Berlingo 2005 heater blower electronic diagram

[numanoo]

Hi ,

I have a 2005 Berlingo diesel van. The problem was that the fan was continually running fast and wouldnt stop.
I removed the blower and checked out the power transistors. One of them was faulty. I replaced the pair with equivalent new transistors. On re- assembling, the blower will not start up at all now. I was interested to see if I can find an electronic schematic of the ciruit board which contains the two transistors. I am unsure as to the signal values I should be seeing at the 4 pin power/control plug on the board??? It looks like the relay on the board is not energising and wanted to diagnose further to see if I cant find out if problem on circuit board or with the control signals going to it??? Any help much appreciated.

Many thanks
