How to check for shorted blower wiring?

blower motor. Ever smell a faint electrical burning smell?

I have the same blower problem in my A6... how would I check for this fault? I'm getting an intermittent V2 code. Thanks!

I replaced it and the problem got worse, not better. That's why imI wondering if it's the harness. The old blower didn't have much dust inside and i wondwrewif the previous owner replaced it and gave up.
