lately i've notice that my fan hasnt been blowing hard, blows harder as my speed increases, and will stop blowing all together when my tranny starts working hard(liike going up hills) i have know idea where to even start with this???

 

sounds like a vacume problem

 

 

I believe that he is trying to point out that with a vacuum leak, the blend door will close and usually the air will all go to the defrost vents. This is a normal problem with a cracked/broken vacuum line and does not sound like an actual issue with the blower motor. Hope that helps

 

maybe somebody can help me i have a 2000 ram 2500 with the 5.9 i tried my ac for the first time and nothing happend the fan was blowing warm air but couldnt hear the compressor kick on any suggestions?

 

actual meant elaborate on where the vacum hose would be... but thats some good info

 

there are vaccuum lines under your dash that actuate the blend doors. They are a PITA to get at. Start looking at the lines under the hood around your master cylinder. with the truck running just spray a little bit of water on the lines and you will be able to see where the water gets taken in.
