It's been a few days since this started, the lights in the cluster started to go off and on, and now, the light won't turn on at all... Also, I think it started at the same time as the light problem did, theres a clicking sound around the cluster area, two small clicking, then a long pause and it starts again...
Would that just be a loose cable making the lights not turning on anymore?
Thanks for the help

edit: also, the brake light won't light up with the light switch on, If I press the brake pedal, they will go on, but during night driving, they are completely off, my light switch must be working because my headlight turn on as they should be...

I have an 86 gxl if it matters, thanks

 

Sounds like a burned switch to me, but I'm not 100%. Any easy way to tell is to look at the plug and see what it looks like. Most likely it will be charred/black at some spade.
