I have a 2003 Grand Prix SE with the 3100, about 2 months ago I've had the engine replaced since the first 3.1 died back in 2012. It's been running good as new and I haven't any issues on how its performed. Recently I was doing some cleaning under the hood and saw this
Ive looked at Diagrams and looked at other posts but I cant seem to find where its supposed to go. My mom has a 2004 3.5 Malibu and hers just has a plug. Only problem with the car as of now is that the A/C only blows to the floor and not the normal vents. Some sites have said it might be a Vacuum Leak. Blower and Blower Motor resistor are new and work well, anyone know what this is supposed to be connected to? and if this is related to the A/C issue?
