Has anyone changed their door handles yet?

 

I have two problems. I bought some LTZ chrome door handles. I noticed when I took off the door and the door panel that the 4 wires from the LTZ door handles had a purple where mine had a brown. Didn’t think this would matter much, but when I tried to install them, the buttons don’t work. Can I just flash the ECU at the dealer? Has anybody changed doorhandles with buttons?

 

The second problem is honestly, I can’t get the damn thing back on! There’s a video on YouTube of a simple screw in/screw out torx bolt. But mine will not catch the door handle for some reason? I feel like I’m going crazy. What the heck am I doing wrong? Anyone?

Are you sure your new handles are for 2019 and not the K2? There is no “just flash the ecu” to get something to work. It’s not like they just check a box and something gets turned on. That, and most dealers don’t want to mess with programming customer added features.

As far as the handle goes, try using a small pick tool to grab the lever inside the handle opening and pull it out towards the outside of the vehicle, then slip the handle in and it will grab. They can be tricky sometimes to have the handle grab the lever.

They must be for the '19. OP says button doesn't work. The K2 didn't have the handle lock/unlock door handle button feature. I've changed several handles on my K2's and purchased a 3 piece pick set (orange handle) from Harbor Freight. A must to install as said above.

Yes, they were ordered from GM, LTZ vin number. 2019 chrome handles. I’m trying to put them on a LT Trail boss. Fit fine. Function is normal. They plug into the female in the harness perfectly and clip in securely. Buttons just don’t work. I hear a very high pitched “electronics” kind of noise For half a second or so (I know that is a dumb description but that’s the only way I can describe it) under the dash/in the truck when I push the button. But nothing happens.

I had a '16 SLE and purchased SLT/Denali mirrors with turns and puddle lights; Everything plugged in but they never worked. Tried more than 1 set. It was all in the BCM.

That’s kind of what I figured unfortunately. These dang things are expensive too!

On a separate note, I hadn’t watched a 15-18 video yet. And after watching one just now, the fishing string trick should work perfectly for what I’m trying to describe.

Yea seen the fishing string method. Both work. I had good luck with the pick. So what you gonna do about handles now?

i used .095 line from my string trimmer to get the handles back on my 16 LT.  I swapped them out for Escalade handles.  

 

For your wires, I would see if you can find the wiring diagram for the two door handles.  you might have to just re-pin the plug

Not sure. I would hate to lose the function of the passive entry buttons. I got used to it and really like it a lot. I’ll have to research the wiring more.

I actually ended up getting it to work with the pick method tonight. I kinda feel like a dummy now for asking the question. Should have just watched a few more YouTube videos.

 

Thats a great idea about wiring. It’s a bitch to get it all apart, but if I figure anything more out I will be sure to post update. For anyone who is wondering.

Check with service mgr. to see if he can figure it out. If not they make some really nice chrome covers that stick with 3M and have the passive hole. An option.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
