Report Relay window voltage module C082M6531F required in Interior/Exterior/Lights/Glass/Electrical/Alarms/ICE Posted March 29, 2016 Help, just blew up the window relay. can't find a new window voltage module anywere pn. C082M6531F, everywhere obsolete. Also I have being looking for a alternative but don't know where else used. And as it is obsolete I think it might be Esprit specific. Only brand reference is BMI moulded in the plastic. Any thoughts.
