I've been dealing with a non-operating horn since I purchased my '95 pickup. I've got some time today so I finally decided to look into it.

The hazard-horn fuse under the hood is good, but I don't hear a clicking in the relay in junction block 1 behind the driver's side kick panel. I took the panel trim off and located the relay, however, it's near impossible to remove. Is there some sort of push-tab that needs to be depressed before it pulls off? I got the white plastic housing that the relay sits in off (it had a push tab that connected it to the fuse box), however, I'm still having issues getting the relay off of the housing. I stopped trying to pull it off because the entire fuse box started to bend and I didn't want to break anything. Wires on the white plastic housing are too short to pull it out any further.

Any suggestions?

 

From what I can tell the relay just pulls straight out. Here a video I found for a '93 but your '95 should be exactly the same.
If it's the original relay it could be a bit stuck in there, so a few short blasts of WD-40 to lube up the plastic sure wouldn't hurt anything. That plus a bit of wiggling & patience should get it out.. Just take your time with it.

 

Hey 13Swords, yeah this is the video I saw that helped me locate the relay (I was stumped about where it was initially, haha). Mine definitely feels stuck, no way it's coming out that easy. I'll try the WD40 method and report back.
