Sounds more complicated than my problem. Good luck!

Hmm, I have a small bird bath in my trunk because of the right tail
light lens leaking, but I don't see how that can affect the radio and
hazard flashers...

Pull the radio fuse and see what happens.

Not really. I've just learned to reverse without using the brakes

Are you sure it's the lens that's leaking?

It's funny that my car also had a bird bath on the right ... The water was
actually getting in under the boot (trunk) seal somehow. I just sealed a
rusty patch on the boot lid and the bird bath went away. No more soggy
luggage. But the birds were pissed off

It sounds like the ground might be corroded. Both the flasher circuit and
the radio use the same grounding point at G200, which is located just
above the brake pedal. It sounds like the hazzards are trying to find
their ground through the radio. Try cleaning up that grounding point.

That's a good point. Your flasher may be drawing excessive current.
Try replacing it.

Tried that, didn't work. I ended up rewiring the whole thing. Drew two
new wires from the battery( + and - ), which didn't help, and then took
the acc power from the brake light switch. Now everything works great
regardless of the hazard flashers. Of course, the lights behind the HV
controls quit while doing this, but that I can live with...

LOL. Exercising your e-brake is good.

I don't know. It's just that I've read that the lens frequently leaks,
so I assumed that was the problem. I don't really care though since the
lock is busted I never keep anything valuable in there anyway...
