I lost the high setting on my blower recently so I ordered and replaced the Heater resistor under the glove box. High setting worked for about a day and lost it again. I noticed on the old resistor that the number 1 pin had been burnt. Haven't pulled the new one to see if it was also burnt. Last night I was driving down the road and for a split second the blower quit working and came back on. Any ideas on this guys?
