Honda Car Forum

I have a Honda Civic EX 1995. I live in Austin, TX and my car a/c works fine in the morning when its not that hot, but takes very long to cool in the afternoon/evening. In addition, the engine makes knocking sounds while idling with the A/C on. The mechanic told me that this was due to a condenser problem--and gave me a $400 quote! My question is if the condenser is bad, would the A/C cool at all?Ironhand,Thanks for the response, I'll check for the things you said, but meanwhile Iooks like have another problem! I drove home fie today, no idling at all, but when I got to my driveway, the engine died on me! I tried to start it and it starts up for a second and then dies. Its doing this off and on, sometimes it starts fine, other time, it starts and dies! I am thinking its a loose connection in some electrical part, any ideas?

Not for long.The ONLY purpose for the condenser is to exchange heat, and therefore transport refrigerant. No moving parts. If it fails, it won't retain its refrigerant. If the refrigerant is low, the compressor could conceivably rattle or knock, but in that event the low pressure switch should turn off the compressor.Have you had a front-end collision? Have you struck a parking curb too hard?It is difficult to tell if the condenser is damaged without a good inspection.Look at it VERY CLOSELY and see if it has any "wet" spots or areas where it appears oily. This is a clear indication of a leaky condenser.
