climate control lights blink

ok if anyone remember when i put my alpine cd player in, how my climate control lights and my dash lights stopped working? Well tonight i got in my car and let it warm up for a sec and tapped the brake and my climate control lights flashed along with my hazard and defroster button lights. So the blubs and all are fine but i think its a loose wire or fuse or something. It didnt do it constantly but just a lil bit when i first started driving and then it stopped doin it. It would blink after about waiting a min between tries. Im not sure what it means, maybe its a power short or something.

weird, same thing on my car. If you press the brakes really hard and fast everything will blink. Weird!

well mine dont work for the most part they just worked for a blink. my dad things its a bad ground from when we put in the stereo.

yeah the ground from my engine to the car is almost deteriorated so we need a new ground - i was thinking of getting a grounding hit
