RAM 4WD SERV Failure - Easy Fix 

Thank you for your timely video. My 4wd service light went on today after a short trip last weekend, but I had a different problem instead of the actuator itself. We have ground squirrels always running around our house and my two dogs always seem to chase them under our vehicles. They were chasing one as we returned and I did not notice that it ran under the truck to get away. One of the dogs chased it up into the motor bay and apparently chewed the actuator harness to get to it. Thanks to the video I started with your advise and immediately found the problem and repaired it fairly quickly. This is the second vehicle we've had this happen to, the first had so much damage that I traded it off. I will use a .22 rifle again to make a more permanent repair

Thank you for the very imformative series! I will be replacing mine as well! God bless and happy camping!

Thank you for sharing… this video has been very helpful 🙏🏼

Thank you for the video. Mine did this a few weeks ago while I was towing my RV, and I was 6 hours from home. I was in a panic as there was no dealership around for a very long way. At my next stop, I shut the engine off and when I came back the light was off. I have put hundreds and hundreds of more miles on it, mostly towing my trailer, and it has not come back on. I'm at least relieved to know what is causing the light to come on, but now I know it won't leave me stranded. This was also a common failure point on the YJ Wranglers, although their biggest problem was the actuator was vacuum driven. When the TJ Wrangler came out in 1997, they had done away with the CAD actuator and it was simply a solid axle which spun the transfer case all the time, so I'm pretty confident the actuator here won't cause any major issues if it fails. I'm also happy that it is something I can fix myself because I doubt this is going to fall under the powertrain warranty, and I have over 60,000 miles on my truck.

Thank you very much for your input

Thank You very much Sir. My 3500 did this @ 200000

Would you recommend aftermarket over OEM? My issue is similar. The service 4wd only comes on when I try to shift into it but goes out shortly there after.

when you said jacked up the right side, could you clarify, passenger side or driver side?

I have a 2012 3500 ram 6.7 4 wheel service light is on

A brand new 2024 ram 2500 with 2500 miles on it mine is doing it now

Where is the actuator located?

What if it was red when it came &

I assume it happened because you never used it.
