I changed out my mirrors. Mine is a 2021/2 Classic Express Quad cab. Just had powered mirrors in plain black.
I got a pair of powerfold, heated, chrome, puddle, indicator mirrors off a 2018/9 Laramie (see post two above for mirror part numbers).
New modules (102AD, 103AD) as originals were 100AD and 101AD, plus the correct door switch.
Followed instructions for Alfaobd on post 4, copied and pasted below:
Regular Mirror Codes w/Power fold:
Doors Configuration:
> Folding mirrors Present: Set/yes
> Mirror Turn Signals Present: set/yes
> Mirror Approach Lights Present: set/yes
> Electro-chromatic Driver Mirror Present: set/yes
> Electro-chromatic passenger mirror Present: set/yes
Doors Configuration:
> Driver Memory Mirrors Present: yes/set
> Passenger Memory Mirrors Present: yes/set
CustSetMenu 2:
> Tilt mirror in reverse: yes/set
Everything worked except for Tilt in Reverse. BUT I went into the settings menu on the 8.4" screen and went to mirrors. Has a tick box for Mirrors Fold in Reverse. Ticked that and they work.
Mine doesn't have a rear window demister/heater so not sure if the heated mirrors will work or how to turn them on manually, but I don't need them anyway.
I finally managed to get the time to convert my mirrors last weekend.
Same parts ie mirrors, modules, and door switch.
After programming everything works, except for the mirror turn signal on the left-hand side.
I was wondering if it had anything to do with any wiring modifications during the local RHD conversion.
On the right-hand side mirror the body mounted turn signal does not flash anymore but the turn signal in the mirror works.
On the left-hand side the body mounted turn signal works but not the turn signal in the mirror.
Using AlphaOBD, connecting to the door modules I can test the indicator function for each mirror and the result is the same.
Ultimately, I would like for both turn signals (mirror and body mounted) to work on both sides.
With the original standard non turn signal mirrors, both of the body mounted turn signals were operating correctly.
I wonder if it would be as simple as wire tapping into the working signal on each side and connecting that to the non-working light respectively to get them to work.
