Hi PB_54
Nice to see another member from Redditch joining; have quite a few here now
I can't answer all your questions but for the ESP fault, did you check the brake fluid level? If it's around minimum, it could trigger these type of errors.
The wipers I believe can only be enabled again by the dealer.
The problem with the rear window sounds to me like the force limiter on the motor. For security reasons the window will partly open again if there is too much resistance while closing. Did you try to clean the window and rubber seals and lubricate the seals (special stuff is available from Halfords).
The fans for the 2nd row are located on the left and right hand side under the dashboard. When you open the front doors you can see the outlet, as the door is actually used to "tunnel" the air to the back rows.
I expect your dealer to be the local Redditch dealer B...lyn ? Which would explain the quality of repairs... I've had a Ford Galaxy from the same dealergroup... never again...
