2017 Trax LTZ
I have replaced the resistor twice now. Each one only lasted about a week before burning out again. The last one actually melted into the wiring harness plug on pins 3/4. Now I will have to order a new harness & resistor. My worry is that even replacing both these, it may burn out again.I just had the same issue with my vehicle a 2018 Trax LT. Did my research on here and went to the local Chevrolet Dealer, bought the new resistor. (No one else had them) I installed it in about 20 minutes with some body contortion and voila! My variable speed fan is working again! Thanks guys for all the help! Shout out to @Traxy for the help! Good solid information. Cost me 31.92 at Chevrolet Parts, plus 6.28 for a 3" ratchet extension. A LOT cheaper than Chevy would have wanted.
Any ideas on why they would keep burning out? The blower motor itself runs fine when the resistor works and I have replaced the cabin filter with a new one. What other causes can I look at when I install the next set?
