grog11... You are awesome. Thanks a ton!
So, olopezm if you have the center control panel torn apart, the black tube should have suction with the car running.
Turn on the fan to the second or third setting. Leave the red "power plug" attached to the A/C heat selector. Turn that one to MAX.
Feel for suction at the Black tube with the vacuum harness disconnected from the control switch.
IF you have suction in the passenger compartment, then it's the switch. IF there is no suction, then the problem is under the hood.
