I left both fuses out overnight and this morning battery was showing 12.7volts. i put fuse 1 (20amp, heated rear window, central locking) back in and left car locked with window open so i could still access fuses without having to disconnect and hold door switch and left for 30 -40mins like suggested above. with this fuse back in it is only pulling 0.1 from battery. i went back out an hour after and still the same so no problem with that.

Fuse 2 ( 10amp,interior lighting, radio, clock,diagnostic socket, heater module however is pulling 4.5amps off. at some point someone has had the passanger door card off as its loose and the speaker doesn't work on that side so i'm guessing that its been played around with and that should be my starting point i would think? any suggestions on possible causes or what to test/do next??
