I can confirm that MK1 KA window regulators can be used. I wrote an article, published on Quantum Mechanics Issue 95 (Autumn 2018) explaining how I fitted them in a 2+2. Later I Andy Heaton and I fitted some to his saloon. The link Steve provided shows how to shorten the runner. The other issue is the KA regulator cables are shorter than the Mk3 Fiesta 3 door units so the motor mounting holes need to be relocated.

All 4 cores seem to have god continuity so at least I don't have to replace that as it looks like a pig to do. Not sure if my window switches are Ford - they look like the generic rectangular electric window 5 pin switch with spade terminals - maybe they have already been replaced once. I have not measured the load motors draw but my early version copy of build manual show 30A fuse on supply so relays seem a better way than direct - as you say need 2 per side Looking at regulators I can now see mine have the 90 degree bend at bottom (what a bodge solution that was LOL) so most likely a failure waiting to happen if not already in progress! I recall seeing a drawing detailing window mods (I think you were the authorJim) but cannot find it now. @Martin The KA mk1 units look like the best option to me - easily and cheaply available and newer. The cable sections are shorter than the the Fiesta MK3 so the motor mount position would have to move but that is easy enough. Same motor reverse polarity operation via switch (or relay in my case). With regard motor change I think it should be possible (but probably not cost effective) - the motor just drives a worm gear but that of course needs to be same on both units. I have taken regulators apart before to replace cables - most of them just wind the cables around a grooved nylon drum. I think in theory you could shorten the cable instead of fitting spacer on sleeve (need to solder on new nipple in correct place). I have now confirmed that I have the 90 degree bend units so these definitely need to be replaced.

The wiring is 2 core to each motor, and the polarity is changed by the switch for either up or down motion. I’m pretty sure it’s not possible (or certainly very difficult ) to just change the motor unit because the lift wire is coiled within a geared housing attached to the motor – If you are brave enough to dismantle an existing unit from your car it may answer whether a motor swap is possible. I changed to electric because my manual winders had the ‘bend the track’ modification, which is ultimately doomed for failure because the lift wire cuts into the track – If the tracks on your car are modified in this way (bent 90 degrees) that could explain the slow movement. If it is helpful, the conversion covering the parts needed and how to make the changes without bending the track was in issue 176 (March 2021) of Complete Kit Car magazine Back Issues [2] - performancepublishing.co.uk <https://www.performancepublishing.co.uk/back-issues/page/2/> Regards, Martin Scott Sent from Mail <https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10 From: [email protected] Sent: 25 May 2022 14:50 To: Quantum Owners Group Subject: [Quantum Owners] Electric Windows I have recently been doing quite a bit of rewiring on my saloon (factory built). I noticed the wiring cable for electric windows (looks original) is 4 core (Red white black brown) going from cabin into door cavity but at each end of this cable 2 pairs are joined so effectively 2 core cable connecting motor to centre console switch. Wondering why 4 core cable was used in build? - possible wiring of extra door switch? . The wire gauge looks same on 4 core and switch connection cables so extra load capacity seems unlikely. Currently the switches are wired directly (no relays). New switches and relay operation are going to be fitted. Window movement is really slow. I don't think this is due to dirty glass friction etc. so maybe motors are tired. The current setup is using Bosch motors which I guess is probably Ford Fiesta Mk3 original type (see pic). If the mechanical side of regulator/cable is ok I was wondering if just motor can be replaced on these? (a lot of Bosch units look very similar although slightly different part numbers) If I replace complete regulator with motor which donors have owners found best or easiest to fit? I think originally modded Fiesta MK3 units were fitted but others have mentioned MK4 MK5? can be adapted as can Ford KA units.
