rktec Posted December 13, 2018 Share Posted December 13, 2018 My 2005 SC430 blows cold air out the side vent with the a/c off. Any suggestions how to stop? Quote Link to comment Share on other sites More sharing options...
Lexus Owners Club Posted December 13, 2018 Share Posted December 13, 2018 Sounds like the diverter flap isn't working .... maybe keep cycling it to blow in different directions and see if it starts to work, if not then it could be a disassembly job to fix Quote Link to comment Share on other sites More sharing options...
