when they installed the rb25, it looks like the wiring conversion was a little bit sub par.
Im pretty sure its still running some of the rb20det loom. The plug for the wiper motor does have a few wires taped over so maybe it was connected the wrong one.
There is no power getting to the motor in the first 2 speeds, but there is at the 3rd.
Also, the wipers dont reset when i turn the switch off, so im thinking power is only going to the high speed wire?
