Hi All Next job on my car is to find out why the heating and ac doesnt change to differnent vent positions....the heater fan is running fine and blows cold on all speeds but i know i think i am losing vaccumm on the main heater air intake as when the system it is running after a while the flap closes causing a loud squeel :)...i can hear also hear no 'swoosh' noise when i change the mode switch to each position Any advice before i 'waste' my cash on a new mode switch only to find some other problem is causing it ??
