'97 GC has occasional problem where heater blower stays on after key is removed from ignition. Turn signals also work without key at this time too. Even if heater blower is turned off, battery drains to dead in about 8 hrs. pulling 50 amp MUX fuse under hood is only way to stop drain. perhaps bad relay somewhere?? but what circuit and which one?? Thanks

I would look for one of the main relay that control the blower and accessories, it could be sticking on and creating the prolbems. Someone with a chiltons or Hayes manual should beable to tell you witch relay it is. Good luck and hope this helps.
