One day my AC didn't blow any more cold air so I refilled it and itit worked fine for a couples of day. Now there is no cold air and my vents are stuck on defroster. It wont blow anywhere else. Can someone please help?
Sounds like the clip that anchors the temperature choice cable has loosened or broke. Check down under the right side of the dash to see if the cable moves when twisting the knob. It should not move.
Check the vacuum line that feeds the HVAC control panel. In the engine compartment near the top of the firewall are some vacuum hose(s) and connection(s). Check for spit connector(s), hose(s), unplugged lines.
Check the vacuum line where it connects to the back of the HVAC controll panel.
