okay so first of all my brake lights were on all the time when i had my lights on. and when i hit my brakes the corner lights in the front light up and the cluster lights up!!!! now the tails, cluster or corner lights dont come onat all when i turn on the head lights, just when i hit the brakes!!! need help!!!!

 

You might want to check all the grounds for your lights, a missing or disconnected ground will cause all kinds of mayhem with lighting.

Found out how true that was when a dodge neon came to get its lighting fixed, had one severed ground on the right brake light, and caused the blinkers to alternate with each other, change the brightness, and have the wrong lights come on when the brake pedal was pressed.

Later I found out this happened because he had put a bag of cement against the truck wiring, and pulled the ground out.

 

If the ground don't get you anywhere, check the turnsignal bulbs. They're 2-filament bulbs with 2 nubs on their base. If they're forced into the socket backwards, or 1-filament bulbs are put in there, it can cause that too.
