I'm right on the fence here. Will the mounting holes line up with the ones for factory vent?
FWC's are all pre-wired for these fans, right?
Doubt the mounting holes will line up. That is why I went with a Fantastic Fan, I was able to just replace the guts of the vent, and leave the seal alone.
Best I know your 03 is prewired for a fan. It is easy to take off the inside trim of the vent and check for the wires.
