greneyes Posted October 27, 2008 Report Share Posted October 27, 2008 Having electrical problems on '94 Deville. Loose all dash lights and control lights, and heater runs on full on and can't be turned down. Then after car is turned off, must be leaving a connection open because battery drains to completely dead. Anyone else had this kind of problem? Could it be the electronic conrol box for the dash and if so, do you know where it's located? Thanks. Link to comment Share on other sites More sharing options...
