Ac only works on high

Have you ever changed the cabin filter? Mine was so clogged that it got to the point where it hardly worked at all
 
My 2006 tacoma did the same and its the resistor. Swapped that out then blows great again. Down fall is the resistor tend to go out al ot per reviews i been reading. Im not sure if thats true but i will see if this one goes put again.
 
I had the same problem so I changed out the blower motor resistor and it worked fine for a couple weeks then started doing the same thing...I heard they go out all the time but 2 weeks??? What else could be the problem??

Check for a melted plug. Turns out only the plug was bad on mine but I changed both the plug and resistor.
