Hello. Is it normal that my mirror heating wires (two wires which come to back of the heating element) give static 7.3v reading when heating is off? I tested the resistance of the heating element and it gave around 10-20ohms which should be good, right? Haven't been able to test if it puts over 14volts when heating is turned on, or is there a way to test that without vcds? So I have octavia Mk2 year 2006 pre-facelift elegance.

Would love to get this working before next winter

I have problem with passenger side mirror heating. The problem is that there is all the time battery voltage even when switch is off and ignition key away. And that have probably caused mirror heating to fail, mirror heating wire is burned through. I checked also driver side and this is working fine. Voltage will apply only when engine running and switch is turned to heating mode as it should be. Drivers side heating wire resistance is 5 ohm and passengers side infinite as it should be because continuous power has burned it. Question is where this power is applied to mirrors from cause to drivers side is ok but to passengers side not. Is there relay or something that supply separately positive wires to mirrors that one contact is burned together? Or is there some block somewhere which is controlled by switch and this block is faulty causing continuous power in any case to passenger side mirror heating?
