    My horn has stopped working. I hear the relay clicking when I push the button, so I think the problem may be the horn itself.

    Can anyone give me instructions for accessing and removing the horn for testing? I have an '81 308 GTSi.

    b4 you even take the horn out,there are three screw's on top,take those out and pry off the lid,squirt about 3-4 drops of 3 in 1 oil,put back the lid and see if that works for you,alot of times these horns need to be lubricated on a regular bases

    The unit is located in the right front near the headlight motor. Open the front boot and look between the right headlight and the spare tire well. You will see the the rounf top of the compressor with the three screws that were mentioned. No need to take anything apart.

    I found the compressor in my car, but the location is a bit different than what is in the photo.

    I was wondering about the plastic tab on the top of the compressor that reads "oil". Should I be adding oil there instead of taking the cover off, or is this for adding oil as regular maintenance? And if so what kind of oil am I supposed to use? Thanks.

    Both -- some compressors have the oiling port (so add the oil there) and some don't (so you have to disassemble the cover to add the oil).

    A light machine oil is ideal (e.g., sewing machine oil, 3-in-1 oil), but almost any oil is better than nothing. (Assuming the +12V is reaching the electric motor) You might still need to disassemble and clean things up (if you are presently "frozen"), but try adding a few drops -- if it doesn't work immediately, it might after allowing a few minutes for the oil to wick around, but if still dead = disassemble.

    It really does help keep the compressor in better shape to "toot" the horn once in a while.

    Thanks everyone for your help.

    It turned out the compressor wasn't working because the fuse was bad. I replaced the fuse and the compressor worked but the horn did not sound (I oiled the compressor anyway). I removed the horn and it seems to have been clogged up with rust and mud. I tried to clean it out but it still didn't work.

    So, I installed a cheap plastic air horn I had lying around next to the compressor and connected it with a new air hose, and it is working great for now.

    I will see if I can repair the old horn. If it does not work I will decide if I want to keep my cheap plastic horn or replace the original, which T. Rutlands sells for about $110 delivered.

    In the meantime, thanks for all the advice. It is good to have a working horn again.

    This picture isn't helping me much. Does someone want to give me a clue to what I am looking at?

    First picture was taken fore of the front passenger tire in the area below the headlight. The area is almost too clean to be recognizable.

    In my car the compressor is on the other side of the bulkhead shown and the plastic tooters are in center ahead of the radiator and is accessible from above near the bonnet hinge.
