Volvo Repair: Dead Brake Lights, volvo 740, loose ground

Question
Mr.Easler lll,

I own a 91 Volvo 740 turbo sedan.  All the brake lights have gone out on my car except one light in the bottom right corner of my car.  I've checked the fuses and replaced all the bulbs.  I was wondering if you had any insight into what might be wrong with my car, and how I can fix it.
Please help me.

Thank you,

Jennifer :-)

Answer
if one brake light works the problem has to be in the taillight,the bulbs or in the wiring somewhere.there may be a loose ground on the taillight that does not work.check thsat the ground wire is tight.I would also check the wiring connector at the taillight to be sure it is not corroded.
