Try to find the horn and use a test light to try to ground out one or the other contacts. The horn should be energized at all times, as long as the battery is charged.
The horn should sound if you ground out one or the other terminal with a test light. If not, then the horn is bad.
Also, one can check the button at the steering wheel. If one uses a test light to ground out the switch there, the horn should sound.
See fig. 3 for wire for horn in steering wheel:
REMOVAL & INSTALLATION
Without Air Bag
See Figures 1, 2, 3, 4, 5, 6, 7 and 8
Disconnect the battery ground cable before removing the steering wheel. When installing a steering wheel, always make sure that the turn signal lever is in the neutral position.
- Disconnect the negative battery cable.
- If your vehicle is equipped with controls for the radio on the steering wheel proceed as follows:
Fig. Fig. 1: Pry out the control button assembly with a thin-bladed tool along the top of the edge, being careful not to damage the control assembly
- Pry out the control button assembly with a thin bladed tool along the top of the edge of the assembly.
- Disconnect the steering wheel control.
- On vehicles without the radio controls on the steering pad, take a thin-bladed tool and pry the pad off the steering wheel. On wheels with a center cap, pull off the cap.
Fig. Fig. 2: Common steering wheel pad types
- After lifting the trim off, pry the horn wires from the back of the pad. On some models gently push down on the horn lead and turn left, the wire and spring will then come out of the canceling cam tower.
Fig. Fig. 3: Carefully pry the lead wire for the horn off of the horn pad
- Remove the retainer ring with a pair of ring expanders, then remove the steering wheel nut.
its still the factory stereo...and no the air bag light is not on...Im trying to control the radio from the steering wheel, but the buttons for that is not working...i.e. mode, & volume control..
yeah reason i was asking about the air bag is because there is a ribbon wire in the column that lets those buttons be connected but still let the steering wheel turn i have seen those break but they are very expensive and usually disables the air bag in the steering wheel as well since the air bag is hooked to that wire as well. it could be a number of things other than that as well though. could be a faulty head unit or plugs getting corroded or coming loose anywhere in between. how long have you had the car some of the factory head units cannot be controlled with the buttons on the wheel wondering if they have ever worked since you have had the car maybe someone got a new radio or steering wheel out of the junk yard before you acquired the car?
is it still the factory stereo or did someone change the head unit out? also is your air bag light on in the dash?
