Flasher issues Options

[carking1996]

Hi I've recently got my brake lights, turn signals, and hazards working again a couple weeks ago. I found out that the PO wired the fuel pump to the fuse panel where the wire for the brakelights/cluster/etc wires are supposed to go. So, I got a double split terminal and put both of them on that fuse, along with replacing the fuse with a 20 to prevent burning it.

Now, the car runs great. But, the middle brake light bulb turns on when the lights are on, and when the turn signal is on (with the car off), only on the drivers side, which isn't supposed to happen, and no hazards work at all, along with no turn signal on when the key is on.

The driver side brake light also no longer works. I checked and checked, behind the dash, under the dash, the tail light wiring, no burned wires or short that I can see, no fuses burned. but I did notice the turn signals worked briefly before melting my flasher relay, now they don't work at all again.

Any leads of where to look or what would be causing this?
