04 Grand Prix GT Started this morning on the way to work. It's no pooring out but after a 45 minute drive I had a 2-3 puddle on my floor mat. Upon further inspection this afternoon it seems to be coming from the inner left side of the passenger area next to the middle console piece. Our best guess is the heater coil? Can anyone steer us in the right direction and if it is the coil how hard is that to get too and fix or is it one of those better off taking it to the shop issues. Thanks in advance guys.
