A/Cissue 3rd post Am I in the wrong forum?
Common problem with the a/c defaulting to defrost. Looked for vacuum leaks and installed check valve. My blend door works eveytime and so does my cruise control. So I do not think it is vacuum related. The A/C works every time on defrost and defrost/floor. HOWEVER Sometimes the a/c works on the dash vents and sometimes it will not. Blend door seems to work every time. TONIGHT I noticed that while the a/c was on and the knob set to the dash vents the a/c light was dimmer then when I changed the knob to defrost/feet. The light will get brighter and then dim, brighter then dim. WHAT THE WHAT!!! Short maybe, bad connection somewhere? Any suggestions. It is the manual control single zone heater/ AC. The cruise works fine so I am doubting it is a vacuum issue.
