Hi when I put my left turnsignal on and hit my brake to slow down it blinks fast, but the second I let go of the brake it blinks normal. It is worse if I put my headlights on because when I hit my brake it goes out completely. Is there a way to tell if it is the switch?

p.s I almost forgot when I first flip my turn signal on my head lights flash out. Also when I have my headlights on and hit my brake my turnsignal goes on solid.

i priced out a switch and it is $150.

 

i have a similar problem my left front just wont work no matter how many bulbs i try it just wont work lol
