i have some problems with my 82 monte carlo. my front left turn signal is all kinds of messed up. it will blink when the lights are off. and sometimes when the lights are on it will either not light up but blink or light up and not blink. any suggestions on what to do? ive already wired in new sockets and put new bulbs but that didnt help.

now to the braking. does anyone have any tips on replacing the master cylinder and booster pump? ive done it on my 87 F-150 but never on a passenger car. any help would be awesome
