90 Horn Problem

[E B.]

Horn system on my 90 coupe stopped working from the buttons. IS THIS A COMMON PROBLEM AS jAMES White suggested in his post on the 1990 ZR-1 time capsule? I've already had the other usual problems with the car. NOTE, horns work with 12 vdc applied. thanks Ed Bauscher

Re: 90 Horn Problem

Ed cars with Air bags on the steering wheel do have clock spring problems sometimes. I don't have a wiring Dia.handy, generally at the base of the column the turn signal switch harness is located there, You'll need A Volt/ohm meter. find the correct colored wire and use the ohm meter to check for flow when hitting the horn button. sometimes if you take a 12volt test lamp and just touch each wire you'll come to the wire that operates the horn relay. and when you touch that wire the test lamp will act as a ground and the horn will beep.

Thanks Edward for the heads-up on the clock spring, I've had similar issues with other cars. 90 only has 44k miles but its still 23 years old. sincerely, Ed Bauscher
