I just recently purchased a new 2020 Chevy Silverado 1500 Texas Edition. The truck came with the standard halogen brake lights. I purchased some new LED OEM taillights and thought it would be plug and play but quickly realized that’s not the case. The lights will illuminate but when I turn on the signal it flashes normal for about five seconds and then starts flashing rapidly. The dash screen also reads that there is an issue with turn signal. How can this be fixed? Thanks!!

They usually would have to install resistors to stop that

I put LED taillights on as well (With pre installed resistors on them) all lights work fine as well, but when I use the turn signal the same thing happens. If you fixxed this issue how did you do it. I have explored the internet for months on this issue and cannot find a fix!

2020 Chevy Silverado 2500HD Diesel . Had a cracked left rear tail light Lense. Filled with water after so long.

One day noticed tail light was out. Turn signal is hyperflashing. Removed tail light assembly unplugged it Drained water, tail light working but dim. ( These are the factory LED P.O.S.'s) One plug terminal on the back with one bulb which is the backup light. Turn signal still hyper flashing. Replaced tail light assembly and blinker still Hyper flashing 

Now what?  Disconnect batts and try and rebot system?

 

BTW, watch out when purcahsing these tail light,  advertising will tell you LED ,  however, when you receive it, its ythe halogen bulbs type. 

 

What a F.N.M 

 

Please advise 

 

Thanks Dave

You stated that you replaced the taillight assembly. Was the taillight assy. O.E.M. or purchased from amazon or ebay?

I heard from someone that the 19 and up trucks that have LED's have a heavy duty trailer flasher installed and for some reason the resistors do not work.

      The Peckish Synapse

      Well that book won't sell many copies. Taking ones right foot off the loud pedal never gets applause. Funny really, It isn't that people don't know what to do...they just don't want to do it. But they will complain about it. About bad craftsmanship, about the cost of fuel, about the cost of part and repairs and mainly they complain that the solution while still possible isn't one they are willing to do.    I observe this daily. 'Gas cost to much!", they wail, while they mat it passing at 80+ mpg and scoot down the road like gas cost a dime a gallon. Then complain about the few that will lift and save both fuel and iron like they are owed and own the road.    Good thing they haven't an ounce of influence on my equipment. The rest I just laugh at. Stupid is as stupid does, right Forest?

      Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      By TrueBlue · Posted

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.
