2000 grand cherokee, left brake light will come on if head lights are OFF,
will NOT come if head lights are ON, right side works normally ???

 

A bad bulb will cause that.

I also have weird brake light problem. 98 Cherokee (XJ), sometimes, and
it seems to be when the vehicle has been running a while, the right
rear directional signal light will go on when the left rear directional
signal light goes on.
(ie, I signal left, and both the left-rear and right-rear directionals
flash together, as if the hazard flashers were on.)
Any ideas?

Broken filament in the brake lamp bulb. When the Lights are off, the brake
lamp grounds through the lighting circuit. The ground source goes away when
you switch the Lights on.
