My 96 SL2 horn started blaring while sitting in the garage in early April. Saturn had a recall for this many years back in the US, but my dealer in Canada know nothing about it.
So I bought a new horn thinking I'd at least cheat them out of installing it. Last night I decided it was time to do the deed, and like the toilet salesman, I'm flushed with success.
First job was to remove the headlight assembly so I could reach the horn. I had read about the procedure on some web site so I knew what to look for, sort of. I had to do some detective work to find the right bolts. There are two of them, one high, one low.
Once I found the two 10 mm fasteners I removed them and the headlamp assembly lifted out of the way, and hung by its wires. I touched the plug to the old horn and it was still stuck.
Now I could see the horizontal 10 mm fastener holding the horn in place. It wasn't difficult to remove, except I could only take small turns because of the narrow opening. I took off the old horn was and fastened the new one in, complete with mounting bracket. I put the power connector on and no blare, so I was on the right track. Then I hit the horn button and it worked! Last job was to put the headlamp assembly back.
So it's quite easy, a 10 mm box end, a small extension, a ratchet with a 10 mm socket and you're in business.
I haven't blown a horn in anger for three months, so don't get in my way!
