I'm wondering if anyone can help...

It appears overnight my interior courtesy light, front and back of my x type has stopped working. As has the lights on the vanity mirrors on my sun visors.

Also the heater dial has stopped working so I have only hot air, and lastly the dial that directs the air around the car has stopped working.

So all in all quite a lot has gone wrong overnight! I assumed this might be a fuse but I can't see anything wrong. I've seen mention of perhaps a relay failure but I can't see a guide anywhere to tell me which relays do what.

Can anyone suggest perhaps what I might try to fix this. I've lost faith in my local garage and feel sure that such a sudden failure of so much must be a fuse or relay.

I have a 2004 diesel x type jaguar. 2.o saloon.

Any help gratefully received.

Thanks.

Wickes, you mention that you have a 2004. Unfortunately, there are 2 different electrical layouts for that year car. Just to confirm, your car was built in/after April 2004 (this date is written in the driver's door jam area on the sticker there by the latch). From the sounds of things, you have blown fuse F35 in the passenger area fuse box. If that fuse is good, then most likely you have a bad GEM module as that is the only other common thing to what you are experiencing.

If you have an earlier model car, then you are after fuse F25 in the power distribution box (engine bay).

 

Thanks Thermo for the reply - I'm very grateful! Let me take a look and see if I can find that sticker you mention and I'll come right back. I can't see anything there at the moment so it might be that I need to look at the documentation that came with the car to see exact date of manufacture!

 

Hi Thermo,

Is this the sticker you were referring to? I don't see a date listed on it sadly. Does anything here mean anything to you?! Are you able to decipher this and get an exact date?!

Thanks...

 

according to the web site below The 10th character of the vin is the year.
Looks like you have an 05

What Can Your Jaguar's Vehicle Identification Number Tell You?

 

Thanks Paul - I think you may be right.

It's a UK '54' plate which I think means it was registered between September 2004 and February 2005.

Number plate format | AA

Thermo - do you think this points towards FUSE F35 in the engine fuse box?

From the handbook this is the Direction Power Module? Is that correct?

 

Wickes, yes, that would point towards Fuse 35 in the PASSENGER area fuse box.

 

Thanks Thermo! I'm very grateful for your help - I'll check tonight. If I can fix this myself I'll be delighted - the garage has already spent 3 hours on this and is convinced I need to buy a new interior light at £300.00!

 

Ebay has one for 5 GBP

or 20GBP for the front one

Thanks Paul for the ebay search - it's rare that the front lights come up in that colour (the right colour for my car) so I'll definitely take a look at that.

Sadly fuse 35 was fine when I checked it. I replaced it for a new one just in case but still I have no interior lights / vanity mirror lights etc.

I wonder if it could be a relay? I've seen some threads pointing towards a battery saver relay as sometimes being problematic in this regard?

Anyone have any thoughts as to what to check next?

Thanks.

 

I think you might find it's F49, 10A in the Glove Box Fuse Panel.

You really don't want it to be the Battery Saver Relay as it's a permanent part of the fuse panel and not just plug-in!!

 

Thanks Astromorg - I just checked F49 and sadly that appears to be OK also. I'm starting to think this might be more serious after all.

If anyone else has any bright ideas I'd be very grateful, but otherwise I may have to bite the bullet and take it into Jaguar!

 

Wickes, do you have a multimeter? Do you know how to use a multimeter? This is sounding like we need to get into actual measurements to see what we have to make more sense of what is going on and to make "this is good, this is bad" measurements.

If you don't know how to use a multimeter, ask around and see if any of your friends do. This will make things a lot easier to figure out what is going on.
