Ok first question blower motor is located under the hood it is on passenger side here is a pic of what you are looking for. Just unplug it and unbolt it and remove it check inside for any debri and then check the motor for noise.
Now on you A/C problem your freon is too low for the a/c clutch to engage so it won't take in any freon so on the first can you put in you will need to take a paper clip and jump the low pressure switch. You do this by unpluging it and then put the paper clip in the connector while the truck is runnig with the a/c set on max, you should hear the a/c compressor engage now you can put in the freon. Now after you put in the first can remove the paper clip and plug it back in and see if the a/c compressor will engage on it own. If not you may have other problems and we will have to test the low and high pressure switches. Here is a pic of the low pressure switch I am refering to and a pic of where it is at also on the passanger side of the truck.
Here is where it is located.
