2003 F-350 blower motor questions

When I turn on the A/C there is a loud noise and a strange smell coming from the passenger side under the dash is the blower motor gone ? If so where is it and how hard is it to replace? Any and all help would be appreciated. Thank you for your time.

What's the noise sound like? Is it possible a mouse got in your A/C system? That will cause a strange smell for sure, and isn't an unusual problem.

Its a loud humming noise, someone told me it might be the bearing went out in the blower its a loud rattling and humming. The smell almost smells like freon. The floor of the truck is not wet inside, so I don't think its the heater core, I think that's the part behind the glove box that look like a little radiator.

I had an explorer that the bearing went out in. At low fan speeds you didn't notice a thing but at higher speeds it would vibrate the whole dash and sounded like a heard of elephants running through the vents. If you smell antifreeze I'd bet your heater core is heading south. That's a pretty big sign of it even if it doesn't get the floor wet.

The smell only occurs when the the blower is trying to work and it only started having this smell since the blower motor problem. A couple days.

Blower motor takes about an hour to replace. It's not hard and it's all under hood.

***Problem resolved*** Takes about 10 min. to replace under hood back left side 3 bolts and out it comes. Noise was from the cage where the nut that holds the cage on had a crack right under it so the cage wobbles when it turns causing the noise. Thanks for everyone's help.

Cool you got it fixed. I was going to say about a 10-15 minute job but I got jumped on awhile back for saying I did a hub bearing in an hour so I shot overboard.
