Help!!! My freebies eating Fuses!!!

[maffy]

Can anyone help, for some reason my "05 HSE Auto has decided to start eating fuses on both the electric windows (not drivers window) and the radio/sat-nav, this is a pain as you have to re-calibrate and set up the sat-nav every time this happens, this appears to be an intermediate fault as I can go some days with no probs and then all at once? I have pushed in the relays and all the fuses to make sure they are seated firmly but this has no effect, I hope there is a simple answer, whilst the beast is still under warranty i dont have the time to book it in and wait 3 days for the LR dealer to tell me they can find no fault
All answers gratefully recieved.
Cheers.:(

If it is under warranty, get them to sort it out. If you mess you could invalidate it.
Meanwhile, try isolating one circuit at a time.
