Right I am currently in possession of my old man's xf 89 ute.

This started off life as a gls and at some point has had an ltd interior swapped in.

When the power windows were added they were done custom off a direct battery feed and some three way switches.

Issue I'm having is that the drivers window refuses to go up or down. Sometimes slapping the door trim will make it work for a second or so.

So far I have tried lubeing up everything and replacing the switches. When this didn't work I pulled the door trim and grabbed the trusty millimeter and checked all switches and wires and guess what 12.6 volt where its supposed to be and grounds where they're supposed to be as well.

With the window still not working (direct battery feed to the up output wire) I then tested the wires at the regulator and there's power and ground there too.

Motor is not even trying to wind window up even with full power half a centimeter from motor. After this I have stripped the motor down and cleaned all contacts but still no response from motor. Sometimes it just works and when it does it operates perfectly but even with motor disconnected from winder mech it still won't go.

Has anyone got any ideas this has got me stuffed there is no circuitry on the motor I can see it looks like a direct feed to the motor itself. It has ford xf motors and regs just like you'd fInd stock it's just the wiring which is different but since that has all tested fine I have no idea.

One thought I had was that motor has simply burnt out but it seems they are increasing hard to find.

Any and all suggestions are welcomed and much appreciated to get this old girl operational again. Especially considering its pissing down rain for the foreseeable future.

new through crash replacement parts suppliers

Can you be specific like provide a link I tried Google but apparently my googling skills need improving

xd-xf,zj-zl will all fit or ask at most wreckers as alot also do non genuine replacement parts, or ask at your local panel and paint.

So you've applied 12v directly to the motor ??
Checked continuity of the armature while apart too ??

They do have a thermal cutout IIRC, might be open cct.

Have applied 12 volt directly to motor same result ie nothing. The rest is getting beyond my experience

So get another motor as suggested.

Are you hearing the motor run, but not doing anything? - if thats the case then the 3 rollers (and possibly the larger wheel) need replacing (Ebay, $notmuch).

If not, then the motor itself is fubar. Like suggested here - get a motor from wreckers.

Ive seen similar motors for (Explorers I think, and F Series?) still available in the US, but never been able to prove they'll work. In any case - there are only two types of motors. If you take a photo of your original one you might be able to grab a rear one from an LTD or fairlane or something with low miles on it. Make sure you get the right orientation one.
