did the test, is sucking air from hole inside air filter housing, can i just unplug the yellow shutter solenoid valve electrical connector from the nest because there is a little round tip on the end (dime size) that is also sucking air untill i unplug the yellow connector and kill the current....also it stops the sucking inside the air filter housing,,,,,,when its unplugged,will this affect anything by its being unplugged since the shutter valve apparenty is not working.........pg 262 haynes test
