ystrdyisgone Posted February 18, 2014 Share Posted February 18, 2014 About a week ago, during our most recent deep freeze, my heat selector switches stopped working. (Defrost, Vent, Floor, etc..) From my reading around the board, I gathered that it's a vacuum issue. An issue presented itself to me right when I opened the hood: This is the vacuum canister right? Goes from the engine, across the firewall then down into the cab from there. So I'm confused because my selector switches have worked since I've owned the car, but this loose hose appears to just be sitting there, there is no other hose coming from the intake that mates up to it. Or even a bare vacuum port on the intake, they're all plugged. So I guess the question is, is this my problem? Thanks! Link to comment Share on other sites More sharing options...
presslab Posted February 18, 2014 Share Posted February 18, 2014 Yes that canister is used for the HVAC pushbutton controls. Link to comment Share on other sites More sharing options...
ystrdyisgone Posted February 18, 2014 Author Share Posted February 18, 2014 Just found the other end hanging loose behind the engine, it was hiding a bit. Today I learned even more, to investigate further on the car, and on the site, before posting. This thread can be deleted. Link to comment Share on other sites More sharing options...
suprjohn Posted February 18, 2014 Share Posted February 18, 2014 Might check the plastic line across the firewall if this doesn't fix it. Mine had a pretty bad abrasion in it. John Link to comment Share on other sites More sharing options...
