Hello, Your horn should have 12 volts at the wire to it,if no voltage then its in the horn circuit from fuse panel. If it has 12v then proceed to your horn pad, your car has an air bag and it is attached to the steering wheel with two torqs 30 bolts that are housed inside a small hole in the back of the steering wheel. Place your steering wheel at 3:00 and you will see the hole in front of speedo. Loosen the bolts and remove the air bag to the point where you can see the black wire attached to the horn ring, check for 12 volts at wire. If there is no voltage you will need to disconnect battery and put a baggy over the negative battery terminal wire end. (If there is voltage the problem is in the ground at the horn ring or the ground on the steering column under the covers.) Now you can remove the connector from air bag module and then remove steering wheel, rock it side to side gently and it will pull off. Be careful of the squib connector so that it doesn't get caught on the wheel when removing. next, clock spring alignment is critical, when the wheel comes off the spring will want to turn in one direction, prevent from turning with a tie wrap. Now you can check the wire to horn with a volt/ohm meter with test lead to bat. and wire with ignition on position 1. Also check the two ground wire connections under the cover and back by the edge of dash pad. Make sure screws are tight.

hello fao- take the bottom half of the steering column cover off and look at the ground wire which is held on by a screw which comes loose and sometimes falls off.oldduke
