Loose Horn Switch

imported post

I had some sticky switches, so I tried sprayingWD40 in all the openings and it worked for some switches, but it made the horn switch worse. I decided to disassemble the switch assembly and do a good cleaning. During re-assembly, I found the horn switch would rotate around its mounting screw when the button was pressed. It wouldn't actuate the switch and it wouldn't swing back out. Since it wouldn't actuate, no horn.

I tightened the screw and all seemed well. After completing the re-assembly and testing the switches again, the horn switch began rotating around the screw again. Tightening the screw should hold it, but it isnt. Is there supposed to be a tab somewhere that stops the switch from rotating? I didn't see a tab.

I wiped off the WD40 from all the parts before re-assembly, but there is still a film which is probably contributing to the problem. What would clean the WD40 off the plastic completely?

I've thought about wedging something between the back of the horn switch and the housing for the turn signal switch so that it can't rotate when pushed. I don't think it would be in the way of anything. Is therea better cure?

If you decide to disassemble your switch assembly, carefully note where everyting goes and have patience. It was much easier than I had thought it would be, but I can see how it could be frustrating getting the pieces back where they are supposed to go. A lot of wiggling of the housing was needed to bet things in the right positions.
