slk kompressor 230
Whistle noise from fresh air flap
hey, i have a 2001 slk 230 kompressor amg kit factory, well it seems that lately while at a light, or a/c is off theres a high pitched whistle sound from fresh air vacuum, i removed the glove box and the fresh air door is stuck on outside air, i did a test, and hooked a vacuum line directly to the part that has the diafram, it does pull the door closed, but should you turn off a/c, it starts making a whistle, and i cant seem to remove it inspect futher, can any help me remove the part
