One horn is dead

Por_sha911 · Por_sha911's Garage

The high note (I'm fairly sure) is dead. Makes it sound like a toy car. I want to go stock. Is there any reason I can't just replace the one horn? (at 72.50 + shipping I'd rather not buy two if I don't have to)

I have the same problem and just took the horns out this weekend to look at them. They are individual horns bolted to the bracket with separate wiring. Removal and replacement takes about 15 minutes. The end of the horn, stamped on the bell, in english and german, indicates which horn is high and low.

Or, check the leads with a multitester...both horns unhooked, have someone "honk". Much easier on the ears. I wish I could buy a new spare set of original horns for my car. Food for thought if you plan on keeping your '87 very long.

If yo find that you need one, I have a couple of the short horns available.

Did you have to remove the bumper for access? Seems pretty tight in there with the brass oil cooler at one side & the bumper / valance at the other.

For an accordian bumper car...you can remove the small metal panel that forms the front edge of the fender...just behind the bellows...and then remove the bellows.

All set to go then.... best to take off that particular front wheel on the side you'll be working on.

Don't listen to Wil he just likes taking his car apart. It's winter, he's bored.

Jack up the passenger's side of the car high enough to get under the car. Put on jack stands. Look up under wheel well in front of the oil cooler. The bracket for the horns has two bolts. Remove bolts. Horns fall in your face. Pull off wires. As the Haynes manual says "reinstallation is the reverse of removal."

If they work just tell me how much you want for them.

Kurt V,

I just recently realized that I have accumulated too many spares for my car just sitting in my shed. Most of these were purchased for my personal use. So I'm selling them for the price I paid at the swap meet (Hershey) no mark-up.

Paid $45 for the OEM horns and will send you pictures if you're interested.

Kurt is right... ( about there being another/yet simpler way...not the point that I particularly like taking my car apart for no reason ...LOL !)

Especially with long ratchet extensions..access is OK from below. The method I suggested offers some options to remove one ( say..outermost) horn and its electrical connections, etc. w/o having to take the support "bridge" of the two horns out..from below).

But basically Kurt is correct.... your choice....

Joe,

My suggestion is to clean the electrical connections, first! A stainless steel brush and 9% pickling vinegar, followed by distilled water rinse and compressed air drying is my standard procedure. After operation is restored, I recommend a liberal coating of Dow Corning 4, 111, or 112 silicone grease on the connection.

Horns are notorious for being 'picky' about corrosion on the terminals ... and they don't live in the cleanest environment around!

Joe,
Check for 12 volts at each horn before you buy a new horn. Could be a broken wire.
If in doubt remove the horns and test with your battery and a couple wires.
May be polarity sensitive, check for markings.

Warren: Thanks for the good advice. I have already checked the contacts and they look really clean (the car is mostly a garage queen so its fairly clean under there). I pulled one set of wires and got no sound at all (but i don't remember which one it was-duh). I planned to get a multi-tester under there to see for sure.

Sergio: I may drop you a PM if I verify that its the high note.

Kurt: um, you're a little fast on the draw there buddy. Tony was responding to the thread I started but hey, if you need them, go for it. Its not worth fighting over. I just think it was poor form on your part to jump in like that. Some people would be greatly upset (sorta like hijacking a WTB thread). Thanks for the info on the stamping on the horns.

I just turn the car max to the other direct and lay down on the ground. They are just hold on to a bracket with a bolt.
They are 2 separate high and low horns.
I hate the sound of it. No idea why they are so expensive but that is good. I plan to get some modern type horns and send them to ebay :lol:

Not sure I was fast on the draw. My post was TWO HOURS after boyt911sc made his offer. On the other hand it is just a pair of horns and I was thinking of going aftermarket anyway. I defer to you. The horns are all yours.

I was able to disassemble the horns and clean the contacts inside of the unit to recover its operation. It is worth a try unless it is real real hard to get in and out.

With my 74' and Brass cooler, I was able to get them out with a little effort. I think I disconnected the lower mount for the cooler and swung it a little bit out of the way.
