I need to find the fuse location for brake lights particularly the left to check if the fuse is good. Service indicated that the whole left rear unit must be replaced, (est. $350)

try to go step by step to solve the problem.First check if any fuse for lights is blown,if so replace it with new one on same capacity. Second check the rear bulbs if are okey or not renew accordingly. For brake lights even more proceed on brake lights switch which is always located under the dashboard on driver's side above the brakes pedal. even more check for the rear lights unit if are well the connectors connected .

Aren't your brake lights and turn signal lights on the same bulb, same filament? Recheck the bulb in the rear, as the rapid blinking is an indication of a burnt out bulb. If the bulb is the correct one and is good, check the connector and socket at the housing for a loose or poor connection.

When you are talking about "indicators" we could assuming that your are refer about signal lights. This work with "flashers" devices.

For 1996 Audi A4 2.8L SFI 6cyl the Flasher is located in front seating area, driver side, under dash, behind dash lower panel, mounted above driver side of steering column.

About generic fuses, open the driver side door. Remove panel on left side of dash. Fuse box is behind panel:

Check fuse f3 located in fascia fuse box,below steering wheel just above data link connection 15AMP
Fuse under bonnet f7 also connected to dash/rear lights,but if this blows you would have no indicators as well
good luck barry

The high mount brake light has its own fuse, so check that first. The high mount bulb is generally a stabdard type (there may be more than one bulb) or you can replace with an LED. As for the left rear bulbs not working when depressing brake pedal, check the bulbs again for any spring that may be broken. If the bulbs are still good, make sure there is sufficient contact with the socket. If still not working, have someone check it out further.

Fuse number 7 (15A, Horn Stop) in the under hood box should be your brake lights. If you are referring to your high mount brake light as the third light, I believe they work on the same fuse.
I would check the bulbs, although it may not be likely that both would go at the same time. There are three bulbs in the unit: brake/taillight, turn signal, and backup.
The units themselves come out pretty easy. Just remove the two phillip's head screws and pull the unit back to get it out. Then turn sockets 1/4 turn and out to check the bulbs. Bulbs pull straight out.
Hope this helps you.

Having the sa but haven't replaces the brake switch. The owner's manual for my 99 accord indicates the the fuse is located behind a panel that is viewable when you open the door on the driver's side. There is a panel that you remove (pull off) to expose the fuses. The brake light fuse is the third one from the top on the left. 7.5 A

These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!

take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,

Hello. Check relay RMI5 in REM unit located in left side rear of cargo area. As you look at it it's to the right of the central electrical connector 5th from bottom. Matt
