I had the same problem in my 1990 244DL. You really had to slam hard on the wheel to get any sound. Sometime that wasn't even hard enough. Here's what I did:
Disconnect the battery. Wait at least 5 minutes. This is to prevent residual juice from deploying the airbag. Remove the plastic crap around the column. This allows you to get access to the two screws holding in the airbag. Once you remove the two screws from behind the wheel (they're torx bits on my car) the airbag should just lift off. Unplug the bag. You can now see the element that enables the horn to work.
There are two strips of metal, well four actually, two strips per side. They are about 3 or 4 inches long and are separated from their contacting point by springs. When you press down on the bag, you're pressing these metal strips together. The problem lies withing the points that actually make contact with each other. They're tiny. I cleaned mine up real well, but they seem to get flattened over time. Once you remove the airbag you'll easily see what's what. You could but a brace between the metal strips and then tap slightly on the contacting point to make it stick out a little farther, therby decreasing the travel distance necessary for it to make contact and complete the circuit. By far the hardest part of the job is getting a screwdriver into those tight holes behind the wheel that hold the airbag in place. Good luck.
