Gen III HVAC Blower Motor?

Just turned on the A/C and got nothing, but a burning smell. Pulled the motor and resistor (not the first time this has happened), and the resistor is fine, but the motor is toast. Last time this happened, the resistor was blown and not the motor, but I replaced them both since I was in there and the motor had a bunch of rust stains on it. Same rust in the motor this time, except this time it actually killed the motor. It smelled burnt, but I put a power source directly to it after I pulled it out of the car and got absolutely nothing.

Are these parts a known issue for these cars? I know there were quite a few threads on the other site about it when I changed them last time, but just curious if anyone has had these go out like this. Granted, it's been a few years and 20k miles since the last time, but I've never changed one in any other car I've owned. Also, since I've never taken one out of another car, I have no idea if the rust in the motor is a "normal" thing or not. The flex tube connected to the motor looks like where moisture is coming from and it leads right into the bottom of the motor. Maybe it's to let condensation evaporate up and out of the blower motor, but after letting the car sit for so long from the end of summer until now, the moisture settled into the lowest point (the motor) and when I turned it on for the first time yesterday, it just gave up?

Like I said, I've been here before, so changing it out isn't a problem. Just wondering if others have this same issue?

Some water does get on the blower motor from the a/c system. I pull the rubber hose off the side of the motor and put a couple of drops of motor oil inside the housing to lube the lower bearing (inside the blower motor) All gen 3 and 4 cars will show rust stains inside the motor if the ac is used a lot.

Good idea. I’ll do it soon, but I’m not in any hurry to be upside down with my feet out of the roof and head under the dash again just yet. lol
