Guest pelagic30 Posted July 28, 2003 Share Posted July 28, 2003 I thought this problem would be more common, since I have two legacy's and they both have the same problem, but I did a search and found nothing. Anyone else have a problem with their air system buttons not working ? I assume that they are vacuum controlled and either worn out or dirty mechanisms, has anyone fixed these ? What did it take to fix ? Thanks, Quote Link to comment Share on other sites More sharing options...
Guest Legacy777 Posted July 28, 2003 Share Posted July 28, 2003 what do you mean buttons stick. Are the buttons physically sticking, or is nothing happening/changing when you press the buttons? It is a common thing on some higher mileage first gen legacies. Mine does it sporadically. A button pushing dance will usually fix it for a while. The vents are operated by a motor. whether that motor supplies vacuum or uses electric.....I'm not 100% sure. I've been meaning to get under there and see what's going on. I believe it's an electrical issue, but not sure exactly what or where. Quote Link to comment Share on other sites More sharing options...
Guest 97svx Posted July 28, 2003 Share Posted July 28, 2003 My 95 Legacy had sticky buttons from coffee being spilled on them. Pushing one button in would not cause the previous button from popping out. Had to take the assembly out, washed it out with water, replaced the illumination bulbs, and it worked fine after that.

Guest Setright Posted July 28, 2003 Share Posted July 28, 2003 My 1990 does not use vacuum. There is a mechanical arm that is moved by a motor. Taking off/out the glovebox should give you access to it. Quote Link to comment Share on other sites More sharing options...
Guest GBianchi Posted July 28, 2003 Share Posted July 28, 2003 The control is electric, mine stops working at times and a good thump on the dash gets to respond, not a technical fix but it works:p Quote Link to comment Share on other sites More sharing options...
Guest pelagic30 Posted July 29, 2003 Share Posted July 29, 2003 I like that fix... thump on the dash. Thanks for the advice. The twins will be easier to live with if this is fixed. 90 Legacy L 2WD 90 Legacy L AWD Quote Link to comment Share on other sites More sharing options...
Guest EOppegaard Posted July 29, 2003 Share Posted July 29, 2003 I had this problem on my 93 wagon, I ended up spraying electrical contact cleaner in-between all of the buttons, and then just worked it in by hitting all the buttons. However the thud may work just as good :-) Quote Link to comment Share on other sites More sharing options...
