Wean I'm trying to purchase some things for the truck, it asks wat trim is it, North face, on road, wbh crew cab,base crew cab,? Please help

my interior lights will not come on. I checked the bulbs and they are ok. the front door lights work but the not the rear.

ai already had the rear rotors and brakes replaced but that didn't stop the noise

There is not really anything else to tell. Going by the owners manual , further damage may result if the remain on all of the time.

Cam sensor spark plugs wires coil crank sensor have all been changed. Just replaced the cats. And the p0306 is still coming up, what else could it be.?

recently the check engine light came on in my truck. The codes I scanned were p0740, p0758, p0785, p1860. Before I do it, I wanted to verify. This is where I'm getting confused. I checked the voltage at fuse "ign 0" key on, engine off and I get 12 volts. I pulled the trans pan (needed an oil and filter change anyway) and checked the solenoids. 19.5 ohms on 1-2 and 2-3 solenoids. I then pulled the plug and checked for voltage at the solenoids and have 12 volts. So, I'm at a loss. Do I change the switch hoping this is the cure and these trucks have issues with this. Or do I look further. I didn't get code po753. That's what's throwing me.

Started and drove fine in the morning - no indication of weak battery - two hours later, completely dead - nothing electrical works - battery still seems charged. Any suggestions?
