Hi All.

I have a question for all those that may know. I have recently picked up a second hand tailgate for my A3 primarily for the rear spoiler which is original audi S3 with brake light. After stripping all the parts from it i'm left with a bare bones tailgate with Glass which is also very nicely tinted and way to good to go to waiste. I am thinking of swapping my rear window over but wanted to ask if anybody knew if there was a way to checking with a multimeter whether the heating element for the demister was good before i go ahead with it. Last thing i want is to switch them over only to find it's no good.

Thank you as always. Matt.
