Rear window washer

[quack]

I have just realised that my rear window washer is no longer working. The rear wiper does work. When I turn on the rear window washer using the rear window washer switch the front window washers come on, as they do when I turn them on using the front window washer switch. I have disconnected the hose from the rear nozzle (by the top-mounted brake light) and no water comes out. I have swapped the hoses at the window washer motor and no difference. At the moment it seems that the hose leading to the rear is either blocked or pinched; this will be a nuisance to fix as I have a custom drawer unit which will need to be removed. So, in order to avoid this, first:

Is the standard behaviour for a PB Challenger that the front washers come on when the rear washer is turned on?

I know that there could be a problem with the column switch/ECU or ETACS, but I'd rather not face that prospect.

Thanks.

rear washers and rear wiper's only come on (not both front and rear unless you pull back on the lever) ...

do you hear the wiper washer motor when rotating the switch for rear wipers ... (check the fuse also) ...
