The make up air routine will run as soon as you start the truck. It's a pretty clear low pitched whistling sound. Don't block the air intake, you're more likely to ruin the compressor and that's a more expensive fix than pulling vacuum and refilling.
You're more likely to ruin something plugging it than preserving anything. It should never pull from the atmosphere and it does have a drying process to limit moisture. If you ever hear a low pitch whistle it's going through the refill procedure and that should be the point to check for leaks.
See my post in one of the other air suspension threads: https://www.ramforum.com/threads/ride-height-with-alfaobd-air-suspension.148828/post-2839539
The valve block still cycles even with the air compressor fuse being pulled. The valve block reads the pressures so it cycles through all the air...
Probably not the best idea. Do a proper leak check. I have learned this lesson the hard way and spent money replacing parts that didn't need to be replaced. In my case, the leaks have been on the fittings on the tank and tank manifold. If you have AlfaOBD, use it daily to check the air mass in...
I am selling a surround view camera module for a MY19-MY21 2500/3500 UConnect 4 trucks. I moved to a UC5 radio and had to get a UC5 camera module as the UC4 CVPM was not compatible. The PN for the module is 04672644AJ. This module has inputs for the four surround cameras and the cargo camera...
I am selling an LED CHMSL with the digital cargo camera used with surround view compatible with MY19+ 2500/3500s. I replaced my CHMSL with one that includes the digital rearview mirror camera so I no longer need this one. Part number is 68367388AB.
Looking to get $300 shipped OBO.
I am selling my digital rearview mirror that I was planning on retrofitting into my 4th gen. The part number is 68448641AB and it's listed as compatible with MY21+ 1500s and MY21 2500/3500s. The mirror mount is for trucks that have the FCW/ACC but it is relatively easy to swap the mount from...
I am selling a 2021 1500 Classic cluster PN 68505996AA. It should fit all 4th gens though you will have a flashing "P" when in Park depending on the years. I can correct the odometer and hours before shipping if needed.
Looking to get $350 shipped OBO and that includes odometer and hour...
I am selling a 2020 1500 Classic cluster PN 68402202AA. I can correct the odometer and hours before shipping if needed.
Looking to get $350 shipped OBO and that includes odometer and hour programming.
SOLD
EDIT: It should fit all 4th gens though you will have a flashing "P" when in Park...
It can be added to trucks going back as far as 2014 (potentially even 2013). 2500/3500 are just a few setting changes to enable the BSM after installing the 5th gen HD tail lights and connecting the BSMs to power and CAN bus. 1500s require a conversion module to make the blind spot modules work...
I had the same issue when I did the swap originally and ended up having to swap the BCM. My 2015 BCM would allow me to set the DCSD setting but wouldn't actually broadcast it on the network. It's possible that early build 2016s have the same issue.
