The brake lights will not work although all of the taillights function properly including turn signals and reverse lights. I have already replaced the brake light switch and the fuse appears to be okay. What next?

Please recheck the 20 Amp fuse marked "Stop" in the fuse box. Then check that you have 12 volts present at the green/black wire at the brake light switch. With the brake pedal pressed you should have power at the green /white wire at the switch.
Next there is a junction where the brake light switch wire sends power to the rear brake lights. With the brake pedal depressed there should be 12 volts at the green white wire at the connector found in the left rear panel somewhere between the fuel filler lid and rear left tail light, it is at this connector the power splits and feeds the tree rear brake lights.

Thank you for this post. I used it today to troubleshoot why my right brake light did not come on when the brake pedal was pressed. Using the information you provided I was able to determine everything up to the connector at the taillight was working properly. I had a bent terminal on the brake light socket. Thank you!

Mine also had a weak terminal connection in the right side that the wires plug into.

I see a tail light relay available Airtex 1R1477 should be available at your local auto parts store, Call ahead because only some stores carry Airtex brand.
