i have a 98 ford f150 ext. cab 4x4 with 4.6L engine. problem i am having is when you turn on the a/c or heat, it just blows out the same air....not cold and not hot. its about the same air thats outside the truck.

i also noticed that the compressor does not engage and come on.

hopefully this is all connected to a blown fuse or something not soo costly..but i am not sure where to start. where ( if any ) fuses may be located.

could someone lead me in the right direction to get this problem solved?



Thanks in advance,
