Going to replace all 4 heater sensors, not sure where the knock sensors are or what they do and how to fix, and the knock sensor 2 low circuit input (Bank 2)what and where is that and what is the fix, any help is appreciated I have a helper that is kin to Google, Sir, Alexa and whatever the other names are and not getting anywhere

Old battery went completely dead, changed it and now I don't have any turn signal noise, door chime, and my radio isn't turning on. I checked every fuse possible and still nothing, any idea what could be the problem?

Obd 2 reader does not turn on when plugged in. What could be the reason?

Which fuse is for the obd port? Is it the cigarette lighter fuse?

Transmission is about 3 years old the rear end fell out going down the highway we got that replaced but now the transmission will only go from 1st gear to 2nd 3rd and then drive but if I go straight into drive it doesn't move but the rpms do it also reverses normally

Hey guys, were having some issues sith our 2004 5.3L silverado. Rear end blew 4 days ago, chamged that. Now since than its been reving and lagging when it shifts gears, and wont shift into OD/4th gear. Its got the 37:3 gear ratio for the rear end and. Now today, as we were pulling it out of the yard (it was still in first at the time) something make a loud TING CLANK sound and all of a sudden we have nothing but 1st 2nd and reverse gears. Not sure if this issue is due to a sensor, or if the tranny/ transfercase is not shot after the rear end let go last week. Any help is very appreciated. Im at a loss and this truck is becoming my worst nightmare. Thanks!!
