couple issues, lights, gear selector, steering

hello I have a 05 automatic that just started having several different issues.

1st all the dash lights and dome light quit working and there was a odd smell that happened around the same time.
I did the splice box fix and still not working. the splice box was not burnt or melted, but I cut it out and soldered the wires like instructed.

2nd the car will now only start when I put the gear selector in neutral, and the other day it started rolling after I put it in PARK.

3rd the other day as I was driving my steering wheel became very hard to turn then got a little better as I drove.

these all happened within 2 weeks of each other.

ANY HELP WOULD BE GREATLY APPRECIATED,
Bigrig

This is my daughters car , I am a Tractor trailer Operator and work away from home so all the info I gave was what she told me was wrong.


2nd thing fixed: well I took my plastic console off to get to the gear selector and found that the nut holding the linkage rod to the gear selector rod had come loose. So after checking the adjustments I tightened nut and it starts in PARK again and shifts into all gears just fine.

3rd thing maybe fixed will find out after epoxy cures: I found the power steering resivior bottle was broken where the bolt holds it secure. I cleaned it up and used some epoxy I had , there is a 12 hour full curing time so time will tell. I got one ordered just in case , it's a Chevrolet Stealer only part, 69.00.

STILL NEED SOME HELP ON THE DASH LIGHT PROBLEM any Ideas?
