Wife just brought to my attention that the 95 Bonne SE'* wipers don't always work when switch to the high setting as they often just stop wherever they feel like it. Everything other setting works fine, as does the rest of the funtions of the MFS. I'm thinking multi-function switch is going bad. Sound like the culprit?

I had that problem with 94 *-10 and had to replace a circuit board. Its been a while and I dont remember all the details but I think it was located where the wiper moter is on the firewall. Pretty simple as I recall.

Don is likely on the right track. There is a circuit board (wiper motor pulse board) on the wiper motor that is probably your problem. If you can't find one you may have to buy a new motor.
