Winter made me think about the problem I've actually had since I bought my 5th gen. prelude - side mirrors heating didn't work. I didn't care much at the beginning as I was going to replace the original mirrors with those from the new european accord which in my opinion suit the prelude body much better /somebody interested, I could drop a line/.
Unfortunately, the heating still doesn't work despite the fact the wiring has been checked and everything including the LED indicators /wiring led from the fenders/ works perfectly.
Is there any separate fuse responsible for this or maybe I should check something else?
