When I turn the key on, the dashboard lights but no crank, no sound. If I keep trying it usually starts after several tries. On a few occasions it cranked Just as I was releasing the key from fully turned. It was a week before it happened again, then worked okay for a month. I brought it to my usual repair shop but they couldn’t diagnose it because it started every time they tried. Drove okay for another month. Next time it failed I had it towed to the same shop. They have been trying it for a week but it starts every time they do.

Any thoughts about what could be causing this? Next time it fails I plan to take it to the dealer. 2016 Sierra 1500

So I just started having an issue or my AC is blowing cold, but then starts to blow warm, but then starts to blow cold again. I noticed my cooling fans only work when my AC is on, but never engages to the high speed. It should after reaching a certain temperature. I had someone use a scanner to automatically turn on the fans to high and they do work but at the same time this happens my back, A/C doesn’t blow at all no air comes out. I change the sensor that’s on the line. No change. The guy who scanned it said he was getting a bunch of HVAC issues. But also got a code that said no communication with the Telematic control module. He said that could be the issue that’s causing the fan to not turn on high and for the back fan not to work at all but everything I’ve seen online says there’s no correlation. I don’t wanna buy the module if there’s no correlation any help would be great.

6.2L V8
187k miles


Been having some engine issues.
Replaced all 8 spark plugs, wires, coils.

Now at idle, no significant shaking.
Fuel System 1 and 2 status move to OL-Fault after a minute or so
Then traction control and stability lights come on
Followed by flashing check engine - P0300 multiple misfires

Check each cylinder report - 0 misfires on all

Get the RPMs to 2000 and the Fuel status 1 and 2 both go to CL.
The engine light goes away
The traction and stability lights go away

Drives fine. No noticeable issues other than the beeping an annoying flashing lights.

Issue seems to be air intake or fuel mix or sensors.

Short term fuel trim stays at 0.0% until the RPMs are up. Open loop fault?

O2 sensors seem sluggish - move between 0.9v and 0.2v.

MAF 0.78 to 0.83 pounds/min at idle
MAF 2.5 pounds/min at 2000 RPM

All the problems are at idle. I cleaned the throttle body, added fuel, did a battery reset. What else?

I threw all this into AI and it says I need to replace the front two O2 sensors. But what do humans think?
