The front wiper does not work on INT (intermittent mode)and LO (low mode). Everything else works (rear, high, mist, washer). I got a new switch and installed, but the condition did not change. Now I know it is not the switch that is causing trouble.

Someone said it could be it could be “relay.” But I found out that I found out there is no relay for the front wiper.

Plese help
