On my 2005 9-3 CV that left most vent defrosts the driver side window and I direct the right side vent toward the passenger window to defrost.Starting up in cool/cold weather, 5º C or lower. I get a cold draft out of the leftmost dash vent (LHD car). Presumably ACC is in defrost mode with a cold engine. Is this just a way to defrost the side window?
I don't know if the CV nature of the car works against it, but ACC on my 2004 9-3 is nowhere as unobtrusive as the one on my 2003 9-5. It also takes more fiddling with the temperature than on the 9-5. The same temp is pretty much always the same comfort level on the 9-5, while on the 9-3, it can be too much like Goldilocks and the three bowls of porridge.
which wire was negative and which was positive..Ended up clipping the connector and going with crimp on audio-rated spades.
Looks like Amazon has a GM connector adaptor however, that should work for the 3.5" Infinity's I just ordered.
Will update tomorrow if its the right one. Only $7..
