hey how are you

1- the blower motor ,there a blower motor resistor & relay to check and also unplug blower motor passenger side under glove box & test for power.

2-the battery light is on and 4wd ? check battery for 12 volts

3- check alternator for charging 14 volts . at the battery with truck running and all loads on, headlights, radio,ac etc.. do you still get 14 plus volts

4- moving stering & it happened , i can tell you why this happened unless ,somewhere in the steering connection have a broken or loose wires

5- lets make sure voltage is good, if voltage is low the truck shuts down unnecessary systems to stay running

6-try a master reset for now & we go from there

Master reset Procedure

1- Disconect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You
