Hi there, to cut a long story short I have a 2005 skoda fabia vrs now I have never had any electrical issues since I have owned the car (over 4 years) but now I have really random electrical issues the electric windows, front and rear fog lights, electric mirrors, air con, heater blower now no longer work has anyone else experienced similar issues? I was thinking a relay or earth I have checked all the fuses and earth straps and everything looks good anyone got any other suggestions 

Many thanks 

Just thought I would add heated mirrors are working fine and the lock/unlock button on the door with window switches work fine and can put windows up/down with key in the door.Everything come back on for about a minute earlier while idling but then went back off please help driving me mad 🤬 I have just spent a load of money on pd150 turbo new aluminium rad remap now this!!

Measure the voltage between the battery posts, before and after starting the engine.

Hi Wino, thanks for reply I will try this later on will borrow volt meter from a mate then post back what I find
