Having problems with your 2001 Chevrolet Silverado ?

The A/C - heater will only blow through the defrost vent. Please help!!!!

\015 I used the defrost while in the city and it was really cold when I returned to my home town where is is hot the i tried to change it back to the the front and floor control and the air only comes out of the defrost. Today I pulled the dash and and cleaned the filters and the air comes out a lot better, but still only out of the defrost! Thanks for your time, hope someone can help!\015 Posted / edited by AnonymousUser on : 19-03-2018

Answers :

While you had the dash apart, you should have checked the blend door.
The defrost mode is the default position if anything goes wrong with the system.
The blend door could be stuck, or the motor may have failed. Could also be a problem with the control on the dash.
