TD5 Front Wiper's

Guy's, can any of you assist.........

My front wipers used to, when switched to intermittent would work straight away, now it's some while before they get going.

When they do start there fine and work in all intermittent delay settings, so does the low and high speed standard settings.

Anybody had a similar experience or can offer some advice, my first though is perhaps a "Relay", but if it's not wired through a 13amp plug I'm a bit lost on that tricky stuff, :doh:

It's even trickyer than u can imagine, something which is supposed to be simple L.R. overcomplicated it... if u are a bit lost now u will be totally lost after u will read this(from the manual) :

Both the Body Control Unit (BCU) and the Intelligent Driver Module (IDM) control the wiper system. The BCU controls the time delay function of the wiper system and is located below and behind the passenger glovebox. Two relays are located in the passenger compartment fusebox. The relays control the delay operation of the front and rear wipers. The relays are an integral part of the fusebox and cannot be renewed separately. Power for the wiper system is supplied by the IDM, which is integral with the passenger fusebox and cannot be renewed as a component. A serial communication link allows communication between the IDM and the BCU.
The system has diagnostic capabilities through TestBook.

What u will understand is that if it's a component failure u have to replace the whole fusebox ofr BCU. U can check for water ingress at the BCU and IDM though cos it's quite common and it could disturb various systems

Well thank's for yor reply "sierrafery", and your right, what a complicated way of doing things :doh: double :doh::doh:

I'll check for signs of water ingress and go from there, I assume although complicated it's a matter of component/box change should it fail altogether and low IQ electrical twit's can do that?
