Hey I have a 86 n/a rx7. The wipers only work on the constant setting, but not the fast speed or intermittant. There is only power on the blue wire to the wiper motor. I replaced the switch and nothing changed. Any suggestions would be welcome. Thanks

 

did you replace it with a "100%" working unit ?

cuz it sounds like the replacement is also broken.

 

The problem is a dead relay inside the unit. Icemark used to rebuild them, but his page is now down that shows how to rebuild it and contacting him is a bit difficult.

The only sure way is to go factory new or replace it with a 100% known working unit.

 

Thanks guys, I found one that I knew was good and swaped it. Solved the problem.

Thanks
