Doc Posted February 9, 2010 Report Share Posted February 9, 2010 I have got a 93 cutty vert and has the scc hvac unit. The rear defost light comes on but no action on the window. Check connections @ the window and they looked good. Any ideas?????? Quote Link to comment Share on other sites More sharing options...
slick Posted February 10, 2010 Report Share Posted February 10, 2010 Fuse/Relay? Try measuring voltage at the connector at the window? Quote Link to comment Share on other sites More sharing options...
jeremy Posted February 18, 2010 Report Share Posted February 18, 2010 I was gonna suggest the same thing as Chris....check the voltage at the defroster itself when the button is turned on... Quote Link to comment Share on other sites More sharing options...
