Diagnosing a blower that began ticking and then stopped
Today my blower started making a ticking noise and then stopped completely. Only very slight output when traveling at speed. Didn't stop immediatly but after ticking for ~5 minutes. No noise suggesting fan is rotating. Any ideas? What do I start checking first?

Most engines now use hydraulic lifters and they can leak a little, this causes space between then lifter and the push rod. This results in a tapping noise that goes away when they get warm or fill back up.
OK. The noise you are hearing is the recirculation flap motor. It could be what is causing the condensation. Easy way to check in after the noise has stopped push the recirculation button on the AC controls to see if the noise happens. If the motor is bad and the flap isn't closing you could be getting moisture from the outside air. As far as the check engine light goes there is no relation. 2 completely different systems. The flap motor would probably run you a couple hundred of dollars. The check engine light could be anything.
unfortunately at 140,000 miles much like humans parts start to wear... now you can try to flush the oil system...I DON"T RECOMMEND IT.... I have seen engines tear apart from engine oil flushes.... drain refill the oil/filter with new oil and an additive may help, or pin down the noise to what lifter is going south and have it replaced... may end up being a very expensive repair depending on what they find when they open the engine up with high mileage...or just continue driving it untill it completely wipes out... I do belive its a hydraulic lifter that is not pumping up causing the tick and if so they usually last a long long time noisey.
check blower motor resistor its a little chip thats usually next to the blower motor. the same thing happened to me i bought a $160 motor replaced it and nothing, so i tried the $20 resistor and that did it i wish i would have tried the resistor first but you live you learn.
I kind of had the same problem with my car, the dealer kept saying it was nothing wrong with the vehicle and that the ticking noise would fix itself electronically. Wrong, it was my valves needed adjustment and that ticking noise was never going to be fixed electronically.
