Hi all,

I'm hoping some of you can help. A few months ago, I changed the LEDs that had blown on my 1997 XK8 Convertible's switch pack (the one with seat heating / hazard warning etc) Recently, I noticed that the four right hand switches weren't illuminating with their new bulbs so I opened it again to make sure that the bulbs were in tight. Very stupidly I used a screw driver while the ignition was on (yes - I know dumb!) and there was a small spark.

All buttons work, but the panel has lost its illumination totally now. I've checked all fuses and opened up the switchpack (no sign of damage) but from what I can see there is minimal circuitry in there anyway. Whatever I blew is elsewhere I guess. Any hints please?

Thanks in advance,


Russ.

 

Double check fuse number 15 in the fusebox on the passenger side of the dashboard (fascia).

 

Double checked it. Sadly, its definitely intact.

 

Also, I think LED bulbs must be in the right direction if two sided. I changed a bulb and I simply had to turn it around.

 

I'll give that a try though all of the other LEDs in the pack now do not light up after the spark whereas half of them did before....

 

Ok - rotating the LEDs didnt help. Anyone know which ECU I've probably blown/damaged please?

 

It's very likely the instrument pack itself. You can send it out for testing and repair, but it might be cheaper to buy a used one. Just match the numbers.

 

Although there is a very slight chance it is the instrument pack, I think it is much more likely to be the dimmer module. See location below in RH side of dash.

 

Steve, is that diagram for a RHD?

 

Actually it is LHD, but the dimmer module location is the same on the RH side of the dash in both models.

 

Turned out it was the instrument pack after all. I bought a refurbished one for £63 delivered next day and a dimmer module just in case (got it for £20 so worth a gamble)

Thank you all - I won't be so silly next time!
