Whenever the car is receiving power every single light in the cabin will randomly go out for no reason, except the handbrake, turn signals, and some other dash warning lights; those never go out.
Then sometimes they turn back on randomly if I smack the dash near the dimmer switch, hit a bump, or sometimes they just come back on while driving for no reason at all.
I visually inspected what appeared to be the correct fuse several months back and it didn't look blown. This issue has been going on for ages and I'm sick and tired of it.
Any help would be greatly appreciated.

 

which chassis/trim do you have? this sounds a lot like a ground issue.

 

It's a 99 LX.

 

pull off all your grounds and clean them, retigthen

 

Obviously the dimmer switch.

 

What makes you think it's the dimmer switch? It functions totally normally whenever the lights decide to turn on.

 

Dimmer switch powers the lights in the cluster. Unplug it and you'll see they don't work.

 

they did not read your post closely.

if you only mentioned the dash lights I'd agree. but since the interior lights are included in your original statement, it has to be a ground under the dash. or a fuse that's not properly seated or the connections are burned.

 

Check fuse #43 for the lights it's a 7.5amp, remove and reinstall it.. could have a poor connection.
