My truck started making what I would describe as a wobbling noise on settings 2 and 3 of the blower fan last week. Yesterday I went to leave and started the truck the fan was on 2 and the selector was set to floor, I went to move it to the floor/defrost option and heard what I can only compare to the grind/screech you hear when you try to start a car that's already running, then a pop and it returned to it's normal quiet but slightly wobbly sound.
I am assuming my blower motor is warning me of it's plan to call it quits in the near future. Doesn't look like a big deal at all to change, but my question is - is there any quick/maintenance clean-up type tasks for these or are they just replace when they start issuing warning threats?
I agree with Mark for the most part. If its a relatively easy part to replace, I'd do it. On some other things, heater core comes to mind, I'd try other things first, (flushing heater core, for example).
I disagree with you, it's probably fine and just letting you know it's still working hard and that it loves you I bet in a few days it will go back to normal. R&R is just a way for the guys on this forum to get you to feel like you have to work on the truck to keep it running smoothly and maintained. I say run it into the ground and then start wondering where the hell you went wrong! Also you can blame Ford for bad designs at that point.
EDIT: Also I would swap it out, blower motors are cheap(ish) and the heater core is right there too

This sounds like a problem with the airflow selector door, an additional / different problem to your wobbling fan noise.
I am not a big "fan" of temporary repairs. I would R & R.
Your truck is 15 years old and a few new(er) parts will lead to less headaches. IMHO.
I had about half of my dash/cluster lights extinguished, I pulled it and replaced all of them (if they have not burned out in 200K+ they soon will).
I am positive others will disagree.
Well let's see.....

And he agrees too....
wow!
Thanks for the input guys, am going to swap it out this weekend and give the rest the mechanical involved a look, makes plenty of heat so I think the core is fine - in fact on floor it burn your feet.
Makes sense to me 15 yrs...R&R makes the most sense. Especially with it being so cold.
Right, when a vehicle is that old you will probably need a new one (whatever it is) anyway, soon. As an example; if you suspect a bad fuel pump just put one in before proceeding with the probing.
