I HAVE A 1993 HONDA CIVIC DX 4DR AND MY AC IS BLOWING ONLY COOL AIR NOT ICE COLD LIKE IT USE TO. SO I THINK I NEED A REFRIGERANT. WHAT TYPE OF REFRIGERANT DO I USE?

 

R134a.

I would take it to a shop though, if ur low on refrigerant, it had to go somehwere, it didnt just dissappear. and a leak doesnt get fixed by adding more. Otherwise it could be something like a clogged evaporator or condensor, restricted orifice tube, restricted reciever/dryer/accumulator. unless u know what ur doing, take it to a quality shop...
