2004 Ford Explorer 4 wheel drive wrench light on dash no power to ignition how do I fix

Check your hubs lift front end if wheel does not turn when locked in 4x4 then hubs are not engaging turn wheel by hand or a pipe wrench on drive shaft do not try power unless all wheels are lifted

Sounds like you have an electronic shift diff to put it in 2 or 4 wheel drive. You could have a bad position sensor, or shift motor/linkage problem. Unfortunately, unless you have the diagnostic tool to see which is the problem, it is best to take it too a good tranny shop.

Something you can do is to tap the 4/4 motor under drivers side on the back of transfer case with key on engine off. Have someone work the buttons as you gently tap the motor. Don't hit so hard as to dent it. Usually works.

Wrench light is a service due light and comes on every 10,000 klms. To reset light hold trip meter reset button in and turn on ignition whilst remaining hold on button for approx 10 seconds. spanner light will go out

First thing to do is have the computer scanned for trouble codes.

Clean the throttle body ,make sure you open it carefully and clean it very well..This usually fixes the problem

Why would or how would a vehicle know it was snowing,
and needed 4 wheel turned on?

Of coarse you have to select a button to turn it on or off

That said, it may not be working correctly,which is what your
parents told you!!

Its a simple fix....you need to have your lock cylnder in the steering column replaced.

The lights on the push button 4x4 wont light up .. you need to cut your wheel 80% to the right and then press the 4x4 button ..did this fix it?

Ok...several issues,and you won't believe this.......The 4 wheel drive is controlled by the Body computer,thats right,there is a computer that monitors and instructs Body functions like the door ajar sensors.Well,i just finished reading a technical article on a FORD that had no 4 wd,and the transfer case controller would not allow 4wd operation because the BODY computer sensed a door ajar,so 4wd operation was inhibited.They fixed the door ajar problem,a door sensor,the door ajar light went out on the dash,and the 4wd started working again...OK.....Check engine light is the vehicle computer that controls engine and transmission functions(PCM) has detected an error with a system.When this happens,the computer stores a diagnostic trouble code.Have the codes pulled with a scan tool or code reader.Repair the codes,and the Check Engine light will go out.The power windows,i honestly don't know,but HEY...2 out of 3 ain't bad!!
