i have been looking around the forum for a write up on how to fix the wipers on the fc and cannot seem to find anything.

i have replaced the switch, harness and wiper motor on my car and still it only works on 1 speed. the only thing i havnt replaced is the harness that goes to the wiper motor. but if anyone can send me the link to the write-up that would be great.

thank you

 

The problem is in the switch, just search for fixing the switch

 

I had the same deal on my 87 t2 , i checked everything and it endid up being a bad connection in the switch, if the wipers worked on one speed that mean's the wiring is all good, the fault is in the connectors when you twist the switch, pull the switch and see if its just corrosion if not replace, I have a parts car so it comes in handy for little things like this, good luckand always double check everthing before you replace parts it can ave yo a bunch of money,
