1999 GMC SIERRA, heater making making noises in dash
Hello, I have a 99 gmc sierra ext cab and just the other day it started making noises coming from inside the dash and the heat and air temp controller like stopped working. Even with the heating and air switch off truck running you can hear something moving
back and forth it sounds like some door or something. Does anyone have any ideas of how to fix this problem.

Did you find out what was wrong? I had a problem with my Heat/AC that had a similar symptom (noise under the dash), but I'm not sure if it was the same as yours. If you fixed it, you should tell us what you did!!
