Horn fuse keep blowing

[deerefeed]

Does anyone have a wiring diagram for a 96 model with 3.4 engine? The horn fuse keeps blowing and I don't know what else is on that circuit to check. The horn works when the fuse is replaced but the fuse blows at some time afterwards.

I don't have a schematic that I can share, but the horn fuse powers the horn relay and the alarm for the seatbelts/ignition key/headlamps and turn signal. It's located in the same convenience center as the horn relay. Try removing the alarm and see if the fuse still blows. If so you may have a wire shorted or a bad horn.

Thanks, I did notice I left the lights on recently and the warning didn't chime. Where is the convenience center located with the horn relay and warning chime?

Under the right side of the dash. It has several relays in the top row, the alarm is on the bottom row, looks like a narrow box type thing. Will be the biggest part plugged into the center.

Thanks, come to think of it the horn hasn't been operating quite as it should. It has been rather intermittent when pressing the steering wheel pad. I thought it was just a bad connection in the steering wheel but maybe the horn is just all rusted away.

here is a wiring diagram of the horn for you.
