Because it does have AC probably not. You can check to see if the AC compressor is connected. Where are look for equipment you don't have and was a option or a variation on the V90.AfonsoF1999 wrote: 28 Jan 2019, 16:34 The car does have AC, although it isn't working, maybe this is the culprit?
Just thought of another possability. My 2003 S40 did not come with fog lights. I got some fog lights from the Pick-in-Pull and installed them. The wiring to the fog lights was parked in a holder simulator to the pink one on your V90.
Does your V90 have Fog Lights?
