Where is the horn relay located on a 1994 GMC Sierra 1500 pickup? My horn won't work and the CTSY fuse should be good since the radio clock and dome light are working. I'd like to test the relay but can't find it under the hood.

Definitely a ground. Clean everything with light sandpaper. Follow any/all wires and see where it grounds, clean there too. If all else fails, run a new ground wire from the frame to the exact spot you got the bulbs to work (a workaround that usually remains permanent on my cars!).

engine compartment relay box. There is also a horn relay there.

Please see my tip at http://www.fixya.com/cars/r6022358-relay_check to check the relay and socket. These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

SOURCE: 2005 sierra horns stopped working.

The click you hear is the horn relay -- this likely has either dirty / corroded connections or burned contacts inside the relay. If cleaning all relevant connections doesn't solve the problem, replace the relay. You can find the realy by having someone push the horn button while you track down the click.

Are you sure the fuses are good? Have you try to replace the fuses?

Where do i find the horn fuse box on a gmc sierra a 2002


There isn't a fuse. Just a relay. Either the relay is dead ( not likely) the horn is dead ( most likely cause) Or the steering electrics is bad. ( most likely on this is the plastic piece inside the steering wheel has broke)

2001 gmc sierra 1500 injector fuses and relays


Do you hear the fuel pump running on the prime cycle (when you turn on the key) (runs for 3 seconds) or when you have oil pressure?Have someone listen back by the tank for the wrrrrr.If you do have to change the fuel pump,make your life easy and just tilt up (lift) the pickup box from the drivers side to access the fuel pump.Takes 20 minutes to change it that way.

Horn on 2002 Gmc Sierra 1500 stopped working. Horn stated boleing fuses a couple of years ago and was just changing fuses to fix problem short term. Last time horn stopped working I changed fuse and it did...


Sounds like the horn itself is shorted out. You didn't mention if the blown fuses were a result of using the horn. A horn in construction is an electromagnet acting on a diaphram; if the electromagnet develops a short, it causes an overcurrent condition and will blow the fuse.
