My car started doing that about 10 months ago intermittently. About 5 months ago, I put in a new bulb. It still works.

 

If it's blowing a fuse, it sounds like you've covered both terminals with one piece of foil. This will cause a short circuit.

 

A report back. I now have over 50K miles on the tin foil repair. Not proud of it but it does work!!

Sounds good to me!

 

I have had the same experince with signal and park light failures. At first I used a pocket knife blade to lightly clean the bulb & socket wires. This worked temporarily. Next failure I cleaned all connections and pryed the bulb wires up out of the seat a little and this worked even better. The last time I cleaned all connections with emery cloth, carefully pryed the bulb wires up and slipped foil underneath to keep the wires from completely settling back into the seat. Then trimmed off the excess foil and re-assembled. No problem since.

I temp fixed my right front turn signal by using the fix that Tbird6 described. I took a small, single, corner piece of foil and wrapped it around the lead on the bulb that would touch the copper lead. That will fix my issue until my new socket comes in. I have attached two pictures to help someone with the fix.

 

That's it! Good pictures!

I sorta planned on mine being temporary until I priced a new socket. A used one might be ready to fail too.
So I have let it go.

Left front turn lamp socket melted on my 2006 as well. Nalley was able to ship me just the lamp socket from stock.

 

How much was it?

 

Even with the forum discount it was about $50. However, given the astronomical cost of the complete plastic headlamp assembly, I was not willing to drive around with the auto equivalent of a "penny in the fuse socket" (you have to be of a certain age to remember screw-in house fuses!).
The part # is XR855196 (on my receipt but they spelled my name wrong so you should verify that!)

 

This is the correct part number.

 

Interesting??

I have different part numbers for the socket?

XR812401 Right front turn signal socket
XR848363 Left front turn signal socket

The Jaguar XR855196 part covers 1999.25 - 2005 S Type production years from what I understand. 2006 + are different part numbers.

 

Just an FYI:

My turn signal would go out the day after every rain here in SoCal. Then, like many of you, I cleaned and covered the slightly burnt contact inside the turn signal socket with a piece of heavy duty foil and then installed a new bulb. I've driven over 20k miles since and it's still working.

In general, could this be the cheapest repair in Jaguar history?
