Turn Signal Issue when Towing

I just purchased our 2019 Chevy Silverado LT 1500 4x4. It has the tow package on it. I connected it to our 2015 Lance trailer for the first time when I was getting it back from it's seasonal check-up. I ran the lights check on the info system. No driver side turn signal error for the trailer. We just sold our 2010 Tundra and had no issues. So the trailer shop brought out the test equipment and connected to the trailers cable, all lights worked. We then checked the truck all lights worked. Hooked it back up, no driver turn signal on the trailer. So the shop guy grabbed his truck, a Ram. Hooked up and all lights were fine. Next, took everything to the Chevy dealership. They hooked up another 2019 truck, same no left turn signal on the trailer. He then grabs his 2013 Yukon and everything works fine. Any help would be great here. Everything works separately but when connected to the new trucks no left turn signal on the trailer. What the heck?

maybe your truck is doing some stupid current check on the circuit and thinks there's a problem because the LED doesn't use quite enough power for the truck to tell it's working.  try swapping in a old bulb-style light for the LED one and see if it works...

Thank you for the suggestion seems strange because all of the lights are LED only this one doesn't work. See sealed light assembly on the back of the Lance trailer you cannot easily be swapped out for a standard. This really should not be an issue. I even tried changing my trailer selection in the infotainment and got nothing. Goes in next Saturday so I will mention your suggestion if they can't figure it out.

Alternately, you could try inserting a resistor in parallel with the light in question somewhere else in the circuit (my trailer has a 7-post patch panel thing I could use for something like this), similar to what you do for eliminating that 'fast-flash' when switching older trucks from bulbs to led's.  That also makes the circuit use more power, and doesn't affect how much power the light gets (so it still gets as much power as it needs to work).

google "fast flash resistor led".  lots of info, videos/images showing sample resistors, how they install.

If you don't have a patch panel thingy like I have on my trailer, you can (after getting an appropriate resistor), test it by disassembling the plug to the trailer, install the resistor between the ground pin and the pin for the light that doesn't work right (making sure it doesn't touch any other pins, and then insert the plug into the socket on your truck (with the plug still disassembled, making sure it's the right orientation) and test if the light works then.

 

If you aren't comfortable doing this, get a shop to try it.

Tier problem sound similar to mine. There is a fuse box under the hood that provides power for you left and your right brake lights using a different fuse for each light. I have a 2009 Avalanche. It could be worth wild to check.

Did you figure this out?

I have a trailer with all LED lights and it works fine with my 2019 Trailboss LT . I sometimes get the "check trailer lights" warning when hauling it the DIC. Even with the warning it still works without issue.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
