My 80 is constantly blowing the brake light fuse. Any suggestions on
where to start looking for the problem?

pull both your brake light globes out and replace the fuse.
get some one to depress the brake pedal and replace the globes one by one and at least you will know what side is causing the problem.
but as said above trailer pplugs are usually guilty.

The most likely cause is an intermittant short circuit.
Failing that however, fuses can fail if they or the fuse holder has slightly corroded or the holding mechanism is loose. Then, the resistance so introduced causes the clips (or whatever) to heat up and thermally conduct that heat to the fuse itself - thus lowering the current level at which it blows. This is not uncommon particularly with older vehicles.
Trust this may help
