The horn will honk & the speedo will bounce in time with the car moving.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The buzzing you are describing can be caused by a poorly grounded relay. I see you say your mechanic replaced a relay . Can you find out what relay was replaced so I can look at the wiring diagrams and see if I can help you determine why its buzzing. Post back when you can and we can work from there.

It's not the bushing that's the problem, it's the horn honking & the speedo bouncing. I was hoping you could diagnose the problem based on those REALLY WEIRD issues.
Expert:  Ron replied 10 months ago.
I suspect these problem are related to the relay that buzzing. Do you know which relay it is that buzzing?
Customer: replied 10 months ago.
He called it a control module. I think there must be a short somewhere.

I would agree but unfortunately Im afraid this is something that is going to require some hands on testing. I will open the post back up for you and perhaps someone else has ran across this type of issue and can offer something different. If they can help you they will respond.
