Hi I have a 06' dodge durango and just recently i noticed the fan would go in and out, this happened for about a week until it finally did nothing. I found this sight and others that had alot of info on the blower motor resistor. I took it apart and noticed it was fried on the #1 pin. The harness connecter was also a little melted but i figured it would be ok. I went and got the $10 part at my dealership, put it in and it worked great!!! for about 3 hours. I took it apart again and noticed the first pin was fried again and the harness plug got melted a little more. I did some further checking and found some people saying that the blower motor could be the culprit for this. I went to the local wrecking yard and got a blower motor for $40 with year warrenty. I installed the motor went back to the dealership not even a couple days later now the part was $12 he said something about them changing the serial numbers on them all the time. Anyway i plugged the new resistor in but before i screwed it into place i just wanted to see if it would work. I turned the key to run and switched the fan on it worked fine but i noticed it stayed cool on high but on all the other settings it would get scolding hot to the touch really fast. now i know the resistor is probably suppose to get pretty hot, but i was just wondering if this is the way it is suppose to be. Then i had to go on a trip and out of fear of frying it again i just kept it on high and would shut it off and turn it on high to stay comfortable. I would appreciate it if anybody could set me in the right for what to do next.

 

I am having the same issue...did you ever get prices from dealers on this? i have pin one fried on both ends, just wandering if i should just replace the blower motor and resistor?

 

im not 100% sure how the resistor is installed on your truck, but if it is installed into the air duct, that is done intentionally, to provide cooling airflow for the resistor because of the way it works, it needs to dissipate the extra energy that the fan is not using on a given setting, it does this by turning the electricity into heat.

 

ya paid4 that's what i thought to, now im just scared to try the other setting thinking i'll fry another resistor
