Jaguar S-Type Wipers Not Working, Wiper Linkage
When S-Type wipers slow down, stop part way across the screen or won't park, the motor is usually fine and the spindles are seized. Water sits under the pivot caps and rusts them into their sleeves, worst on early cars that stand unused. Free and grease the spindles first; if they're too far gone, buy the motor and linkage as one assembly.
How bad is it · Garage, carefully
Don't drive in rain without working wipers
A wiper stuck mid-sweep blocks part of the view and fails exactly when you need it. The motor keeps trying to reach park and can flatten the battery overnight, so pull the wiper fuse until it is fixed.
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.
Seized spindles: free them and grease them
Each arm sits on a splined spindle turning in a sleeve under the scuttle. Water collects under the round caps at the arm nuts and rusts the spindle into its sleeve, and the motor has to fight it: first the wipers slow, then they stop part way.
Wipers slower over a few days, worse after the car has stood, then stuck near the middle of the screen with the motor still audible. A healthy spindle has a trace of up-and-down play; the seized one has none.
Stop the wipers mid-screen, lift the cap at the base of each arm and move the arm by hand. If the splined spindle moves with the arm, the linkage under the scuttle is next.
Take off the arms and the scuttle trim, remove the clip and washer on each spindle, then soak and work it with penetrating oil while cycling the wipers, tapping lightly until it turns freely, and finish with waterproof grease. For a stubborn one, build a little dam of putty round the base, fill it with light oil and leave it. Don't force the arms: the square spindle end rounds off.
Linkage past saving: a complete motor and linkage assembly
When a spindle bearing collapses or the linkage has rusted solid, freeing it either fails or doesn't last. Buy the motor and linkage as one assembly on its frame: a motor on its own is the wrong purchase when the linkage is what has failed.
Freed spindles seize again within weeks, a spindle has collapsed, or the motor runs when fed directly but does nothing on its own plug.
Separate the motor from the linkage and move the linkage by hand. If it won't swing freely through its travel, the assembly is the fix.
Fit the complete assembly and grease it. On pre-facelift cars the strut brace and coolant expansion tank have to move, and the motor comes off its frame to clear the brake servo; the soft M8 strut brace bolts shear easily, so soak them the day before and work them in and out. On facelift cars the whole assembly comes out in one piece with the motor in place.
Wipers that won't park or won't switch off
A park circuit inside the motor assembly tells the motor where to stop. Play at a spindle, or a park contact on its way out, leaves the arms short of rest or running on with the switch off, and keeps the electrics awake.
The arms stop an inch or two above the rest position, run on after switching off or with the ignition off, or twitch now and then; the battery goes flat.
First make sure no spindle is half-seized. Then see whether a gentle nudge at the park point makes them stop.
Worth trying: free the spindle, and take up play with a thicker spacer under the clip on the spindle. If the park circuit itself is failing, the motor assembly is the cure.
Wipers that cut in and out: relay contacts
The wiper relays live in the fuse box under the bonnet. Dirty or corroded contacts on a relay or in its socket drop the wipers out and let them back in.
The wipers work for a few minutes or an hour, stop, then come back.
Pull the wiper relays, clean their pins and the socket, and push them firmly home.
Worth trying before anything else on an intermittent fault.
Fuse blows when the motor is plugged in: a short in the harness
If the 20 A wiper fuse blows the moment the motor connector goes on, and a new motor changes nothing, the current is going to earth in the wiring between the motor and the engine bay fuse box.
Washers work, wipers are dead, and a new fuse blows as soon as the motor plug is connected.
Pull the park relay and fit a new fuse; if it still blows, test the loom for a short to earth section by section. The column switch only signals the front module, which drives the relays, so suspect the wiring before the module.
Repair the chafed section; the main fuse box has to come out to reach it.
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.

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.
