I never had the high brake light stay on dimm though, but try this first and lets see what it does.
On the older ones, wasn't there a ground on the drivers side taillight assembly that had the bad habit of becoming royally munged up?
Get a cheap volt/ohmmeter and measure from the outside of each socket to a known good chassis ground. You want zero ohms. Not even 0.5 ohm is good.
If you don't have a meter [get one, they pay for themselves at about $10] you can try using a heavy wire from the outside of the socket to chassis, but be careful so you don't let out any magic smoke.
BTW is there a constant, but not very loud, door buzzer sound?
I had a bulb in the CHMSL burn out, and the rear lights all went funny until I noticed and fixed it. The bulb sensor warning was on, but otherwise highly uninformative.
