2000 towncar..brakes lights don't function

[tjsw]

the fuse is fine but none of the brake lights go on...have replaced the brake light switch but that did not solve the problem

First, test the fuses with a meter or test lamp. 20A Fuse #10 & 20A Fuse #22.

We do this kind of diagnosis allot and many times the OP comes back with.. "thanks for the million suggestions, I finally tested that good fuse, it was bad"

Next, verify the bulbs are actually working, yes they could all be blown. The High-mount (3rd brake light) bulbs need testing too.

Here's the detailed, step by step diagnosis procedure:

Sorry, I just noticed I hadn't made that link 'public'; it's fixed now. My Firefox doesn't like it, but IE does

While you are digging around back there I would check all the wiring to the lamps to ensure there are no brakes or frays.

All Brake lights are design in parallel and sharing 12volts.
If a light bulb go's bad replace ASAP,or the others will follow!
Just like a head light when it go's out,the other will get brighter and
burn premature.
