I've checked the fuses and everything is good. Relays good also. Anything i'm overlooking btw it'* on the 94 SSEi.

I don't know about the horn but there'* a chance (slight) that there might be an inline fuse that'* going into the radio that you overlooked. This would be more of a reality with an aftermarket unit.

do you think that these issues are possibly related? why?

I got the radio issue figured out. Still no horn though. Fuse in the main fuse box is ok. I"m gonna check the other fuse panel when I get a chance.

does the horn relay click?

No clicking from relaly.

The horn button is most likely toast.
It'* inside the airbag assembly.

I'm happy with just an added an external microswitch,
on the console shifter.
I ran the wires to the relay'* coil connection (black wire)
and the other to ground.

The horn relay is activated by grounding it'* coil energizing the electromagnet, and therefore closing the main contacts. releasing the ground connection reverses the operation.

What did the problem with the radio turn out to be?

this post is older than the other one you dug up.
I understand you are trying to get some help but please do not dig up really old post.

I moved your thread to this section. Please have patience waiting for replies.
