Two electric windows to four upgrade

[fourwheels]

Hi I have a focus 2008 1.8 TDCi diesel estate with front electric windows. Is it possible to add electric windows in the rear? Is the wiring already in place in the doors? How much for the mechanism. I'll fit myself.

Thank you.

I don't think the wires are there you would need to up grade the door cards as well

I think this would cost to  much to do

Thanks for that. A bit of wishful thinking that they might be standard fitted but it does seem as if it would be expensive. The rear winders are not to hard to reach from the front either.

Thanks again for replying

The 4-electric window system (comfort windows) is completely different from the 2-electric window system. 

Literally all parts  (including the front electric windows) are different. The 2-electric windows are conventionally controlled by switches and relays. The 4-electric windows system is CANbus controlled. Even the wiring is completely different.

Thank you for that added info. Always been good with mechanics but electrics have been a more 'mysterious' area. I'll just reach through to them. 

Thanks again for pointing that out.

I have most of the parts. £600 if you collected.

Only part missing is the floor loom if you don't have the wiring already there. To check you can either take out the door loom from the a pillar and see if the extra connector is taped up or find out what wiring your car has for the floor.

8M5T-14014-DEB OR DEA both support this but the car also needs to be a 5 Door, Keyless start and Parking Aid.
