2002 town and country no dash lights at night
 

The only way I can see the speednometer , rpm etc guages at night is by flashlight...
Is there a fuse or whatever that powers the instrument panel lights..
The lights were working about a week ago..
Also my daughter had charged her cell phone about a week and half ago for about a hour and I had to get a jumpstart... She might have had the accessory key on also...
I had recently disconnected the positive terminal off the battery to clean it..
Been using the van every day for over a hour and it starts up okay and run a/c...
Any ideas?

turn the dimmer switch up? sorry got to check the basics first.
