Need help here, key will not turn all the way to remove and with key on there is always a steady tone from mfu

I did a search, tried disasembly of shifter handle to tighten the nut inside, no help there , the shifter is in park, the trans is in park, crawled under to check

Raining and need this fixed

 

Also drivers door pin switch now inop and the dome lite turns off immediate when you open other doors

Guessing MFU is bad? I hear it click when I try to turn key to remove

 

Ran MFU check, sequence ran as it should?.? Ideas?

 

What is the difference between the auto and manual ignition tumbler? I have auto trans, but a spare manual tumbler

Well took off the column covers unplugged a white plug just above the key and now key comes out, the connector goes to the lite ring and ? But everything works so good for now till I have more time later

I do still have the audible tone with key on

 

OK I sort of figured out the noise from mfu by mistake

I tried going into low and it will not move, now stuck in 4 hi, but pulled back on that shifter, sound stopped, push forward sound comes back, did this several times same results

So .... guessing it is an alarm saying you are not in 4 hi all the way but trans is in drive? Or hey dummy I will not let you out of 4 hi unless trans is in p/n?

Either way I have working diff lock but stuck in 4 hi, guess I should have gutted the plunger with trans out ugh
