Jaguar S-Type Window Problems, Window Regulator
On the S-Type, a window that drops into the door, crunches or stops halfway is almost always the regulator — its cable or a plastic clip lets go, while the motor is fine. A Lincoln LS regulator fits the front doors for far less than the Jaguar part. If the window still works from its own switch but not from the driver's, look at the switch pack and the door wiring instead.
How bad is it · Safe to drive
Safe to drive — but a dropped window won't keep out rain or thieves
Nothing mechanical is at risk beyond the door. Get the glass up and wedge it before the car stands outside — rocking the switch while lifting the glass by hand often gets it closed.
Which one applies to yours depends on your symptoms, your model year and what has already been done to it.
Likely causes, most common first
Read the check cost before the odds: a free check that rules a cause out beats a likely guess that costs money.
A failed window regulator — snapped cable or broken plastic clip
The S-Type uses cable-driven regulators that hold the glass with plastic clips and run the cable over plastic pulleys. Once a clip breaks or the cable jumps its pulley, the glass drops while the motor carries on turning. These were a known weakness from new on early cars, front and rear.
Grinding, crunching or sharp cracks inside the door; the glass creeps or falls open; the motor is heard but the glass doesn't follow; a window that starts noisy and gets worse. If the engine revs dip when you press the switch, the motor is straining against a seized mechanism.
Door card off: a slack or tangled cable, a cable wrapped round the motor drum, or a white plastic glass holder snapped off settles it.
Replace the whole regulator — repair kits rarely work because the clips break along with the cable. For 2000–2002 cars the 2000 Lincoln LS regulator is the same part (for example Dorman 741-876 left front, 741-877 right front); at a Ford dealer, ask for it as a Lincoln part. On the fronts one stud sits about 3 mm off, so file that hole in the door into a slot. Rears are less certain — compare before fitting. Keep the old motor if the new unit comes without one; it comes off with a T30 Torx.
A new aftermarket regulator that wrecks itself within weeks
Some cheap Lincoln LS-pattern regulators leave the factory with the half sheave at the foot of the motor pillar fitted backwards. At full travel down the cable runs off its end and the unit tears itself apart.
A freshly fitted regulator works a handful of times, then grinds and fails just like the old one.
Lay the new regulator out next to the old one before fitting and compare how the cable runs over each sheave.
Correct the sheave or swap parts across from the original before fitting; a genuine Lincoln part from a Ford dealer avoids the gamble.
Works from its own switch, not from the driver's — the switch pack or door wiring
The rear windows can be run from the door's own switch or the driver's pack. If the glass moves from one and not the other, the motor and regulator are fine — the fault is in the driver's switch, its connections, or the wires crossing the door hinge, which crack with years of flexing.
A rear window goes down from the driver's switch but won't come up, or only comes up with the driver's door wide open. A blown fuse or a stuck command after a battery or fuse event can start it.
Try the window from its own switch first. Then work the driver's door slowly while pressing up — if it starts working at one door angle, it's a broken wire in the hinge loom.
Worth trying: unplug, clean and reseat the switch pack connectors; check the window switch ground; recheck that the fuses are the right ratings. A battery hard reset can clear a stuck command. A broken wire in the hinge loom needs splicing.
The remote won't close the windows — that's the key's job
On early cars the fob opens all the windows but won't close them. Turning the key to lock in the driver's door and holding it closes every window and the sunroof.
Holding unlock on the fob drops all the windows, holding lock does nothing.
Lock with the fob, then turn and hold the key in the driver's door lock.
Use the key for global close. On a 2005 car, holding the fob's lock button for a few seconds closes them as well.
Every window dead at once — the window fuses
Each window has its own 20 A fuse in the boot fuse box. All four dead together points at power or fuses, not four regulators.
No window moves from any switch, often on a car that has had accident or electrical work.
Check F4 to F7 in the rear power distribution box in the boot, then read the body modules for codes with a reader that knows Jaguar.
Replace any blown fuse with the correct rating and find what blew it.
The window motor itself
The motors are generally reliable; most windows blamed on the motor turn out to be the regulator. A motor is only suspect when the window is completely silent with power at the plug.
The window stops without warning: no click, no hum, no grinding.
Door card off, check for power at the motor plug while someone presses the switch.
Replace the motor only once the regulator and the power to the plug are proven good.
The order to check them in
The point of the order is money: each step either rules a cause out or makes the next one worth doing. Green is free, amber costs a little, red is the one to arrive at last.
Look at what it does and listen
Grinding, cracks or a motor that runs while the glass stays put means the regulator. Total silence means power, switch or motor. Note whether the window works from its own switch.
freeTry every switch and the lock button
Run a rear window from its own door switch as well as the driver's, and make sure the window lock isn't on. A small lock button can make a working window look dead.
freeFuses, if everything is dead
On 2007–2008 cars the windows are on F4 (left rear), F5 (driver's), F6 (front passenger's) and F7 (right rear), 20 A each, in the rear power distribution box in the boot; 2002.5 cars use the same slots. Earlier cars differ — check the fuse list for your year.
freeBattery hard reset
If a window obeys one switch and not the other, disconnect both battery leads and touch the two loose leads together for a while to power everything down. The engine may idle roughly for a while afterwards until it relearns.
freeDoor card off and look
Prise off the trim round the release handle, undo the screws under the armrest and unclip the card. A slack cable, a cable wrapped round the motor drum or a snapped glass clip settles it. Brace the glass up with foam or a wedge before anything comes loose.
freeFree the glass from the regulator
Move the glass until its pin shows through the access hole. The plastic pin is two pieces: drive the centre out with a 4–5 mm drift, then the outer sleeve. On refit, put the pin back in the glass and press the glass down onto the holder until it clicks.
freeFit a new regulator
Three long bolts and a nut hold a rear regulator. A front Lincoln LS unit needs one door hole filed into a slot. Inspect an aftermarket unit before fitting, and clip the wiring to the door so it doesn't rattle. Reconnect the door lock plug — forget it and the car shows a door open with the interior light on. Allow one to two hours.

The highlighted position is the one the procedure talks about. Pulling a fuse is a stop-gap, never a repair: check what the circuit feeds before you pull it.
