RW> Just where do they mount that blower motor relay. I find that the blower   
   RW> motor relay in my Silverado is a little discolored but no melting to   
   RW> speak of. The control switch is on the dash, but the actual relay and   
   RW> motor speed resistor pak is under the dash next to the blower motor. It's   
   RW> in a little vented box (next to the cabin filter housing) which I think   
   RW> helps to keep it cool. Mine is 11 years old and no issues yet.   
      
   It is mounted in a similar location on the Durango.  Not far from the blower   
   motor, up inside the vent area.  Just a few bolts hold it up there.  On the   
   passenger side about a foot away from the blower motor.  Remove two bolts and   
   it comes down.     
      
   My first connector was melted so bad, I couldn't remove it.  I had to cut the   
   wires and re-do everything with wire-nuts.   
      
   The problem with the Durango is the wire harness melts/shorts and fries the   
   blower motor relay.  When that happens, just the high setting doesn't work.   
   Everything else does work.  Happened to me three times, until I replaced the   
   wire harness and blower motor itself.   
      
   There is a case where the blower motor can draw too much power and fry them   
   over and over again.   
      
   RW> Check the amperage load on that motor in each speed range. Too much of a   
   RW> load will create a lot of heat that the relay and resister pak has to   
   RW> handle.   
      
   Yes, that is what causes many of the failures.  The best bet when someone with   
   a Durango has a problem like this, is replace everything.  Wire harness,   
   blower motor resister, and blower motor.
