1991 Honda Prelude. The electric vent selector broke recently so it only blows from the defroster. I don't know how to fix that or where the unit would be to replace.

Wait there's more.

The A/C doesn't blow cold. It blows slightly cooler than what's outside. Like .01 degrees cooler. It might just be in my head. How do I make it cold? It's got an R12 port (I think). The R134a port is a lot bigger than mine. Mine is small. But enough about my *****, the valve on the cold pipe (or what I think is the cold pipe) is smaller than the sleeve cap on the R134a can. The other pipe has a valve equally as small. Can I charge it? And how? And how do I fix the vent selector?

 

you can charge it. id personally take it somewhere to have it done. its cheap to do. youll have to buy the old freon. i believe could be wrong.

the electric problem is behind the dash. the unit itself is probably the problem. just undo the front and pull it out like a cd player.

 

Ok thanks!
