Popping pas fuse

  1. #1
    My electric window switches, pas and heater blower don't work and keep popping fuses when turned to first click of the ignition key. Ive unplugged the PAS unit now to isolate it from rest of the system however it still does it. Also the heater blower is positioned in the "Off" setting too. The only hint I got that it was doing this is the car was showing its battery warning light yesterday when running however this has no stopped. Does any one have any ideas as to what it might be?

    Check your alternator connections & the main engine earth strap too.

    Checked and all are tight and clean. However the weird thing is the fuse covering the electric windows, pas and heater blows as soon as you put a new one in providing the ignition is on. However, and heres the odd thing, when you rev the car over idle rpm the battery light on the dash comes on yet the PAS and heater blower then start working and stay working until you switch the car off. Only the electric windows seem to be not working however ive tried unplugging both electric window motors and the fuse still pops. Can anyone offer some more advice?
