SMITHLEXUS

Hi, I have read some of the forum posts on this site, and my problem is this; when I turn my ignition off my headlights come on! they are the Xenon type (they were fitted with the car and are factory fit). When the engine is running everything is fine but as soon as the ignition is off the headlight lights remain on (no other lights at all just the two headlights) and there is nothing I can do about it. I have had the stalks checked and the relay switch checked, and no errors are reported on the diagnostics machine. I have had to take the relay switch out in order to cut the power to the headlights so the battery doesn't drain. I have spoken to Lexus Liverpool, and they state that although this is not a common problem, they have dealt with it before with this model. They stated that the fuse board near to the drivers foot well needs replacing and the ECU. This is probably due to water ingress from the windscreen area, which has corroded the fuse board. I have had a brief look and there appears to be no water in the fuse board / foot well area, even after pulling all of the trim out and having a good look, even drying it for an hour or so with a hair dryer ! Why do both parts need to be changed? Can you change the fuse board and not the ECU, or do they have to be changed together ? The quote today was as follows : Block Junction (fuse board) L82731-53011 £287.52 ECU L89220-53420 £241.23 2 HOURS LABOUR £160.00 TOTAL £688.75 As you can imagine I couldn't believe the price, and had to be carried out of the garage ! Does anyone on this forum know of any hints / tips solutions etc or decent garages (in the Liverpool ish area) were this problem can be looked at for cheaper etc.. Thanks in advance for viewing this post etc.... Smith

look at my post, I have just been told that water is slowly leaking through my wind screen and has corroded a main fuse board in the foot well (drivers side)... whilst you are working in the front area of your wind screen, check the seals round the wind screen.... to make sure this doesn't happen to you ... just got a quote of nearly £700 !!
