I set the A/C as cold as possiable and on max A/C or Normal A/C and still just hot Air. All other gauges in the truck are normal, was told there is some sort of flap under the dash that may be stuck and not allowing it to open??????

you need the gauge pressure to diag if its a system issue or a door issue

Mode selector! Feel the pipe(not hose) going inside the truck from the filter/drier. Is it cold? If so then you have a mode selector problem inside the dash!!
