1994 Camry center brake light problem - Toyota Nation Forum : Toyota Car and Truck Forums

Jmmaroli · 08-03-2010, 08:53 PM

I recently noticed that the center brake light went out and the light on the dash for the brake lights came on. I changed the bulb and it still didn't work, so I used a voltmeter and found that I was getting around 12 volts when the brake was pressed, but the light did not come on. Would this be some sort of fuse or relay or what?

The new bulb may be bad.

I tried 2 new bulbs and they are the correct kind for the vehicle and are not dead.

Hmmmm. Well, it showing 12 volts is good. What about the resistance at that point?

Back in the trunk area is what is called a lamp failure sensor. They have been know to go bad. I would check that and see. The relay should have a part# of 89373-xxxxx depending on the VIN. If you PM me your VIN I can look up the correct one.

Good Luck.

Your getting power that's good but are you getting ground? How the inside of the socket look? Are the contacts actually contacting the bulb contacts? Check the simple stuff before checking the hard stuff. It won't be the failure sensor keeping the bulb from lighting. Remember there is power at the bulb, but not getting back to ground to complete the circuit. The only things in the way are the bulb itself, the socket, or the ground.

Take out the bulb and measure the outside of the socket to the center terminal with the brakes on. You probably do not have 12v there or the bulb would light up.

The outer part of the socket that surrounds the lamp should be connected to ground. Check the resistance from this to ground. If open, the circuit cannot be completed and the lamp will not light. If the outer ground is ok it must be the contact to the bulb. Try cleaning the contacts.

it is commonly referred to as an 1157 bulb.

Jmmaroli,

Did you ever get an answer? Both my brake lights have gone out.

thanks,
