Hi all-

New to the forum, so my apologies if I am in the wrong place for this.  I have a '21 Sierra 3500 Duramax that has the IMHO obnoxious plug in on the bumper that requires the proprietary cord from GMC that then plugs into an extension cord.  The "socket" part on the bumper that the cord plugs into has (A) lost the spring that keeps the cover closed when the cord isn't plugged in, and now (B) appears to be shorting out when the cord is plugged in, to the point that it has melted the rubber/plastic of the cord itself.  That might be a bit of a long winded way of saying that I need a new cord and to get a new socket to replace the one currently in the bumper.  I've scoured carparts.com, ebay, and a couple other sites and cannot figure out exactly what those parts are called or where I might source them.  Any suggestions welcome.  Thank you!!

Thanks for the reply. So, not something one could purchase on the internet?  I think the cord is salvageable, but the actual plug (in the bumper) does need to be replaced.  Seemed like something I could do myself if I could locate one.

Is the receptacle on the truck moulded onto the cord from it to the heater?

If so, is it the truck side cord assy that is required? 

Not sure it this is can or us pricing...  gmpartsdirectcom

(no doubt there are others that would show this item)

      Transmission Woes :-(

      By No1UKnow · Posted

      Hello All!   My 2019 Colorado 3.6 LT, 4WD Crew Cab has approximately 77,500 miles and I recently began experiencing the well-known transmission shudder between about 30 and 65 mph. The problem had worsened to the point that I could no longer attribute it to road conditions - and I had decided to bring the truck to the dealer - when recently, I experienced a sudden loss of power while driving at maybe 40 MPH. Several warning lights flashed, the “Check Stabilitrack” message appeared, and the Check Engine, Stabilitrack, and Traction Control icons remained illuminated. The truck regained driving power, but it stayed in a low gear with unusually high RPMs for the speed. (limp mode?) Because I was only about two miles from home, driving slowly, I was able to make it back and run an OBD-II scan, which showed fault codes U0101, P0700, and U0100. My next trip in the truck was to drive it to the dealer the following day. That trip began normally, but after about a mile I experienced another loss of power, along with the same warning lights and the same “Check Stabilitrack” message. As before the truck remained driveable, but again operated at an abnormally high RPM-to-speed ratio and seemed stuck in a single gear. About a mile later, the dashboard lit up once more, this time displaying “Check 4WD.” Soon after that, I arrived at the dealer. I have verified that the truck still has its original factory transmission fluid, which means it has never received the corrective fluid exchange outlined in GM Technical Service Bulletin #18-NA-355.  That was Thursday of last week and I've heard nothing yet from the dealer.    According to Technical Service Bulletin #18-NA-355 and the build date of my truck, my truck should have the newer LV fluid. I've done a little research and read something about a problem with the wiring harness as well.   Anyone have an insights into this situation?  Thank you!!

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.
