Question about 1999 Chevrolet Silverado 1500
On a 2004 Silverado 1500 4x4 the air only flows out of the defrost and foot area simulataneously, regardless of the position of the distribution knob on the climate control panel. The blower works fine in all positions. Is there a simple way to check the mode door motor or the control panel wwithout a class 2 scan tool? Where is the mode door motor located?
If it is a ATC automatic control temperature , you will have to find the code. if it is vacuum controlled you will have to check the vacuum hoses that control the mode door. maybe something fell into the defrost vents and it got stuck. the only solution for that is to try fishing out the object through the vents..
