Why does my brake light not work when I apply my brakes?

I drive a 00 honda civic DX coupe. When I turn on my left signal and don't stop on the brakes the signal is fine but when I put pressure on the brakes while the signal is on my turn signal won't flash. While I'm driving without the turn signal on when I brake the turn signal lights up dimly on my dash. The right turn signal works perfect. What could be the problem can someone give me a step by step on how to fix it or a link on how to fix it. I don't have money to go to a shop ATM so I would rather do this myself.

Could be a bad ground on the bulb socket.

watch this might be it can solve your problem.

Because it's broken OB V O SLEE
