So this is for my '00 F-250 Powerstroke. It blows cold, then it'll blow warmish air, then back to cold, but in no particular pattern...any help?

if it has a vaccuum regulator behind the dash, this controls the a/c, check the hoses going to it.
check and see if the compressor is kicking on and off at the same rate as the warm/cold issue. You could be low on refridgerant, and the low pressure switch is kicking off...
being a 2000 it should be 134a refridgerant. you can buy that stuff at walmart. add a half can and see what happens. DO NOT breathe the stuff, it causes testicular cancer. (not a joke)

And a guy from "thedieselstop.com" said not to add freon/refridgerant because too much could cause problems too, i had never heard of that.
