Hi All,
I'm new here but have been following this thread with considerable interest because my 1999 Rodeo has the same intermittent wiper problems. The front and rear work pretty much how and when they please. To fix this I ordered three of the NEC EQ1-31000S relays from Mouser and installed them in my board. Now the fronts work great, but the rear doesn't work at all. When I push the button, the relay clicks but the wiper doesn't move. I even swapped the RY3 and RY4 to see if that had any affect. Nothing. Both wiring connectors are solidly connected to the board and I even tried wiggling the connectors. Nothing. Does anyone have any ideas? This thing is driving me crazy.
