Hi, long time member, rare poster. 2004 Odyssey EXL w/ 230,000K (and the original, babied tranny). I searched this topic, and have tried several suggestions, to no avail.
Symptoms and attempts to fix Rear Wiper:
1. Turning on the rear wiper switch does nothing, no movement, no sound. No other symptoms in car, no SRS light issue, nothing.
2. The fuse is good #11 under drivers side dash (checked all other fuses as well just in case--all good)
2. I replaced the rear wiper motor with a guaranteed used Honda part from ebay for $50. Didn't fix the problem.
3. I replaced the rear wiper relay (Mitsuba RC-5102) located under the left rear speaker housing with a new relay from O'Reilly - didn't resolve the problem.
4, I get 12v constant power from one of the four leads going into the motor harness. No other power from the other leads that I can read.
I'd appreciate any help or diagnostic ideas you guys have to help me run this problem down. The only thing I can think of in the circuit is the switch in the wiper stalk on the column--but that seems like a long shot, and a serious pain to fix.
