Why does the horn on a 1990 Chevy Astro work only while the vehicle is not running?
Sounds like the steering column shaft isn't grounded. When you push the horn pad, you are completing an electrical circuit which closes a relay & sends power to the horn & the horn sounds. If the steering shaft has no ground then the horn won't sound. The shaft has to have ground from the top where the horn slip ring is to body ground. Now for the horn working with the engine off. The only reason I can see for the horn working with the engine off is that the ignition key would be in the off position therefore the lock pin which is in behind the steering wheel locks the steering wheel is providing an alternate ground path which completes the circuit for horn operation. This ofcourse is not the correct circuit. Cheapest repair is a universal horn button installed. Button $5-$10.00 & install approx. $30.00.

If your batteries in the keyfob are OK then you need to synchronize your remote/s with the car using the following procedure:- 1, Ignition off 2, Key in ignition but leave ignition in off position 3, With key still in ignition press the lock button followed by the unlock button.
