Q: Horn Problems on 1996 Mercury Grand Marquis

96 Grand Marquis Horn Problem -- One horn has been working, the other not. I cleaned and tightened all electrical connectors and checked the horn relay for operation. All Ok, but still had only one horn. a couple of hours later the second horn stopped working. I swapped in another good relay with no luck. Does anyone have an idea or suggestion about this?

Sounds like you need to replace...the horn assembly. If you've checked the ground and the power and both are good -- the horns themselves are likely in question.
