Good news!

You don't have to change out the wiper motor. I called a local Honda dealer, and the part number is the same for DX/CX/VX/LX/HX/EX/Si. What makes them intermittent is just the switch and maybe a relay... I'm still checking on the relay part to see if it's integrated. The dealer won't help me any further because what I'm doing is a hack and not a stock setup. So what! The car's 12 years old!
