This just began occuring- horn works in the a.m., works during the drive to work - 20 min. on pretty straight road. turn right into the factory and no horns. at all. Very sporadic. I pulled the horn button covers - no hot spots, or non-contacting switch parts to be seen. The FAQ on this is rather spare. Do the horns have a relay? All other electrical connections in the steering wheel work fine. Thanks to the FAQ for tips on getting the drivers power seat to function on all positions. I found a slight burn mark on one of the stop button solder posts. I bridged the two posts, all works great. finally. No horn is no fun. thanks.
