A/C problems with blower and position selector
\015 I have a 2004 Trailblazer, the A/C fan only works in 1,2 or 3 position, also only blow from defrost or feet position no matter where the selector is positioned\015
Sounds like it is vacume operated check to see if all vacume hoses are connected to the control switches and vent controls. i suspect somebody has caused a hose to disconnect tampering under the dash
