So i have a civic 92 lx what i put a new compressor and thought that was the problem that didnt work and still blows hot air when ac is on ! I have no leaks . and ac fan turns on what else can the problem be

 

expansion valve? clogged lines? clogged condensor? clogged evap?

 

Is the compressor cycling on and off? If not, does it ever cycle on?

Did you recharge the system yourself after you changed the compressor? Did you pull a vacuum? What was the ambient temperature and what kind of high side pressures were you seeing?

If the compressor was bad, it may have taken out other components. Did you flush the system? Did you replace anything besides the compressor?

A 92 Civic would have had an R12 system - what kind of refrigerant did you recharge with?

 

Without details about why and how job was done, help here is only random guessing.
