I have a 92 Prelude and I was driving home and the AC stopped blowing cold air
I just had in the shop for the ac not working and the replaced the ac pressure switch and the ac compressor relief valve because it blew all the freon out and that is what it did again
What could be making it build so much pressure

 

clogged orifice tube? although they should have replaced that anyways, since it is a 5 dollar part.

 

Is the orifice tube easy to clean out,something I can do
Where can you buy this.
