the horn on my 89 suburban is not working.
I have checked the fuse, it was ok. should I check the relay next? or could the horns themselves be bad? need to fix this, otherwise, I have to use My finger

If you use a second guy you can use a test light at horn and get them to press horn switch. Then work your way back.

If you suspect its the horn use a hot wire from the battery (preferably with an inline fuse) and give it a blast.
My moneys on either the relay, or the steering wheel switch.
For the steering wheel switch use either a short tester or a multi meter, after you get the steering wheel apart test it while pushing the horn contacts on.
For the relay make sure you have power from the battery (this should be a full time hot) find the switching wire and use a jumper from the hot, then test the horn power wire for voltage.
This could also be a good time to install an inexspensive air horn from Auto Zone. It'll probably cost near what you'll spend in NOS repair parts.

My high note went out
and I just replaced it last week. On mine it was behind the battery--a little aggravating to get to, but I have seen worse! I had a dickens of a time getting the correct one. The Chevy dealer wanted $63.00 for one horn! I wound up getting it from NAPA for $28.00. It is OEM and the same brand as the factory--"FIAMM" brand. I tested mine to make sure it was the horn and not the relay with a test light by clicking the remote to make the horn chirp.
I had to do something --we had 2 instances on vaction where we needed the horn to work and I could not to my finger fast enough
