Overhead Console Lights w/ Wiper

Anyone else have their overhead console lights flicker every now and then when the wiper is turned on?

Just noticed it on a road trip while it was foggy and enough water was accumulating for me to do a single wipe every now and then.

I'm thinking it's a short somewhere but i'm not sure.

 

No but when my lights are on and the fan is on high the fan slows down when I pull up to a stop sign.

I don't think the alternators on these trucks are very good.

 

I was wondering the same thing. Was stopped the other night with my 4 way flashers on and noticed my interior lights dimmed when they flashed.
