Adding One-Touch Window Control to Passenger Side
For a good while, in-fact several years I have been annoyed that the Punto along with most other cars does not feature one touch control on the passenger window. For context the place where I work requires passes to be shown regularly throughout my route to and from work. Many of these pass check points are little huts on the side of the road and I have to wind my passenger window down to show my pass. Annoying as hell having to pull up and hold the window switch whilst stopped when there is a backlog of traffic behind me. So I decided to do something about it. Turns out it was quite a lot of work, but to me it was worth it. The value it gives me was worth persevering.
I was exploring the web looking to see if anyone had done the same, unfortunately a lot of modern cars have the window switch hold on function built into body computers etc. The Punto, if it has it, has the driver's one touch function built into the switch panel on the centre dash. Then I came across this site: https://www.ford-trucks.com/forums/116804-automatic-window-conversion.html#post809817
It's a post from 2003 about adding 'express down' window controls to old ford trucks. The item they specified is a fancy hold on relay from Mustangs and Crown Vic's etc. F2DB-14B118-AB is the pt. no.
This is more like it, some old school standalone relay logic. This item isn't available in the UK or Europe and quite obsolete. So a Google search of the middle part gave a result of a module fitted to UK spec Transit Mk6 and Mk7 vans. F3LB-14B118-AA is the part we want. I got one, well two of them for about £12 each off eBay. On taking one apart the internal function is the same as the American part. Must be a cheaper updated pt no.
My idea was to gang two of the modules together to get one touch up and one touch down function.
Then I purchased a metre length of 2.5mm electric flex so I could strip the individual cables out and have some good thick gauge wires in different colours. I'd calculated that with the window fuse being 20A i'd need at least 14 AWG, I was wrong more on that later.
