Hi,

I had a heated windscreen in my 98 XK8, which sort-of worked ( most of the bars weren't heating, but you could see it was trying its best ).

Since I had a new heated windscreen fitted ( you can see the heater lines ), it doesn't work. The only thing that's changed is the windscreen was replaced, so I'm assuming it should be simple to get it working again.

Can somebody tell me what fuses to check and where the windscreen plugs in? I'm wondering if the Autoglass guy forgot to plug the window in. Also if there's anything else.

Thanks.

PS: If I posted this the other day, I apologise. I definitely intended to, but I don't remember doing so and I couldn't find it when searching the forum.

 

Chuckle. My XKR had a cracked windscreen, so was an automatic MoT failure last week.

Got the windscreen replaced by the garage as part of the pre-MoT service but (on the first frosty morning after the MoT, i.e. two days later) found just the passenger side worked. Took the car back to the garage to get it swapped. We are now on windscreen number six 'cos the continuity in the screens is really poor. Also, the tags on the windscreen that couple with the car electrics have been damaged on at least two of the replacements we've been given. Seems to be two systematic faults: one with the manufacture and another with the logistics chain of getting the windscreens to the suppliers.

If the screen was part-working before, my experience suggest the problem lies with the new windscreen and not your car's electrics. But it is worth checking the fuses all the same.

[The garage are handling this for me, so I can't answer the inevitable and wholly reasonable next question of: "which fuses might they be and where"? Sorry.]

Hope you get it fixed.

Best wishes, Colin

 

My initial thought is that the guy probably forgot to plug the windscreen in, but I have no idea where that is.

 

I'd also suspect a wiring fault but the windscreen heaters are independently fused left and right:




They also have separate relays:

I've taken a picture of my passenger side dashboard fuse box - the fuses aren't numbered.

Also, there are no 30's in there. I'm wondering if I was wrong that the heated windscreen used to work.

Any ideas chaps?

 

I think there's confusion between passenger side fuse box in the engine compartment, and passenger side fuse box at the end of the fascia. The table in Graham's post says "engine compartment" but the picture is of the fascia fuse box.

 

Thanks, I'll go and take a picture of that one and compare.

 

Do you mean this one? This is to the front of the upside-down plastic cup looking things, on the passenger side ( behind what I believe to be the ABS module).

If there's another fuse box in the engine compartment, I couldn't see it, but the ones labelled 15 and 17 had less than 30 amp fuses in them ( I can't remember which ones now ).




Sorry about the blur, I think my phone is drunk.

 

Failing any of the above and assuming that the windscreen replacement was fairly recent, why not take it back to Autoglass?

 

I'm booked into the garage next Monday for a couple of other things - I've asked them to take a look while it's in there. If it turns out to be the windscreen, I'll call them then.

Before next Monday, I'd like to have a look at the fuses, if I can work out which ones and get it fixed sooner rather than later.

 

There are TWO fuseboxes in the engine compartment - both on the passenger side (on UK vehicles)
There's the one you found, and there's another which is under the plastic cover within the "bulkhead extension" (where the ECU is) which (I think) is the one you want.

 

here is the box it has a cover on it when you find it

 

since you've been taking pics....would you mind posting a pic of the on/off controls for this option....I was hoping my '01 vert had this feature but see no switch, only a 'blank' that looks like it may be a place for such switch...thnx-JD

 

Jazz Cat: The button for the heated front windscreen is the F button next to DEF on the bottom left of this image:



That's a 1998 XK8, but I assume the symbols will be the same in a 2001.

 

There certainly is confusion - and I'm the one causing it!

The information on fuses and relays in my post #4 is correct but as David points out, I've shown the wrong fuse box. The correct one is B circled in red:

I finally found those fuses and they both look fine. I'll have the mechanic give it a once over on Monday and failing that I'll call Autoglass.

I checked my receipts and the windscreen was fitted in August, so I'm well within any warranty period.

 

I'd suggest getting in touch with them sooner rather than later though

Good luck and hope to hear.
