Hey guys, i got a problem....first off my A/C doesnt work. Heater works fine and HOTT but A/C doesnt. When i bought the truck about 4 months ago it actually blew air out from the face ducts, but now it doesnt. I can scroll through all the positions and every one blows through the defroster and the leg ducts, but not the face ducts. Im thinking its an electrical problem but im not too sure. Any help is appreciated!

Have you checked your A/C relays under your hood?

No i havnt, are they those 4 little black boxes on the firewall? If so, how would i check them and what would i be looking for?

Yes, they are the 4 little black boxes. Check to see if they are loose. You want to have a shop do a electrical check on them.
