I have a 1998 C2500 Chevy truck I replaced the horn fuse and all I get is a clicking sound from the horn relay. Should I replace it also? What else could be wrong?

None at this time.

There are some connectors behind your steering wheel that may be messed up. My 1999 chevy s10 had a dysfunctional horn I had to remove the airbag from the steering wheel to access the wiring harness to the horn and i had a broken wire that caused the horn not to work I replaced that and problem solved. Also Your actual horn is usually located in your front bumper and that may be damaged if it is replacing it will fix the problem. Hope this helps good luck

SOURCE: 1998 Lasabre horn sounding

I solved this issue on my 95 Riviera, I'll bet all GM vehicles with this type horn switch will eventually have the same problem. It's what the other guy said, too much tension on the vinyl cover. I looked up the patent info and found they changed the design of the horn switch to use a membrane between the air bag and the vinyl cover. On mine the switch became super sensitive first, then it eventually stayed closed (horn on all the time). If you are blowing the 20 amp fuse remove both horns and use a meter to read ohms (should be 1.2 ohms if .4 it is shorted). The horn switch is not a "serviceable part" but if you have the same issue as me you can fix it. First make sure it's the horn switch causing the problem. Remove the airbag from the steering wheel, pay attention to the warnings and do what GM says to disconnect the SIR system (small yellow connector under steering column.) Put electrical tape over the SIR connector off the module so you don't make a mistake probing it with a meter. You can easily check the horn switch now with your meter (it's the small red/blk connector harness terminating to a two conductor ribbon type cable. See if its shorted. Remove any torx bits and any switches. You need to drill out the eight outer rivets that clamp the vinyl cover (do not remove the inner rivet for the module. just drill enough to pop the head off, you can use a sharp small chisel when you are close. Use duct tape to keep metal shavings out of the bag area. A dremel can help in this job. Use needle nose pliers or I used large gas pliers with a nut as a spacer under the flared remainder of the rivet, and pressed out the rest. You might have to dress up the exposed cut rivet so it fits thru the hole (i used dremel). Just get the rivets out. Place the module in a safe place. You need to remove the vinyl cover and grind down the high spots of the molded grid on the inside (I used dremel tool). Try to make it as even as possible and don't go crazy. Put it back together without the module just the hard plastic backing/membrane switch portion and use your meter on the horn harness to make sure enough material has been removed. Basically you are taking off a tiny amount of 1/32" or even less all over. You will have to press harder now to activate the horn so don't remove too much material. Reassemble using 1/8" dia x 1/2" long steel rivets when you are sure your done. This is not a difficult job, and it beats buying a new $700 or more airbag to fix a lousy horn. If you are intimidated by the module staring at your face the whole time you might want to drink a beer first to relax before starting. If that thing goes off it will shoot that steel plate in your head so be careful and do not probe that yellow connector with your volt meter. Otherwise you should be safe!

SOURCE: 2001 Silverado: horn or horns do not work Hit switch and can hear ...

only one horn sounds when you hit the button. the other horn is for the alarm and door locks etc. im not sure which is which, but have someone push the horn button while checking for power and ground at the harness connector. if power and ground are there, replace the horn. for your own sanity, buy an original equipment horn that just plugs right in, a universal aftermarket requires you to frankenstein your wiring. good luck!

Troubleshooting no spark

Were both engines the same year? Some model 2.5's had different crank angle sensor tabs on the timing gears. Usually, if that's the problem, you will have spark on 2 cylinders and none on the other 2 and none will be fireing at the right time.

None of them??? If the driver's works but the rest don't, check to make sure you didn't hit the lockout switch on the driver's door that turns off the other doors for travelling with kids. This happens ALL the time with Honda's. If none work, start with the basics. Check ALL fuses and relays, etc.

The controls for the heater & a/c are not working. I lost one blower level at a time, and now none. any suggestions

none of the controls are working? or just the fan control? if it is just the fan control, your problem is the blower motor resistor. it is located on the airbox, close to the fan motor.
