electrical issue really strange

I recently went to the car wash for a detail and found the button to my stereo broken, it now acts like a toggle switch. now my dash lights come on when they want, my doors will lock if i play with the stereo on/off button and then you can not open the doors with the door handles you have to use the console button to unlock the doors. when the dash lights go out all the signals work just cant see them on form the dash and the stereo does not work at all. Can anyone give me a lead to what may be going on and how to fix???

Loose wiring somewhere. Might be impossible to find... Tackle them one by one. First take out the stereo and wiggle the wires a bit before reinstalling. Then take out your cluster and wiggle them about. Check for burnt marks on the contacts, etc.

Good luck.

Bad body control module?
