Apologies, I put the in wrong sub-forum. Dear Prius Chat, First post, long time auto monkey but first time with a problem I can't solve or cannot find anyone else who has the same or had the same problem. Purchased the car used from car lot with 83K on it and have had it about three weeks, I really and I mean REALLY enjoy having driver window cracked with RR window cracked for cross air flow. In the meantime, I'm learning to improve my MPG. Driving a Geo Metro prior to this really helped. 2010 Pious III Issue: Right rear power window not controlled by driver switch Symptoms: No control from driver switch (all other windows operate from drivers switch) Right rear window controls fine from right rear switch At any point with car on or off, right rear window switch is active and will roll window up or down. The only way to disable this is to pull the fuse for the RR Window. What I have tried: Replaced master switch - did window reset procedure (same problem) Swapped rear switches - same problem on RR Window. Issue did not change windows. I pulled the RR door card to see if there was something funny with the wiring: nope, everything was normal. Though it appears that somebody else has attempted to see what's going on because the vapor liner has been removed before. At this point I'm absolutely up for suggestions.
