Hello and heeeeelp ! Got into the car last week to find battery flat. Jump started but same problem next day. Assumed it was the battery (factory original), so bought a new one. Then noticed that, on switching engine off, climate heater blower still blowing, even when the car was locked up. Used the "off" switch and got round the issue but Lexus Birmingham had no ideas. On friday the problem suddenly cured itself. Got into car today, battery dead, so jump started again, this time no audio, climate or satnav, but clock still working. PCB fault ??
