Newbie here, this is my first post.
That having been said, I have a 2021 RAM 1500 Classic 2 years now and I'm creeping up to 35,000 miles.
I LOVE the truck. Enough about me.
I have (recently) become mildly to severely irritated with my RAM's cruise control because in the past month it has gone from occasionally to totally unresponsive to the cruise on/off (mostly "on") button on the steering wheel.
All other buttons were fulfilling their desired function, but getting that particular button to do what I wanted it to do when I wanted to utilize the feature it refused to do so and left me frustrated.
I'm 74yo and sometimes I get impatient with 'stuff'.
I joined this forum today and searched on cruise control and one of the suggestions was to re-seat the fuse (F81 if IRC) in the fuse block. The first thing I noticed upon opening the dust cover of the fuse block was that many of the fuses were sitting up in their mounting areas, guesstimating from 1/64" to maybe 1/32" or so. Not so much, but still.
So I pulled F81 with the yellow gripper so thoughtfully provided by the FCA design engineers and reseated said fuse to its maximum depth.
I also repeated the seating to maximum depth exercise on _many_ other fuses in the area.
There were MANY that had to be pushed down without forcing to maximum depth for their sockets.
Long story short, I hopped in the truck and made my usual Saturday 'rounds' of about 150 miles with maybe 5 or 6 stops and after every stop I would press the Cruise On button and lo & behold it worked flawlessly.
If you are fighting an intermittent to constant electrical issue, press all the fuses in the block to their maximum depth and try it again. Troubleshooting 101 that I had so unfortunately neglected.
Elementary, my dear Watsons. . . .
Thank y'all for being here. Saved me a trip to the dealer.
