Tail lights, brake lamps and radio speakers are inoperative. Park interlock works and brake light switch has power and is operative. I do not know where the brake relay is. Can you tell me where the brake relay is located on this car and where the common ground for these systems is located?
Hiya
cars dont have relays for brake lights as its too low power.
If you have power across the switch you may want to check the connections to the bulb holders and then check the bulbs themselves.
If no power at bulb holders you need to check the loom which, unless you have had some welding or similar disruption would be very odd.
Check for a good earth at rear bulb holders too, quite oftena poor earth will cause many faults.

if that doesn't help, you might want to check the bulbs. the damage might have shorted which burned out the bulbs. but you do have one wire that runs to the rear and splits off to the tail lights. the wire should run back to the head light switch via a fuse. the headlights have its own relay. but i hope it is just a fuse.

I have had this problem with my wifes 92 celica.....the brake sensor that is attached to the brake pedal was the problem....I took it off and cleaned it up and puff it worked like a charm. The sensor is located on the brake pedal arm about midway up. I hope it help you out.

Before going ahead and spending money on a new module, test it first. The module is located under the steering column. You'll find a Brown wire on one of the connectors (i just looked at a wire diagram). Do no disconnect anything. Back probe the brown wire, which is the power feed to your park lights. With the lights off, there should be 0 volts on you voltmeter. Turn the park lamps on, There should be 12V. If there is not 12V, disconnect the connector and try to check voltage at the pin that feeds to the brown wire, if still not 12V, replace the module. If you do get 12V, then module is ok, find where the 12v is being dropped before making it to the lamps.

Even though the relay is activated,I assumed you checked the out put?Also,You checked the voltage at the light sockets?With a meter,or test light ,check the fuse for the cluster lps,adjust them to dim,and to bright,the meter should act accordingly on the fuse.If it does not,replace the dimmer control,or head light switch,witch ever controls them.This may allow continuity to the tail lights as well.If the fuse is dead for the cluster lights,replacing the dimmer control,or head light switch will solve the problem,or,from another fuse ,supply voltage to the cluster lp fuse,one that is only hot with the key on,cause if you do this the dash lights will come on,every time you run the vehicle,day,or night.
