My horn doesn't work. Following the diagnostic in the FSM, I found no voltage on 86 or 87. Next is say to check RED 1040 for a short. Where is RED 1040?

1040 is the wiring from there back to the fuse. You need to check fuse #3 (15amp) in the engine compartment fuse box. If the fuse is blown, then you could have a short somewhere but try replacing the fuse first to see if the short was temporary. The wiring diagram for the horn circuit is attached below. I would swap out the relay as well.

2000 buick park avenue. Horn does not work when you press on the steering wheel pad. Fuse is OK. Checked steering wheel contacts by putting an ohm meter on the fuse contacts. When press the horn button, the circuit closes. Swapped horn relay - did not fix problem. However, the panic button on the remote or double punching the door lock remote button does cause the horn to sound.
Please help. Thank you

there is a junction block under the right rear part of the seat. it could also be the module that is under the rear shelf in the trunk. that connects the remote and the steering wheel. However if you are getting power to the fuse then there is a wire that leads to the relay and they or it could possibly be disconnected. or not make good contact. unfortunately it's under the fuse block so the bestthing would be to test where #87 is on teh relay with a testlight as that should activate the relay. the relay will be marked on the bottom, it might take a magnifying glass to see it.

Hi hmac300:
Thank you for the reply. I will check it out this weekend. I am surprised to find out it is routed thru the trunk however we could have knocked something lose putting in golf clubs (has not snowed yet). I will let you know what I find out.
Thanks

Test your horn relay, located in the underhood bussed electrical center (on right front of engine compartment, forward of the strut tower)

I can't figure out why my horn won't work, I checked the fuses, they seem fine, I can't get the steering wheel cover off to check there. Also I have to change my serp. belt, Is it true I have to jack up the moter and remove the mounts to change the belt? If so that seems a little much.
Thanks Jeff

did you check horn relay? if relay and fuse is good then test the horn by supplying 12v direct power to it. if it sounds then either wiring issue or horn pad/switch is bad. if doesn't sound then horn needs replaced. for the belt..shouldn't have to, that is only required on the malibu and cutlass models..the park avenue should just have to loosen tension and remove belt..
