Instead of paying commission to the garage on the part and then paying the labour as well I decided to order the part myself and replace the mechanism on my own.
Bhpian vaibhavyagnik recently shared this with other enthusiasts:
This DIY is about replacing the window mechanism on drivers side of my Skoda Octavia.
My work place has a lot of security gates and I have to punch to open the security gates atleast 10 times a day. Probably the frequent operation coupled with poor quality of after market part led to failure of door winding mechanism on drivers side door.
When the mechanism failed, I immediately went to my FNG. They did not have the mechanism in stock but they fixed the glass in place using metal wires.
Instead of paying commission to the garage on the part and then paying the labour as well I decided to order the part myself and replace the mechanism on my own.
The tools require for this DIY
1. A good quality screw driver with interchangeable bits. It should have a magnetic extension also.
2. T30 Torx bit
3. T20 Tox bit
4. 10mm open spanner
5. Cable tie cutters
6. Plastic trim removal tools of good quality
The DIY is divided into 9 main parts
1. Remove door card
2. Remove electrical connections on the door
3. Remove glass
4. Remove window mechanism
5. Install window mechanism
6. Install glass
7. Test the fitment and operation of the glass
8. Restore electrical and mechanical connections on the door
9. Install door card
1. Remove door card:
• Pull out the trim at the bottom of the door handle
• Remove the rotary mirror switch and remove its electrical connector.
• Remove the window switches console by inserting trim removal tool and remove its electrical connector
• Remove the 2 T30 Torx screws
• Rotate the black plastic tab at the bottom of the door card so that notches align.
• Using a plastic trim removal tool, pry on the left, bottom and right side of the door card to remove the door card from the door.
• Disconnect the tweeter, the lock led, the door release cable, and the red stop light at the bottom of the door card
• The door card is now completely detached. Keep it safe
2. Remove electrical connections on the door:
• After the door card is removed, you will see the window motor and the module which sends the command to the motor. The module has 4 connections. Remove them carefully. Most of them have a locking mechanism which involves pressing on a tab and releasing the lock. Detailed instructions on each connection in the video.
• Remove the electrical connection of the motor. Detailed instruction is in the video.
• Remove the motor by unscrewing 3 T20 torx screws.
• Remove the door latch cable from the water dam.
• Remove the water dam (black plastic) by using a trim removal tool.
3. Remove the glass:
• The glass is held in place on the rails by plastic tabs. You will have to wind down the glass and release the tabs to release the glass from the rail.
• Pull the glass upwards and outside to remove the glass from the door and keep it safe.
4. Remove window mechanism:
• The rails are held in place by 2 bolts on each rail. One at the top and one at the bottom. These bolts are 10 mm.
• If you removed the plastic winding portion in step 2, then essentially the window mechanism is free inside the door. Using both hands grab the rails, rotate the rails anti clock wise 90 deg and pull out window mechanism from the water dam cavity.
5. Install Window mechanism:
• Ensure the correct orientation of the rails (the plastic latches should be pointing up). Rotate the rails anticlock wise by 90 degress, insert the window mechanism through the water dam cavity and rotate the rails clock wise 90 degrees.
• Align the rail bolts to the holes provided in the door and loosely fix all 4 nuts.
• Fix the winding mechanism by pressing the mechanism from inside so that all 3 screw posts jut out from the door.
• Cut the cable tie of the window winder mechanism
• Tighten all 4 nuts.
6. Install glass:
• Insert the glass into the frame so that the glass rests on the plastic latches of the window mechanism rails.
• You can see if the window is locked into place using the windows provided inside the door.
7. Test the fitment and operation of the glass:
• Fit the motor using 3 T20 Torx screws.
• Make the electrical connection to the motor
• Connect the switch console
• Connect the door module by making all 4 electrical connections.
• Test the fitment using the switch. Operate the window gradually at first as everything is loose and the glass might snag on a cable.
• If found correct, move on to next step.
8. Restore electrical connections on the door:
• Thread the door release cable through the water dam
• Press and fit the water dam in place
• Make 4 connections to the door module
9. Install door card:
• Hold the door card close to the door.
• Thread the cables out for the rotary knob switch and the window switch console
• Connect the tweeter
• Connect the door release cable to the handle
• Connect the LED
• Connect the Red warning light
• Press the door card in place after aligning all the locks
• Connect the cable of the rotary knob switch and press the switch back into its place
• Connect the cable of the window switch console and press the console back into its place
• Insert and tighten the 2 T30 Torx screws using magnetic extension of the screw driver
• Install the door handle trim.
Once everything is complete, tidy up the door card and test operation.
Happy DIYing!
