Default Heating/ AC problems????
New to the forum! Just got in my Tahoe and turned the defrost on and nothing happened. Switched to the floor vents and the dash vents still no air moving at all. Looked at other threads, maybe blower, vacuum lines, electronic? Anyone got any suggestions?? 2005 Tahoe Z71 4x4. Thanks in advance!!!

I have a 2003 Silverado and the same thing happened to me. What my problem was the heater control module. That is the part that you change fan speed temperature and all other climate control settings from. It seems to have been a problem with this style vehicle.

ddavis05: Welcome to the forum.
