Heeeelp.
I have recently bought my first Lotus, a ?66 Elan S3 s/e dhc. Unfortunately the electric windows aren?t working, however the previous owner advises they were both working immediately prior to collection; a lovely lady who I have no doubt was telling the truth. Could you assist please with troubleshooting?? Cheers, Kev

If they were both working, and now both failed, it is most likely the supply to the switches. They share a common supply, and after the switches are quite separate. If the wiring is original then I think from memory the fuse is common to many other devices. (not got the diagram to hand) but some cars may have had extra fuses fitted.
The wiring behind the dash is not fun to get at, but if you remove the plastic trim along side the switches you should be able to get a meter to the switches.

On my Sprint the Windows are wired so they can go down with Ignition off BUT to go up the Ignition must be switched on.
Are you saying they don't work with the Ignition switched on

That's a pity i thought i had the answer for you.
Maybe try a temporary Earth wire direct from Engine Block to Earth Wire on window Motor.
I have found problems before where the Wires going through the Door Hinge looked good but Wire Core had broken inside. Leaving the Insulation in perfect condition.

I seem to remember from when I had an S3 that there was an earth wire that goes on one of the bottom dash board screws (there are two screws that secure the bottom of the dash board to the centre bracket above the gearbox which is bolted to the chassis) the two screws may be hidden by the centre consul.
As I recall it has an "eye terminal" on a black wire, I think that is where the window motors get their earth, think my eye terminal was on the drivers side screw but check both sides.

Funny..I?ve just bought an S3 FHC and my drivers side window failed in the down position. Checked connections to the motor unit located at the base of the door and all looked good. Then checked out the other end with ignition switched on and found by removing the window switch securing nut on the dash side and then manipulating the switch barrel in and out got the window working again..Clearly an intermittent fault .. but looks like by chance I have isolated the route cause of the problem to the switch or it?s connections.
Not sure this will help solve the double window failure listed in the original post, but hope it is of use to note.
