Saturn Horn replacement

**slugbug** · 07-17-2009, 04:54 AM

The horn on my '99 Saturn SC1 failed so I called a few auto parts stores only to find out that its a dealer only item. Saturn used a 3 wire horn with an integrated relay and a replacement costs a whopping $85.00

The problem with having the relay attached to the horn is over time water gets into it and it fails. Most vehicles have the horn relay in the fuse box where it belongs, and use a 2 wire horn.

My nephew is scrapping his '86 BMW so I was thinking of taking the horn and relay and jury rigging it to work on my car. Should be easy enough to do, don't you think?

Here's a wiring diagram I found:

should be easy enough. the relay i beleive to be grounded as well.30/86 one of them will be a ground

is that a postive ground? bc the way i wired relays was you have 1 switching voltage (the item that excites the relay, 1 input man power line, 1 ground, 1 out going power, this way the relay acts as a cercuit breaker and pulls from the main power and not through the switching power.

here is a link for a used one on e-bay. It is for an 01. I don't know if it will work or not.

No good for me, the seller ships to the US only.

Find a Junk Yard and match up your relay , alot of the chevys use the same relay...

But you probaly can pick one up in a junk yard for next to nothing..

As I've already mentioned, Saturn has the relay built into the horn and the local scrap yards don't have any. I'm gonna pick up a universal horn and relay. Just need to figure out where to put the relay.

I know that this has been a long time ago thread, but reading the whole replacement horn thing here seems to be quite interesting. A good saturn repair is a good key here, and understanding it very carefully would have been the essential tool here.

Check if the horn is still repairable. If yes, you can find in the internet good Saturn repair questions that would be your guide in this. There are some auto repair shops that wouldn't know how to repair some of the parts of that car because Saturn are rare.
