Honda Odyssey A/C Problems

About 6 months ago I bought an '02 Honda Odyssey. A month ago the a/c went out. A friend who is also a mechanic looked at it and said the condensor had to be replaced because of a rock. We did that, but it still didn’t work. Today he picked it up and returned saying that it was fixed - he said he had found these small yellow balls (he showed them to me) in the lines. He removed them and said it should be working now. It’s not. Any ideas on what to do next? Should I take it to an a/c specialist?

Small yellow balls ??? Oh well, is it working OK now? If so I would tend to let it go. If there no longer is a problem, great, if there still is a problem, you should know soon. I would suggest if there still is a problem, seek a real A/C shop (often the do radiators as well.)

Nope, not working. It was barely working when he dropped it off, but it’s not now, a few hours later.
I will seek out a real a/c person. Bummer…already sunk money and time into it…irritating.
Thanks for your info.
