Can anyone tell me where the High-Mounted Stoplight Relay is located on a 1992 Chevy Caprice? I have a new one to put in from AutoZone. They could not tell me where it is located..I tried Advance Auto and they could not tell me either. Stop light wont work but bulb is OK,the fuse is OK, the socket is OK and all other break lights work fine. Getting voltage to socket, then when bulb is installed, no voltage reading. I have also tried calling car dealerships but they have no idea either...oh and i have also checked repair manuals...they dont tell anything either....PLEASE SOMEONE...HELP ME!

IT IS NOT THE BULB...TRUST ME!...ive tried i dont know how many in there...and it is the right kind...I have tried the Chevy dealer..they dont know where it is...I have traced the wires..no luck there either...they are all working properly...Just need help finding this relay.

Your looking for something that does not exist. There is no seperate relay or circuit for the 3rd light on that car. I have seen the ground go bad on the housing itself. When you use a test light it will light indicating power because the test light is grounded. The housing itself is plastic and many times the mounting screws do not make a good ground or the grounding system rotten away. I would bet if the houseing was removed and the screw holes cleaned up with contact cleaner it would work again. We have see this time and time again with police cars and taxi cabs that are Chevy's. You might try a junk yard for a later model assembly. Some times the ground strap is rotted clean through look at each spot on the socket and make sure the ground is solid.

I wont even mention the bulb !!!
The problem could be to do with the earth for the high mount.
There could a fault in the glass thing holder. With the glass thing out there is a circuit, but once the glass thing is installed somehow the circuit is broken.
I wouldn't think there would be a relay for this brake light. Normally relays are used in circuits where there is high current.
Can you get hold of a wiring diagram for this vehicle? If so, find which is the power wire and test it with the earth probe to the car body. Then do a continuity test of the earth wire. I am assuming that you did your power test across the glass thing holder. Doing the test as I have described will test the validity of the holder.
Good luck.
Using a test light is bonza if you only want to see if there is power is in the circuit you are testing. In this case we need to use a multi meter to check the whole circuit.

Take your 12 volt test light and see if you can make it light up from the socket, with someone holding the brake as you already know.You said the wiring is good,the only way to know for certain is to use the light or a meter.
It is a quirk in the ground connection or possibly a defective bulb unless you happen to be dealing with a vehicle that has a high energy lamp module such as a Ford explorer.There is normally no relay,it's wired together with the other brake lights.

Sounds like you aren't getting much help from people. If you're close by I'll fix it for ya! If not, I'd check the wires with a test light. If you have running lights and then no brake, a filament could be out, if you have both, then the socket end of it, may just not be making contact, or it is really corroded in there. Spray some contact cleaner up in there and let dry and try again. You could also put some di-electric grease in there also to help keep a better contact. (running lights and brake lights, I'm thinking too much about trailers.)

I agree that it could be the bulb if you're getting voltage to the socket.
It could also be the ground, so make sure you're using the socket ground when you're testing the voltage.
If you're intent on finding where the relay is, I'd go down to a Chevy dealer and talk to someone in the Parts department and they could probably help you out.

If you have voltage across the contacts in the socket than you have the wrong bulb or you are putting it in wrong. I don't know who sold you a relay. Why would there be a relay on a light circuit ?
All stop lights are activated by the switch on the master cylinder.

It may not have a separate relay for that stoplight it's most likely part of the brake light circuit, you probably have a broken wire running to the light that's why it won't work, you should try and trace the wire to see where it goes

It's going to be identified as "Aux-Brake Light". Most times they are wired as part of the normal brake light system but if there is a relay it should be in the "Fuse/Relay Box" next to the brake light relay.

If you're getting voltage, then it HAS TO BE the bulb, or the bulb is not installed properly
