SteveWas Posted December 3, 2008 Share Posted December 3, 2008 Hello: 1999 Lexus GS400. The cabin air damper doesn't seem to work. Fan runs fine, air is warm, it will blow air from dash vents when set to that outlet, but won't blow air on defrost or floor from those vents. The dash vents do stop movnig air when set to defrost or air, so there is some redirection of air. Is this electronic, a damper, linkage? Is it a big cost item or anything I could look at myself first? Any help or ideas woudl be appreciatd. Thanks. SW Quote Link to comment Share on other sites More sharing options...

SW welcome to the club.....sound like u have the MODE servo out....mine did that also as my temp servo went out! try searching next time please, it will help immensely. i will post some links to get you on your way though...fairly cheap i think the part is like 150 or so.....plus labor if u paying someone....they under the glovebox so no need to remove all of dash http://us.lexusownersclub.com/forums/index...showtopic=53289 http://us.lexusownersclub.com/forums/index...hl=servo+motors http://us.lexusownersclub.com/forums/index...hl=servo+motors http://us.lexusownersclub.com/forums/index...hl=servo+motors if your gonna do this yourself (its fairly easy....and i swear one of these days im gonna finish my DIY) make sure u get new ones....if u gonna have a shop or a dealer do this, i recommend doing both the mode/temp servo so 20 days later the other one doesnt happen to go out and you gotta pay for this AGAIN.
