All of the problems you mention indicate one thing, you lost complete electrical power. A lot of times it is the ground cable. They do develop corrosion inside of the insulation where you can't see it. The cable will look great on the outside but bad inside. But the cause of the power lost can be any number of things. The battery could have any intermittent connection inside the case. Other ground cables can be bad. Whatever you do you need to concentrate on finding where the power loss in coming from. Take the battery to be tested and during the test, rock the battery like crazy to see if it will fail.

So? Are you asking for help or just bragging? If you want some help, then ask. All you did was make a statement. If you need help , we need details to give you any sort of help.

Some other thoughts here. The connectors under the fuse block in the engine bay may have corrosion and check the grounds for the ecm and bcm. Also check that the ecm and bcm connectors are fully seated. Maybe pull those connectors and check for corrosion then fully seat them.

Get that battery checked first. Keep in mind that you might have an intermittent in the battery. Something else to try is shaking the ground cable when you are having the problems(no start). Sounds like you do have a good head start.

Just about everything you list points to a ground issue. One big ground issue is corrosion build up INSIDE the ground cable usually at the battery. The cable may look great on the outside, but bad inside. Another clue you mentioned is moisture. Corrosion will affect an electrical system many many times worse than when dry. Another problem with the cable is bad crimps at the terminals. One ground point to check out are the ones at the forward left and right sides of the dash. I believe one is G218. I don't remember the other one. There are some videos on YouTube about them. You really should trust me on this. I have seen these type of issues here many times and in all or at least most cases it was a ground issue. The other times it ended up being the battery.

Quite possibly the climate controls glitched with the ground problem. Concentrate on the ground issue first, then worry about the a/c. It is MUCH more important that the steering is there vs a/c.

Every issue points to a bad ground or loose ground cable at the battery. Especially the driver's window issue. Guaranteed that means power was lost even if it was for a split second. Power steering is electronic so again you lost steering, you lost power.

Did you look ABOVE the glovebox?

Got it. I hadn't looked at them that close.

Check out the eBay item I listed above.

Check your cigarette lighter fuse. That one is where the OBD port gets its power.

Seems like a decent price. Depending on the condition of course.

Yea, they are mistaken. Those are for a double cab. If you can take a picture of the hardware, I believe I can tell you if they are the right ones. Those are the ones I put on my 2015 Silverado. Out of curiosity, how much are they asking?

Check out ebay item #182301959032. They have others too.

For some reason I can't see the pictures with Tapatalk. But to answer your question, no. Crew cab and double side steps are different lengths. The crew cab steps have four brackets per side and the double cab ones have three brackets. Make sure that you get all the bolts and clip-on nut plates as well as the plastic covers over the brackets. If I remember correctly there are 24 bolts and nut plates each. Also six plastic covers. The hardware is hard to find and when you do, they are expensive. At least they are if you have to get all of them.
