Hello everyone greatings from india. 

I own a mk2 skoda Fabia 1.4tdi which has rear wiper and washer without defogger. Ever since I got the car the washer never worked though I could hear the motor working, but the wiper did work. But lately since past few years I noticed the rear wiper stopped working time to time.  My main issue is that my wiper works when it like to. It has a mind of its own, morning it worked flawlessly but by night it's stops working. What could be the reason behind it? 

All suggestions welcomed 

Thank in advance.

If the washer isn't working, then check for a loose pipe. It's common (at least on the Mark 1 Fabia) for the pipe to pop off at the pump, or at the back of the engine bay if I recall correctly.

 

If you're referring to the wiper only, then I am unsure. I've had issues with the washer, but not the wiper itself.

It may sound like an odd question, but do the front washers work normally all the time?

The front works normally all the time. It's only the rear wiper which works when it likes to. Once it even started working without me switching it on. And I even tried turning on the front wipers and reversing, it worked few times and then it stopped working.

Ok, so the problem isn't the washer pump itself (if it were the front wash would be intermittent too). The most likely issue is a water leak as @AnnoyingPentium suggested upthread. From your other symptoms I'd start with the connection at the rear wiper and work forwards.
