200 Toyota Echo, tail lights do not work 7.5A fuse blows just replaced both head light assemblies flashers work dir work brake lights work

Your flasher is buzzing because it's a piezo instead of a flasher. I don't know how that would have been connected, but it is. Replace it with a flasher. The E brake light is on because the pull handle is still out just enough to connect it or it stays on because the antilock brake light is lit. Your dash and run lights have a blown fuse, headlights are on a separate fuse is why they still work. Water leaking from the roof shouldn't effect the electrical circuits, but most likely you have a wire or so crossed in the system.

Try disconnecting both tail lights replace the fuse and see if it blows...if it don't connect one at a time and see what happens...also check you third brake light...

fuses blow because of dead shorts or excess current draw
to blow a 15 amp fuse indicates a dead short
by disconnecting the rear lights , the problem is in something else you have replaced
could be a problem in the head light wiring

It can be faulty tail light bulb or its issue with tail light control switch or its wiring's are short.

Check the voltage at fuse slot of tail light.Do you receive 12 volt there.If not,then it says tail light switch is not receiving power supply.

Thanks.

you may have the wrong wires hooked into the switch. try testing the wires with an ohm meter and making sure they are both the positive wires. always disconnect the negative battery terminal before installing any electrical devices

the fuse is labled 'brake'

I would replace the fuse... and then have someone stand to the rear of the vehicle and watch the lights come on as I applied the brake... if the fuse blows again... note which tail light did NOT come on durring this test and replace the bulb.. it is grounding to itself and causing the short.

ck rear tail light sockets for cracks broken wires. and terminals in connectors are not touching

I assume that the 7.5 amp fuse blew again, yes? If so, it looks like you may have a locked up A/C compresser, or too much freon in the system (if somebody tried to add some to make the A/C come on). If the compressor is locking up, the engine will turn slow, at least until the drive belt or the fuse fails.
