I have a 2014 GMC Sierra 1500 5.3 2WD 4 door. Only cold air coming out the vents. So i pulled the glove boxes out so I could see the blend door actuator. I could see the clip wasn't connected to the actuator. So I connected to wire clip to ghe actuator,  and was excited to see if maybe I had found my no heat issue. But, now my teuck won't crank. Turn the key, 1 click and nothing. Ive checked every fuse. All good. I even jumped the starter relay. The truck would turn over but wouldn't start. I'm clueless.

No battery is fully charged. Also I jumped the starter relay and the starter engaged and turned the truck over but it wouldn't start. I forgot to mention,  for some reason I've got a message on my dash saying stabilitrac disengaged or something like that and steering assist limited. Never had that before now.

Behind the glove box is the "Brain " of the truck. It has a few plugs going into it. I would make sure you did not dislodge something when you was working on the blend door.

if you accidentally loosend the connector on the human interface module, you wont be able to start the truck.

      I'm also waiting to see if they confirm Apple CarPlay, because I'm not interested in subscription fees just to use the hardware I already purchased.    In closeups it looks like it gets the Colorado/Canyon center screen based headlight controls which I despise. They also appear to lose all the hard switches for functions like seat heating and cooling, parking sensors, lane control, traction control, etc. which means they're all screen/menu based, so verdict is out on how well those will work with gloves or wet/dirty hands.  Admittedly they don't show the left knee area of the dash, but I don't see hard switches for locker control on the ZR2, and the "mode" switch appears to eliminate the rotary dial with a quick way to access tow/haul.  My 2021 has had multiple screen failures and at times the screen just locks up, goes black, or reboots while driving even after replacement, so loosing the ability to access many of these functions, especially lighting control would be pretty frustrating.   There aren't enough photos or detailed trim details other than one mention of "available microfiber trim" to confirm, but the use of microfiber on the seats and or center console is a deal killer for me.  Just because you drive a ZR2 or High Country, doesn't mean you don't work out of it, and that material is difficult at best to keep clean and looking decent.   Lexus and several other brands are using it on seats, dash, and door panels now, I assume as a cost and weight saving measure,  and it looks horrible 1-2 years into ownership.  I see what appears to be piano black on the doors and center console in some photos, which also has no place in ANY vehicle in my opinion because it mars and scratches too easily, especially for a truck.  Will be interesting to see what GMC comes out with when the Sierra is released as far as materials go.

      Im a fan.  Simply moving the screen up helps the look of the interior.  I feel like GM dropped the ball on the current gen having the screen not at the same level as the top of the gauge cluster.  The GMCs look better with the vents above the screen to close that gap.

      OCI, not when but why?

      I hear you, its just not something one would even think of that the new oil in the container isn't filtered to a spec one would expect it to be.    As to a passenger vehicle theme and the maintenance requirement to meet to ensure a warranty is honored, these days with claims of life time transmission fluid on some models and the limited amount of oil changes that would bring one to the end of the factory warranty, that sells vehicles for those that like to hear "easy care maintenance free", but the manufacturer certainly knows different as to what that more than likely means for the longevity of some of the components if given that minimum spec maintenance. Then again I imagine there are a fair number of people that really don't care as long the vehicle gets them a certain number of years down the road because they are the type that want the next new thing, new and improved ... more bells and crap etc on the new one on the show room floor. Manufacturers have learned the phycological game to entice the customer out of their money !

      Why soooooo many screens? Shall we just replace the windshield with a large plasma?!?!? Besides that I like the looks. And they added back the additional door cubbies,    No SS???
