   Subject: after run relay                                                        
   well i just fried the 2nd after run relay in not nearly enough miles  ;(        
   first time: i parked the car in the garage, after run came on, i went into the  
   house and returned to a dead battery and a brown relay (it was the short grey   
   one in the main fuse box)                                                       
   today: i parked at a store, after run came on, i went in and returned to hear   
   the fan on (full speed) after it should have been shut off.                     
   once again, the relay was turning into a roasted marshmallow.                   
   i haven't gotten home yet to consult the book of bentley, but i'm going to      
   start by looking for the sensor at the bottom of the upper coolant nozzle       
   on the engine block.  the coolant is seeping from either the threads or         
   the sensor housing itself and probably filling the rubber boot that has         
   a bunch (8?) of wires coming out.                                               
   my radiator fan and fresh air blower are competing to be the first to           
   discover fire.                                                                  
   i'll be looking at it tonight so any ideas for either problem would be          
   appreciated.                                                                    
Make sure you're using a suitable-rated relay. Not all relays are created
equal, even if externally they look like the same configuration. Anything
touching the radiator fan should be 40-Amp rated, at least. Otherwise,
you will be arcing and gradually welding the relay contacts together,
which in turn results in terminal meltdown, just as you're seeing . . .
