As it has been a very dry year I haven't really used the rear wipers much. This morning when reversing down my drive I turned them on to see where I was going and they didn't work. As soon as I selected N they worked fine.
Following some investigation I worked out that the fiendish Chinese programmers have built in some weird anomalies, or perhaps didn't think through all the possible options.
This is what happens (I think!):
Front wiper selected to off and rear wiper to on: Rear wiper works on intermittent wipe in any drive mode (R/N/D).
Front wiper selected to auto and rear wiper selected off: When mode selected to R, rear wiper works continuously but only if the auto front wiper is wiping continuously, if front wiper is working intermittently or stopped then rear wiper does not come on when R is selected. This I can live with
Front wiper selected to auto and rear wiper selected on: If the front wiper is wiping intermittently or not wiping and rear wiper is set to on, the rear wiper works intermittently in N/D mode (as usual) but as soon as R is selected the rear wiper stops which is very annoying.
Front wiper manually selected to slow or fast speed : Rear wiper works continuously as soon as R mode is selected even if turned off. If rear wiper is turned on then it works intermittently when in N or D and continuously in R.
As I usually have the wipers in auto I have to select off or slow speed if I want to wipe when in R mode. A pain.
Or is it just my car?
