Has anyone else had a problem with the rear wash wipe switch also activating the front wipers?
On a year 2001 model, recently acquired second hand (single owner, serviced by Lexus), whenever I activate the rear wash wipe, the front wipers go on. This has been occurring since I got the car 6 weeks ago. I was going to have it checked at the next service in the Summer. I think it has been going on for some time - possibly since new - but I can't confirm this. The reason I suspect this is the case is that the front screen is etched with the wiper arcs from all these dry wipes!
Yesterday, driving south, into low sunshine on roads that had been salted, I activated the rear wash wipe. The front wipers came on. There was just sufficient moisture on the screen to turn the whole thing into that white mess that you get in winter. This caught the sun, I lost sight of the road and nearly ended up in a ditch. The car is now booked in with the local lexus people to get it sorted out.
It doesn't strike me that this could happen as an acquired fault. It really sounds like a primary error in the wiring when the vehicle was built.
Does anyone have any comments?
