Air conditioner woes
 

Our air conditioner started making noises a couple of days ago. Yesterday it quit blowing air at all but would suddenly start bowing again. Today no air at all. In researching the issue I came across a couple different posible causes: blower motor resistor or blower motor. Do either of these sound right?

Year of the truck?
manual ac or auto temp control?
I assume you are talking about the blower not working?
The blower started making noises? what kind of noises?

2004 F150 manual ac....yep blower not working. Sounded like a hard rattle or like a card stuck in bicycle spokes. Got worse the higher the fan was turned on.

Sounds like a new blower or blower motor is the ticket. The resistor wouldn't cause it to make noise.

Ok thanks. That's what I was thinking.

When the resistor goes, the fan works in highest speed only and should not make any unusual noises.

That sounds like leaves or something got into the fan.

Haven't really worked on vehicles that much but the YouTube video to replacing the fan motor looks pretty straightforward. Is this something I should take to a mechanic or would I be safe to try and replace myself?

DIY. It's about the simplest repair that you can do.
