ac problem

[mario_da9]

hey guys i fixed the ac belt on my car after it broke a couple months ago when replacing the alternator, but it only blows hot air out the vents. Few problems too, the switch to switch from cold to hot is somewhat broken and my freon is completely empty,

help

well lets start with filling your r134 .
the switch from hot to cold is sometimes cable controlled so look to see if that's loose.
