcome, and thanks for the feedback.

I love the led worklight. I’m guessing you made that. That would be very
handy.

Hi, great video, I had no idea how this was held together. Unfortunately
for me, as soon as I pressed the flattened castle ring over the shaft and
moved the mirror, it popped right back off. I took it apart again and
pressed the castle ring on again but then I drilled and tapped two small
short 10/32 machine screws just above the castle ring on the shaft. Now the
ring can’t pop off again. Put it all together and it works perfectly.

Thank you so much for posting this! You’ve saved me time and money.

I just realized that if you chain all your vids together, it is a tutorial
on building a 2000 suburban from scratch lol!

Dave Griffin says:

thank-you for that video, that’s exactly what happened to my 2000
silverado… i would have been lost without it… Dave

Billy DeVincentis says:

I agree. I was considering buying a used mirror but I wanted to do this
without spending any money, also the j bracket kit is ridiculously priced
$56, not worth it in my opinion, my repair will hopefully last forever.

stuzman52 says:

Hi Dave, I worked on a motorized mirror on a GM product and as careful as I
was to remove the mirror following the service manual procedure, that
fringing mirror broke right in my hands. What a pain! Glad to see that you
got yours out with no problem. Nice work and a happy looking dog that you
got there.

Murphys Luck says:

just purchased a 2000 suburban for myself and my passenger side review
mirror has this problem. thanks or the video.

spelunkerd says:

I’m glad you brought the clip up. Indeed, I did flatten that castle washer
with a hammer and needle nose pliers before I put it back. On reviewing the
video later, I realized I forgot to record that part. Thanks for helping
out!

spelunkerd says:

Mine may be a little different than yours, but probably not much different.
The mirror shown is actually a junk yard replacement, since my first mirror
was completely destroyed by random teenage vandals. The original mirror
mount was almost identical, and as far as I remember the rest was fairly
similar. I believe GM used the same mirror in many models and years. Thanks
for the sub!

buddyboy4x44 says:

Good job, thank you. This is one of those jobs that does not arise too
often and thevideo showed what I can expect if/when I take a side mirror
apart. Do you deliberately break and wear stuff out so you can make
video’s. If not, you are very unlucky with your equipment as you make lots.
