Go LPG! - Research

XJ 40 and X300 windscreen washer pumps often fail. They are difficult to get at, placed under the wing liner of the RH front wing. Once the inner wing liner has been released and folded down (the easiest way to do it) the pump can be disconnected and prised out of the bottle.

Now comes the real shock - Jaguar want Ł40 plus Vat for a replacement!

A little lateral parts thinking reveals that the washer pump from some Ford models are a pretty close match. Go to to a breakers yard and buy a couple for Ł3 or so. Cut off the donor car's electrical connector ot the pump as this may differ on your Jag, and CUT the rubber washer feed pipe, do not try and pull it off. This will prevent you from breaking off the little nozzle that exits the pump. The pipe can be removed later on by cutting down its side. If you can only find the more common twin outlet pump, the unwanted second outlet can be blanked off using a self-tapping screw and some silicon.

The way the pump 'points' when fitted in the Jaguar bottle may vary from the original but most will allow reconnection. Connect up the Jaguar wiring to the pump's connector and fit the supply pipe. If the pump works, your problem is solved. If not, try another pump!

New pumps (complete with the connectors to convert the car's wiring) can now be bought from us at Ł14.99 plus postage. They beat Ł40 plus Vat every time.

Dead repeater.....	Remove the offending lamp from the wing. (It might be a good idea to remove both lamps and repair them, saving another bout of trouble later on). Depending on the age of your car, the lampholders may turn and lock into the wing or be bonded with sticky foam. If you have the latter, carefully prise the holder out with a blunt tool (pref. plastic) and take care not to slip and scratch the paint.
Cut the wiring as close (long) as possible	With ignition, indicators and hazard warnings switched off, cut the wiring though as close the base of the bulbholder as you can. Make sure that the remaining wiring cannot disappear back into the wing aperture as it'll take ages to get it back out. If in doubt secure it with masking tape or similar.
Here's some I prepared earlier........	Indicator repeater bulbs and holders from a Mk 4 Ford Escort (there are many similar options from different manufacturers) bought from the local scrapyard, a bargain at Ł2 for 4....... Check them for condition before cutting them off the car's loom, only choose the ones with no corrosion on the bulb contacts. Leave the wire tails cut as long as you can. Back at base, test them (and therefore the bulbs) across a battery before commiting to fit them.
A nice tight fit will ensure the bulbholder will not fall back out later.....	Using long nosed pliers, remove the old bulb and the remains of the bulbholder contacts from inside the holder. Now you have a nice empty plastic bulbholder unit, but nowhere to fit a bulb. Drill and file the end hole out to almost the same size as the remainder of the tube, just large enough for the replacement bulbholders to fit snugly. If you filed too much out and the bulbholder is now loose in the body, wind some insulation tape around the bulbholder to increase its diameter and acheive a nice tight fit.
Check the lamp works before refitting!	Connect to the original wiring using good quality crush clips (Soldered joints are better) and shrink wrap. I don't find the combined crush/shrink items anywhere near as good, but if that's all you have then they'll do). Check that the lamp works before you refit the unit......On at least one occasion it didn't and I had to cut the wiring again, to a point beyond the original loom connector plug as that portion of the wiring was corroded and not making contact. If all is well you are ready to refit the lampholder assembly. If you have a later car, the base can be stuck back on the body using clear silicon sealant or similar. If it moves after positioning, fix it in place with masking tape and leave overnight.
	Now refit the lens (remember the chrome bezel goes on first). Test the lamp. With a little luck your efforts will be rewarded by a nice bright flashing lamp. The repair cost is .50p per side, and better ..... The next time a bulb fails you may even be able to change it!
