Citroen Picasso Drivers Side Window Regulator
The wire pully system on the drivers window regulator had broken down so I set about changing it. Any solutions as to fix front electric window on a Citroen Picasso? It has gone down but wont go back up!!! It could be that the widow has dropped from the regulator (mechanism which holds the window) causing it to jam, it also could be that that a conection from the motor has come loose. The front passenger side.

Fault Presentation
Here's what to do if the driver's side electric window on the Citroen Berlingo (Mark 1) fails to operate correctly, operates intermittently, or becomes stuck in one position. The Peugeot Partner can have the same fault.
What if it's only the driver's door?
If only the driver's door electric window fails to operate or operates intermittently, the most likely cause is a fault in the Electric Window Module (ECM). The fault is most likely a bad joint in the printed circuit board (PCB) of the ECM. The repair described here addresses only that issue.

Before You Begin
Before starting your repair, make sure you have identified the problem.
- Make sure the glass itself is not jammed by the rubber seals and runners. If it is, using spray furniture polish can unstick the glass.
- Make sure no physical damage to the wiring boot to the door is evident.
- If both front electric windows fail to operate, then the fault is probably not in the ECM but elsewhere in the common supply to both windows, such as the fuses, relay, or other modules.
Skills and Tools
You will need some minor abilities and tools to accomplish this fix.
Tools include:
- flat head screwdrivers,
- a soldering iron and solder
- and (preferably) a magnifying glass or similar.
Mcc mortgage credit certificate program. You will need to be able to remove the plastic cover below the steering column housing and then remove the Electric Window Module (ECM) and its cover.
You will need to have some ability with a soldering iron, including removing old solder and re-soldering existing joints.
How to Take Out the Electric Window Module (ECM)
The location of the ECM is exposed by removing, on the driver's side, the plastic front panel which covers the fuses, and the lower cover. The ECM is clipped onto a plastic backplate which is clipped onto the side of the heater tower (see photo 1 below). Removal may damage the plastic clips, but that is easily remedied later. The separate lower wiring connector can be twisted off the backplate. Remove the ECM wiring plug to free the ECM from the car; note that the plug has a locking clip.
Open the ECM by using a small flat screwdriver on the black plastic clips just visible on both sides of the pale green coloured cover in photo 2 (yes, the poor colour rendition shows it as cyan). The cover clip holes can be filed slightly to assist future dismantling.
Identifying and Fixing
Inside is the ECM is the printed circuit board with components on one side and the solder joints and tracks on the other. Check the component side for burn marks or melting. If these are present, there may be an associated track burn or soldering fault that can be repaired. However component replacement is beyond the scope of this repair.
Check the soldered side of the circuit board carefully, preferably with a magnifying glass. A typical dry joint is shown near the centre of Photo 3 (close-up below of the printed circuit board), and is the most common fault. There may be more than one dry joint. Once you find it, it may be necessary to remove the old solder and clean it up before re-soldering the joint with flux-cored solder.
How to Check and Reassemble the ECM
Re-assemble the ECM and try it out temporarily in the car just by plugging it back in. If it still doesn't work have another closer look for circuit board faults.
If the ECM works fit it back into position, using a tie-wrap (as shown in Photo 1) if the backplate clips have expired.

Forgot to mention my window fault was a peugeot partner van year 2002
Followed your instructions
You do need a magnifying glass to see the dry joint as pictured.
I did an apprenticeship back in 1964 and used to inspect wiring on telecom for BT or as it was back then GPO.
The dry joint was on one of the connections on the Printed circuit board (PCB) of Two small Copper wired coils. One for each window.
Had the tools for the job and carried out as your instructions.
Window is now working as normal. Thank you for a great explanation.

I have the same problem with a 2013 plate berlingo but am told that ecm is different in 2013. have had several trips to garage and blown 5 driver door switches. garage refuses to change ecm and refuses to check dry joints.
