Hi all
I have a 2010 Fabia 1.2 HTP
My central locking started behaving strangely, then later the electric windows stopped working. This happened in the queue to a Macdonalds drive through!. I couldn't open the window to pay, then I found the door wouldn't open even using the unlock button, fortunately I have manual rear windows so had to climb in the back and wind down the window to pay. Then I had to climb out of the back window to get out and use key to open door.
I searched the net found this website and discovered the common door wiring loom problem. I had a look at the loom and sure enough there were a couple of broken wires, I soldered them back together just to see if that fixed the problem. It did fix the windows but the central locking was still being weird. That turned out to be two faults, the first was bad contacts in the door lock mechanism, the second was green corrosion on the pins on the connector to the window motor. This last one made everything go back to normal and it's been working fine for the last 6 months.
I was surprised to find the furry greenness on that connector as its not inside of the door but is behind the door card!
