Window control module

I have a series 1 XM SED driver's window inoperative. Motor stripped and works fine. Switch dodgy but working. Springs a little worn. What I need to know is anyone familiar with the little black box in the door attached to door cover with circuit board and two little relays? It just says bitron video and CA/PSA 12v on it no part number. Clicks when you try window switch but no output to motor. Will obviously reverse polarity too for up and down. Has circuitry so does more than just window may be part of alarm? Eight contacts in two blocks of four looks like Peugeot one I saw on Ebay same connectors just plug slightly different.
Any assistance appreciated and please don't tell me dealer only!!! I'm not a millionaire.

That is the circuit that makes the one-shot function work. The motor is fed with permanent 12v and the other side is shorted to Gnd via the switch.

I take it that the red and green wires which feed the motor reverse polarity so the window goes up again. How does the window module know when the window is fully up or down? Would low battery voltage effect it's function?
Any advice on a replacement switch would be great the contacts are all "springless". Any other Citroens or Peugeots use the switch as series 1 XMs very thin on the ground.
I'm basically new to Citroens spend most of my time in VW's Jaguar V12 and old Fiat 500 so need a lot of guidance. Have had the door locks to bits and sorted them out this was next job then need a glass screen for back seat divider.... Otherwise surprisingly good for a 20 year old car. Seats are superbly comfortable and aircon ice cold what more can you ask for except a driver's door window that works!

Hi Fiatson
Give us an idea where abouts you are.
Just a chance someone might be nearby with a few spare bits.

I'm up in Carlisle if there is anyone nearby with cars that are breaking. Need a N/S/F side light lens if anyone has one going. MOT not until August so not desperate. I had a look at spares on Ebay and was surprised at the cost of new old stock genuine Citroen; my XJS is cheaper to get parts for!
Any specialists parts companys that you guys can recommended?
