Update on this issue at last, main dealership have established water ingress from sun roof and water ended up all over loom connections behind glovebox, numerous pins/sockets eith covered in green corrosion or badly covered in blackish carbon deposit from arcing. All electrics cleaned up and issues with sun roof leak resolved. Everything now working correctly so will find out tomorrow when I pick up car.

Booked into Lexus dealership next week so let's see what they turn up. Car smells damp inside (apparently independent source advises me) and windows fog up heavily when car sitting so could be a water ingress related issue.

All cables connecting to battery and ground points were fully cleaned etc when battery replaced so hopefully they are OK. If it was a bad ground would it not perhaps causes issues with all electrical items. Spoke to another auto electrician yesterday who said he thinks there is an ECU in the drivers door which controls most (if not all the problem items) and it maybe that has bad connections or is failing. Can only tell once he gets car in and strips door out.

Hopefully will be something like that, nearest Lexus dealership 60+ miles away so not convenient but do have Toyota dealership about 5 mins away although they don't seem keen to look at it and even say Lexus loath to tell them anything anyway.

Tried that as well Pete, fully charged battery last night while disconnected?

It is a brand new battery only fitted 3-4 weeks ago and is fully charged, may look for a specialist garage in Dundee (unless anyone can recommend someone local to me) and get second diagnosis.

I have an 06 RX400 which started developing battery issues, i.e. after 4 - 5 days of non use battery was dead, had it tested and was faulty so new one purchased. Same issue continued and after investigation by auto-electrician it was discovered there was quite a large battery drain when car just parked. Was eventually traced to one particular circuit (fuse box in engine compartment) and when that fuse pulled drain stops. As a short term measure that fuse has been routed through an external switch so when car parked and locked, switch flicked and battery fine. I know this fuse operates the central locking and when car is started the on board computer figures for speed, mpg etc are at Zero and heater/air-con is switched to Off. Cannot discover what else if anything is on that fuse or which particular circuit is at fault. Would putting on a Lexus dealership computer system be able to investigate right down to where fault is? Added to this when I started car yesterday & today the switches on the door only operate the drivers window (others work independently and have even tried reset but no success), the mirrors do not adjust or fold, the seat memory system is dead, power boot won't operate and strangely the warning light for showing lights on doesn't illuminate?. I also have the dreaded Check Hybrid & Check VSC messages and symbols. The car actually drives perfectly round the block and everything else electrical seems to work fine. Anyone able to tell if all these could be connected/related, I have 2,3 or even 4 separate issues. If another fuse has blown which one and where is it??? Sorry for such a long post, thanks to all who survived to the end and believe me if I could have condensed it I would :-)

Have looked up Toyodiy but they seem to be based in Russia? Is there anywhere in UK that may have them? Thanks

Hi. I bought myself a Lexus RX300 in Feb (loving it so much) but I think there is a panel missing from the front which ruins the look of it. Cannot find any other ones round here (Dundee) to compare with and no local dealer to ask. Have searched E-bay, breakers etc but not 100% sure exactly what I should be asking for :-( I think it may be part No PZ415-K091-00. Hopefully one of you experts can point me in the direction of a reasonably priced replacement. Car is a 2004 model. Couple of photos attached to show what mine looks like. Thanks. Gill

Hi Guys & Gals (of course). Going on from this, I have the 2 sets of wireless headphones but the foam ear covers are falling apart. Anyone know where I can get a new set from or are they general ones I could get off E-Bay or the like? When I took one off it is slightly oval in shape so cannot tell if meant to be that way or are round ones that have just stretched. Thanks in advance Gill
