Default How to fix my 99 Civic a/c?

My car cools effectively at night r temperatures below 75 degrees. On hot days like today (95) you can feel cooling, but it's NOT enough to cool the car down. My refrigerant is not leaking and full. I replaced my compressor that had gone out and condenser... But not my receiver/drier. Could this fix the problem? Or does it sound like an expansion valve?

OK I hate to tell you but the a/c 96 thru 2000 Honda civic was not the best but there are some basic checks you need to make. First thing there are 2 hoses coming off the compressor with the a/c on and the engine between 900 to 1000 rpms. MAKE SURE YOUR RPMS DO NOT GO OVER 1000 RPMS FOR SOME REASON THE A/C COMPRESSOR TUENS OFF AT 1100 RPMS AND YOU WILL NOT BE ABLE TO DO BASIC CHECKS IF A/C COMPRESSOR IS OFF. With the Rpms between 900 and 1000 and the a/c on Max a/c with a/c blower to full speed place a thermometer in the center vent and wait about 10 to 15 minutes and check the a temperature. The temperature should be around 45 degrees. With the AC gauges installed the high side pressure should be around 225psi with the needle bouncing this is normal. In most cases a bouncing needle means that the compressor that is bad but is normal on this car. The low side gauge will be about 35 to 45 psi. If all the number look good then that's the best that car can do...this is a standard test that we use at Honda and it is referred to as an AC performance test. Make sure all the window on the car are closed and the car in in the shade. If you have no gauges you can do the setup the same but instead of gauges your going to touch the AC hose that goes form compressor to condenser. BE CAREFUL IF THE AC IS WORKING PROPERLY THAT HOSE WILL BE HOT...NOT HOT ENOUGH TO BURN YOU BUT HOT ENOUGH TO GET YOUR ATTENTION. If the hoes is hot check the other hose that is right next to the high side hose if it is cold to the touch then the AC is normal...not much you can do...good luck

The gauge readings with R134a are not nearly as instructive as they were with R12 because the system will get into a variety of states depending on how long the A/C has been running, how much air flow there is through the condenser, the engine rpm, and the charge status. It is a remarkably bad sign that the compressor had to be replaced - except for systems somebody tried to charge at home the compressor should last at least 15 years.































The receiver/drier must be replaced whenever a compressor has failed because it is not uncommon for debris from the compressor to collect in there. Rather than continuing to throw darts at the problem (in truth, that is all I can do on an R134a system which is why I don't mess with them) it is time to take it to an A/C professional. You would be amazed how much cheaper it is to get the system going that way.

First you should touch the receiving inlet A/C pipe if u feel ice on pipe its mean Gas is over charge in your A/C unit.Second check your thermostat is working well?third you check your expansion valve.
