505subie Posted February 22, 2005 Share Posted February 22, 2005 My cabin ac directions (vent, dash, defrost, heat) have defaulted to the dash no matter what control is selected. The blower works fine. I wanted to check with you all first. Could it be..... Satan Fuse Vacuum line popped off under the dash (I suspect this based on below) other ?? I have never had any problems until just yesterday no recent changes. I have noticed in the past that when I would switch from defrost to heat there would be a delay and then a pop as the door in the vent opened and hot air started to blow out by the floor. Please help we are getting awesome late season ski conditions in New Mexico and I really need my defrost back. Quote Link to comment Share on other sites More sharing options...
calebz Posted February 22, 2005 Share Posted February 22, 2005 Could be a vacuum line on the control unit. Could also be the little vacuum canister under the hood. Its on the passenger side right in front of the firewall.. I have seen a couple that have gotten old and cracked. Quote Link to comment Share on other sites More sharing options...
GLCraig Posted February 22, 2005 Share Posted February 22, 2005 I would check to see if you have a disconnected vacuum line. Quote Link to comment Share on other sites More sharing options...
505subie Posted February 22, 2005 Author Share Posted February 22, 2005 I would check to see if you have a disconnected vacuum line. Thanks Craig and Caleb. This is just a new one to me now I know where to start. Hope I don't have to get into the dash. Quote Link to comment Share on other sites More sharing options...

A new one fixed that problem on my car. Quote Link to comment Share on other sites More sharing options...
