Power Folding Mirrors

So I recently purchased an LTZ with the power folding mirrors.  I knew before I made the purchase that the truck wouldn't fit through my garage doors with the mirrors extended.  So I have to fold them in every time I park in my garage and then unfold them every time I leave.  I am just wondering if doing this daily will kill the motors.  Not that I have a whole lot of choice in the matter.  If they break I'll just have to fix them.  More curious is anyone here had any experience with GM folding mirror issues.  Thanks.

Electric motors typically burn out because they overheat, otherwise they last for thousands of hours without any maintenance or attention.  The motors in the mirrors run for a very short time and are unlikely to burnout.  Most likely problem would be damage to the gearing, which seems unlikely in normal usage because they can be folded manually without any harm to the mirror.  Use them as needed - they'll probably last for a very long time.

I fold my mirrors almost every time I park, I'm not worried about it.

Fold mine numerous times a day, that is why I bought a truck with the option, lots of things will break, all can be fixed or replaced.

I had power folding mirrors on my 10 year old tundra before I upgraded to my current HD. Always used them when parking, never had an issue.

Yes, they will break.  There is a tiny plastic gear in there (same exact one used in the previous generation).  The gear teeth are like .050" tall, very thin, and mesh with a metal gear.  So yes, that same plastic gear that has plagued the previous gen is still in there all the same, so do a quick search and you will find that will also break.  The motors also die, but more often the plastic gear fails.  The plastic gear fails faster if you manually fold, since that overloads the mechanism.  

 

The good news is there is a metal gear / higher torque motor fix for these and the install on this latest generation is VERY easy.  The trim getting the mirror apart is much easier than on the previous generation and the drive unit itself is similar but has a plastic cover on it as opposed to metal.  The plastic cover can be easily pried off the drive unit and the gears/motor accessed.

 

Make sure to also replace the OEM motor but retain the circuit board in that new drive unit.  The OEM motor absolutely WILL NOT work with a metal spur gear.  IT will short out the BCM, which costs roughly $1,000 and is a real headache to diagnose and replace.

I too got power folding mirrors and specifically so people wont take my mirror out....where I live streets are tight and these things stick way out....my 1500 got its mirror taken out in first month and it was parked on street....

 

what I am wondering though is their a way that they can automatically fold and unfold when truck is started and turned off?.....seems like their would be a way to do this with a connector or something

Hold the door lock button for a few seconds and they will fold in. Hold the unlock button for them to unfold.

You don't have to be in the truck to do it. You can use the FOB to do it while walking up to it if you want

that sucks my truck doesn't have that feature even though I have conv 2 pkg and premium infotainment.....just looked through manual and found it in "comfort and convienence".....when I open that up all I have is chime volume, nothing for mirrors

 

and I tried the fob and nothing, as well as inside the vehicle

 

probably have to have LTZ or HC

I believe you have to have power-extending mirrors (DZC) for remote features, not just power folding (DBG).

My mirrors on my 2017 2500HD were power folding and the passenger side wouldn't fold in all the way most of the time by the end (65k miles) and the drivers mirror would not fold at all the odd time. The motors worked fine, but the gear inside would skip. And I RARELY used them as I live in the country and rarely have to worry about city traffic.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By SoCal Angler · Posted

      After my recent rear end bumper damage, body shop has made the repairs and included a new OEM receiver hitch.  I started thinking about how it was tightened...to specs or by hand or ??.  I called the body shop and asked and they said it was tightened by an impact gun.  I said I wanted it tightened to OEM specs.  They said no problem, bring it to shop today and they will torque to specs, which they say is 74 ft/lbs.   A couple of questions,,,,   1.  Should new bolts have been used?  If so, how many are there (bill shows one and four (I assume different areas of receiver).   2.,  Since they torqued with impact gun and now are going to probably loosen and then torque to spces, will that damage/stretch the bolts?   3.  If old bolts were reused (truck has 9000 miles), is that a problem?   4.  Any other things iI may have missed with regard to receiver replacement?   Thanks!

      Defective Brake Pad Wear Sensor?

      By newdude · Posted

      Is this supposed to be in English?  "close to 100 fake, new brake pads sign on the dash board"     Pull the wheels off.  Check the brake pad thickness.  Check the sensors out.  You could have good pads and the sensors aren't in to the worn out position, but have an electrical fault with the sensor or the plug wiring to the sensor.

      Tomorrow I go in for my third joint replacement in jus a little over a year year!  I am not worried about the surgery but I am a little annoyed about going through the recovery process again!  I keep my frustrations to myself as I do appreciate that I am truly lucky.  Knee, hip, and shoulder replacements are routine, safe and improve mobility.  The next couple of days will be slow but every day following will see steady improvement in my mobility.

      OCI, not when but why?

      Practical Application ISO 4406   I think this oil cleanliness thing is going to boil down to ones personal resolve. The information is there but applying it I believe will test your commitment to the machine. Implementation would involve building or buying a prefilter or purchase of an "ISOCLEAN" oil. Then installing a single digit micron bypass system. A good deal of testing and about 99.9% of you are saying at that point....yea.....not my cuppa tea. So what can you do?    You already did the first step. Get educated and leave the bias at the door. Be aware of the its, cleanliness, importance.    Do your own work if you can. Keep the equipment clean. Not just your funnel but the engine bay. Use sealed containers. Think it through.    I believe you will find, as I did, that the tightest absolute full flow filters (Beta 200) will be around 20 micron. That will yield on average a Beta 75 of 10-15 micron. They are few in number by brand and price point. Loose filters are a dime a dozen and even the best brands have lines of loose filters. Some cleverly marketed as "Extended Service". Others will market flow over efficiency. But I think the take away once informed is that the extra cost of the best offered is a bargain. There are cheaper filters with good efficiency that are equal in performance to niche brands with big prices. Your Quick Lube is about a 40 micron unit. This is where your dealer is a plus. the AC-Delco filter is a good step up from those places. Even better if you specify the UPF line.    Be skeptical of marketing. Buying an oil that is made from GTL advertised as the cleanest base oil is using a truth to support a lie. While GTL's are made from debris free gas the processing equipment and post handling is just like any other oil. It also ignores the fact that PAO's and Esters are also gas in origin. Any private prescreening testing you would do, and some have done, would yield a result only good for the batch you tested. AMSOIL and Schaeffer's have built a reputation for paying attention to this detail.    Context. Cold starts account for at least 75%, or more, of an engines wear. But of the remaining 25% ish, over 80% is caused by particle count. Now where do we find high milage motors that use this type of information efficiently? OTR trucking!      Now, anyone want to build a prefilter or off line cleaning system anyway?
