97 Luminia brake/tail light problems

:1zhelp:My brake and tail lights are giving me problems. One day they work next day they don't. The rear window brake signal works fine. Someone suggested the brake light switch. Also when I turnon the headlights it causes the clockradio light to either dim or go off. I'm going to get someone to look at it tomorrow and would greatly appreciate any insight so I don't get ripped off and so I know if I'm goinna have to rob a bank to pay for this... Thanks in advance for ur help!

As for the clock/radio light when lights are turned on, there is a slide bar that moves vertically on left side of dash that brightens or dims dash lights. This also controls brightness of radio light.

If your window brake light works then it is not the brake switch. Most likely the signal switch in the steering column if its just your brake lights not working. The trouble could be something else though if your brake lights and tail lights not working

I must have been really tired when I was on last night. It's not a slide bar it's a wheel beside the light switch.
