First and foremost, I’m not mechanically savvy but went ahead and replaced my turn signal switch on my 93 Jeep Cherokee.

Everything went smooth, put steering wheel back on and now the horn won’t work while the horn worked before. I’ve done this 3x now trying to figure out where I went wrong. I didn’t remove negative terminal when working on it and thinking somehow I didn’t align something right so when pressing button it’s not grounding? Not quite sure.

I’ve googled and searched here for over an hour but no luck.

Any help is appreciated!

 

Did you check for a blown fuse from working on it with the battery connected? I blew some fuses when I had my column apart without clearing the battery. I often skip the battery step on pre-airbag vehicles, but never on ones with a bag. They can kill if they go off too close to you.

 

hmmm. I checked all fuses before getting into the column but not after taking her apart. Luckily and unfortunately my model is pre airbags so I’ll definitely double check then tomorrow.

I put the concave plate outwards or towards me and the little pin in the spring/ switch? outwards which I believe it right but I’m not 100% sure on the plate. I swear I’ve done very configuration but might have to bring out the multimeter and see about the fuses tomorrow.

Fingers crossed.

 

When I tightened the tilt bolts on mine, I must have pinched or bumped the plastic tube the horn button rides in. As a result, it bound in the tube and didn't make contact so my horn would not work. Since it's spring loaded it was easy to tell once I figured it out. So make sure the little plunger goes in and out smoothly.

Next, I recall the disk spring was convex out, so the outer edge sits in the plastic ring. Clean any traces of rust off of it.

Since the horn only need to be grounded to sound off, you can take a jumper from that post and ground it before you reassembly to make sure it's not something else electrical.

 

She is apart now and I’m trying to ground it but not sure if I’m doing it right. I attached a picture of the two pieces I put a screw driver between and to my understanding... the right circle fires the horn when depressed and the main steering column should ground it? Am I right on this?

also attached a picture of some YouTube video spring pin vs the one that came out of mine. This guys pin seems different/ longer and should be same year/ model? A piece could’ve fallen out but I was pretty careful disassembling


Think this is how to ground it?

Anyone other thoughts? Is this how I’d go about grounding the horn from the wheel?

 

That last pic doesn't look good. The plunger should remain captured in the cancel ring.

Also looks like a piece of foil on the turn signal stalk. Not sure why that's there.

I'll pull mine off later today and get some good pics if you haven't solved it by then.

 

OK, here we go.

Your first pic looks like mine minus the foil. You are correct that the plunger is the horn. Simply ground it to the steering shaft and the horn should beep. Make sure your key is turned to ON (not start). The horn only gets power with the ign on. I can see yours is off since the wheel lock post is protruding.

Next, the spring loaded post in the cancel cam is in wrong. Here's a pic of the parts. Notice the small plastic sleeve over the plunger. That holds the spring and plunger in the cancel cam.

It should look like this.
