'93 245.

Originally, when I pressed the steering wheel, the horn was pitiful, so I got suggestions from brickboard. I installed a relay in the front grill area, such that battery power would be directly routed (via the relay) to the horn when the steering wheel was pushed. This worked okay until the relay got stuck in the on position and the horn sounded continuously; luckily, the car was in the driveway and not on the road! It appeared that the relay had gotten wet, when the car went through the car wash, and shorted out. So, I bought another relay, installed it, and wrapped it tightly with black electrical tape; however, it also quit working, probably due to moisture intrusion.

I'm willing to remove the relay modification, and go back to original, or whatever I need to do to get the darn horn to work reliably. I don't want to get into a situation where the horn starts blowing when I'm driving the car. Any suggestions or links that I can view??

Thanks,
Cabbie

Install the relay inside the car. Or remove the steering wheel and fix the contacts.

Never removed the steering wheel before. Sounds labor intensive. Probably the right thing to do though. Putting the relay inside the cabin seems like a good solution too. Apparently, this is a common issue with the steering wheel contacts not grounding well. Or at least I remember something like that. Sounds like a weird design.

Disconnect battery. Wait a few minutes. Remoev torx screws taht secure airabg. Move airbag out of way. Find contact springs. Clean contacts, pull springs apart slightly to make them a tad longer. Replace airbag. Connect battery. try horn.

I also had to clean the contacts in the horn button/airbag. But...also needed to take off the stearing wheel to get the contacts on the back side of the clock spring; there's a circular contact that needs to get cleaned and polished. Do you have a bently? If not I can reply back with the procedure later when I can get my hands on it. It's not that hard to do.

I do have a Bentley....but must admit....going into the steering wheel seems like a daunting task.
