heated mirror fuse blowing ?

hi guys and girls any help much appreciated

discovery 2 td5 2001

basically when I turn on hrw and mirror heaters the "number 8" 30amp fuse blows straight away...I have the boot door card off at moment as just unsiezing rww and need a new stud welding into spare wheel carrier ,so I have disconnected hrw and inspected wiring but still the fuse blows straight away.

basically my next cunning plan is to remove both front door cards to unplug mirrors to see if this stops fuse blowing.

both mirrors adjust and fold in from switch.

driver side looks original but passenger looks like cheap replacement glass.

so my questions are is my cunning plan pointless,which mirror to start with or any better cunning plan would you recommend to a newbie.

thanks in advance

First up - post in the disco section you will stand a better chance of someone knowing what the f&*k there on about. And ull avoid the **** taking a little

Secondly, sounds like your on the right track. Process of elimination is the way forward.

Disconnect the offending items one by one and go from there. If its not the items then test that section of the wiring for continuity. Its probably shorted itself getting trapped over time going through a gromit or similar.

I dont have a disco so cant tell you how the heated wing mirror and rear screen work, thats why the disco section will be better.

Good luck.

cheers have put it into discovery section
