Couple questions. Is it a common thing that on GM trucks you have to slam the tailgate shut to get them to close? Its like everyone i see you have too. I want to fix this but have no idea where to start, is there something that binds that will not allow them to close? Also does anyone have a blow up of the parts within the tailgate so that I can see how it works. Thanks in advance

Never seen that on the GMT800-GMT900's...

 

Are those aircraft cable straps binding (the ones that support the gate when it's down)? On my GMT800 I sometimes had them fold out so they would get caught when I closed the gate. If they folding in like they are supposed to, mine closes like a car door. Before I found that, I slammed it a couple of times, then it creased them, so I had to change them out.

No the cables dont seem to be binding at all. It looks like the latch is not setting, almost like the handle mechanism is not releasing(like you are holding the handle open). If you have a blow up diagram I want to see if something is corroded or not releasing properly.

My '07 did that. I brought it in for service, they replaced the latch(es).

Closes nice and easy now.

Welcome hrspwr.

I'd suggest a liberal application of WD40 (or equivalent) around both latches / orifices, as well as tailgate handle linkage (remove handle bezel, get a good light, spray linkage & handle pivot points).

I prefer white lithium grease myself but I agree w/ the above....lube it up and see what happens.

I found the issue, it was the handle. There is that pivot point that when you open the handle it pulls the two arms that go to the latches on the ends of the tailgate. That pivot was a little rusty and would not the latches return. Little bit of WD and a good old hammer did the trick, lol. Closes like a dream. Thanks guys.

Looks like i'll have to take the handle apart on mine...I've had the same problem too won't always catch if you close it softly but if you slam it catches every time...I found that wd 40 works but only temperory

Do not use grease on the linkage as it collects dirt and gums up the linkage. Use WD-40 or Dryslide, neither collect dirt dust.

Good point. Silicone Spray works great as well. Once the carrier evaporates, you'll see the benefit.

Don't use WD-40.... unless you use it to wash out the rust formation, then follow up with a lubricant. WD-40 is a water displacement formula. When it flashes dry it will have washed all of your lubricant away. You should wash it out and put some white lithium lube or door ease back. Edgewise you will be back soon.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.

      “It should be recognized, however, that there becomes a point where fuel economy oils do not make much economic sense for the end consumer—we talk about a fuel saving of ~€100 compared to a risk of €1000 Euros if the oil is too thin and causes increased engine wear rates. However, the benefit of these oils accrues to the car manufacturers. If their vehicles can save 1–2% fuel by using a special fuel economy lubricant, then that OEM can drastically reduce the amount of fines they need to pay.”   I liked this and the following paragraph as well but it’s really only touching the beginning of the benefits OEMs see from spec’ing these oils. After you factor in “out of warranty” service work and new car sales when these engines fail before their time, it’s a good racket for them. Just because you're paranoid doesn't mean they're not out to get you!
