No break lights, 1999 villager

check sensor switch at the brake reservoir

Check the brake switch located above the brake pedal. There should be power on one wire all the time and power on another with the brake pedal depressed. If there is no power with the pedal depressed than the switch is bad.

Also check for broken wires at the switch.

Make sure the bulbs are good. I have run into all the bulbs burned out more than once.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

it sounds like a ground problem...sounds like the ground is trying to go through the bulbs to make connection....check all ground wires battery, engine and rear frame...

CHECK TAIL LIGHT BULBS.IF BULBS CHECK OUT GOOD PROBLEM COULD BE CORRODED BULB SOCKETS OR BROKEN LOOSE WIRE IN CIRCUIT.

Very common problem in Camry's.The wiring harness to the trunk running down the driver side hinge become pinched and or flexed so much they break.

There may be an adjustment on the switch, not sure, but hope it helps a little

check your wiring harness to breaks and shorts also check to see if water is getting into the turn signal lense through a crack

Most likely a short in your break line. You might also check the brake switch, but I would think if the break switch was going, it you wouldn't even have the third lite working...

Do you know if the brake light bulbs are working? (are the bulbs good?). (the bulbs have two parts, one for brake lights the other for running lights)
If the third brake light bulb is working the brake lights should be with good light bulbs.

Do you own a test light? Check for power at wires behind socket? Clean socket good , check contact spots for bulb & clean any rusty side of the socket with emery cloth, or sandpaper, for good contact also.
