AC Stopped
Hi all, I jumped in truck this morning with the ac blowing cold. All of a sudden it stopped blowing at all. It has been acting crazy lately where the fan speed jumps around. If it is on high and I lower it, it would stay for a minute or two then jump back up to full blast then drop back to low. All the fan speeds in between did the same kinds of things. Sometimes it would just stay on full blast no matter what setting you put it on. It is one of those with the digital controller. I verified the ac compressor is coming on and cooling. I can feel a bit of cold air if it is on the fresh air setting. Just nothing from the blower motor. I replaced the blower motor, fan, and resistor not too long ago. I checked all the relays and they tested good. Do you think the resistor might have gone out again? Not sure where to start checking.

Not sure what year your truck is, but this is for a 2007. I don't recall if that system changed through the years, but you can use the info at the top of the page to navigate to the right place for your year. Hopefully, this is helpful:
