I need to know how much freon i need to fill up my a/c, it didnt used to work but after soldering the connections on the climate control it works but blows only hot air, any help would be appecriated

 

i filled mine up after replace the compressor to 45psi, and it works good.

 

Freon? What year of car do you have? Really I have filled up my R34 myself and it wasn't near as good as taking it somewhere and having it flushed/refilled. Just my 2 cents though...

 

well its a 92, but i converted it to r34 about 2 summers ago. The preoblem was that recently i took it to my local honda specialist and i asked him to check for leaks and refill it. he did but he told me my a/c switch was messed up and had to bang on the dash to have the a/c light on, without it wont blow cold air. well after soldering that switch and fixing that problem, i still blow hot air, and think maybe i have a leak or am just out of freon, but that seems to quick to me, it was only about a month ago

 

Damn, you did a conversion! How lame was that?

And if you did the conversion you don't need Freon, you need r134a...
