Okay, my air conditioner motor blower fan stopped in the front. I have changed the resisted or whatever it is called located under the passenger dash, several times it will work for a day or so and then it goes out, so there is a short somewhere because when replacing the part I notice a prong will be burnt but it is a different one every time. Can you help me?

Check the blower relay under hood fuse box then do what I have sent in picture and check to see if resistance at control it may be the switch has been burnt up or harness there as well as at resistor. If everything checks out okay then use dielectric grease on resistor also do check from resistor to blower as it may be drawing to many amps.
