Did mine a couple of years ago & cost under £100.
Fairly simple job, 30 minutes or so but I can't locate the thread at the moment.
Electric door lock actuator (Drivers door on mine) had to be purchased from Lexus & was approx £130.
(Slightly annoying as it was only a small 12V motor that was faulty, but non repairable without destroying the housing)
Again it takes about 30 minutes. (always quicker if doing jobs for the second time) :winky:
Good luck with your repairs & finding the fuse.
Regards,
Max.
Thanks for that Max, some guys on the US forum have bought the small motor you are talking about and done the repair for £1.50 but I have not been able to get a motor over here without knowing some details about it regards size etc. there a write-up with instructions on how to do it.
