I swapped out my original DL3 mirros with the Kool Vue tow mirrors on my 07 2500HD Silverado. Now when I unlock the truck with the key fob the new mirrors go whacky. I've heard this even happens on the GM tow mirrors when swapping out. I've had to turn off the memory function recall in the DIC. Does the BCM programming need to be updated to tell the truck the mirrors are different or can the mirror recall be disabled but leave the seat & pedal memory functions intact?

I know I'm bringing up a two month old post, but just installed towing mirrors on my SLT, and having the same problem?

 

Any resolution? Do they really have to go to GM for programming?

Yeah, they probably have a totally different resistance on the motors, so when the memory function tells them to go one place they end up in another, than it tries to tell them to go back...and the same thing happens...and so on.

      The Peckish Synapse

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.

      New Duramax rumor?

      New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.

      first oil change - 2026 2500HD gas

      I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.

      I would never do anything but lithium.   If the vehicle is stored, just turn the disconnect off. My batteries are completely disconnected form everything in the trailer when my disconnect is off. Trailers don't always come that way as some still keep the CO/LPG monitor on. When mine is off...it is off.   As far as storage temps, LiFePO4 are good down to -20°C. I would store them in a heated place if it goes below that. You can also get heating mats with a thermostat if power is available.   The way the heaters work, if it's below 0°C, if a charge comes in, it is directed entirely to the heater until the battery gets above 0°C and then it allows the charge to go to the battery.   For my Android tablet I use as a display, I can move it inside my house if I was ever in an area that got super cold.
