Instrument Panel Lights Dim

My 72 Swinger has VERY dim instrument panel light, and the A/C - heater lights are out. Any experts out there that can tell me how to fix these issues? Thanks in advance!

RedSwinger,
I am truly sorry for misinforming you. I never meant any harm. I was just trying to help.
I probibly won't be doing any helping anymore because I'm such a dumb Ace!

I am sorry too for posts. Didn't mean to take over your thread.
I will humbly crawl into my hole now.

If I caused harm to your boards by you following my instructions, PM me let me know and I will get different boards for you.
Again, I am sorry.
John.
