Angry AC Replacement

I have a 95 Honda Civic DX. From the day that I brought it, the AC never worked good. In fact, I took the car back to Honda 3 times the first year and they said it is working to spec.

In any case, when the sun is shining, its barely cool. At night or cloudy day, it is cold. I had it leak tested and no leak was found. I overcharge it and it held the charge so that indicate to leaks.

I am thinking about buying a remanufactured AC compressor, expansion valve, and the dryer and replace the ones that came with the car. Do you think it will make a different? What else, beside the car, should I replace to get the AC cold on sunny days?

I'm not sure of how the Honda temp controls are set up but the first thing I would check is the air blend. If outside air is mixing with the cold, when you are set for max or recirculate, it will reduce the cooling capabilities. Could be a vacuum leak, a stuck or bad air door or actuator, or in the instrument panel control mechanism. Since it seems to be okay at night (cooler outside temp / no sun) and not working well during the day ( higher outside temps and sun heating the hood and air intake area) I would carefully check the air mix out before throwing major parts into it.

When did you buy the car?Does it have a sunroof?By the way overcharging an a/c system does not prove is leak free but can damage the compressor.Incorrect charge hi or low can cause your symptoms.

...definately reduces efficiency. how do you know it has the proper charge amount in it now?

first...get the proper charge in it
second...get it pressure tested to see if you damaged the compressor
third...check the air distribution system for the above mentioned issues as well as whether it has a heater control valve that could be letting coolant flow when it's not supposed to.

get the facts...forget about throwing parts at it
