I purchased my 1st GM - 2021 Trail Boss. I left the Ford Raptor family.

 

The truck does not have electric folding mirrors which was important to me due to my tight parking situation. The dealer checked and was told they could install mirrors so I bought the truck. The dealer ordered all the parts, I brought it back for them to install but they can't do it. They said it is an easy swap for 2018/2019 but not 2020/2021 because when hooked up it can't "talk to the computer through the cloud". They have mirrors, wiring harnesses and some modulator but they say GM needs to write a code to make this work. There is no code written at this time.

 

They are bringing my truck back next week with all the parts they ordered (no cost to me) and refunding my upgrade cost plus $500 for my trouble.

This does not make sense to me so I am wondering if there is a way to hook up the electric folding mirrors.

That's because its never been an option on that model so it was never designed into it so the architecture to support them does not exist. Power folding mirrors are ONLY offered in Chevy's on the LTZ and High Country.  Its a marketing decision that most buyers don't want that feature on Trail Boss.

Welcome to the world of 21st Century vehicles. The Body Control Module (BCM) needs to be reflashed to work with those mirrors - otherwise the computer won't know they're there, and will be unable to control them. Sounds like the information in the reflash hasn't been created. Usually you can just take that info from another model, but of course, this is 2021, so who knows what pitfalls and nightmares lay in wait for us mechanics out here in the future with these ones. Maybe they built it so that these things wouldn't be easy. GM does crap like this all the time.

 

Anyway, hope you have better luck with it than I had with my truck. It's been nothing but trouble literally since the day it rolled off the showroom floor, and continues dollaring me to death at barely over 100k miles today. Yesterday I bondoed and rattle-canned the rot holes over both rear fenders. Thing has been a garage queen since day 1, and still rots out ... GOOD LUCK.

 

P.S. - Hope you've got a healthy wallet, because she's gonna be skinny after this one ...

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
