I took my car in to the local Lotus dealership for regular maintenance. I explained that the AC has been freezing up lately after 20 to 30 minutes of use (air going warm, volume of air pushing through system decreasing). I know this is a common problem, so that's why I am posting this. The service technician told me they have a repair that can help limit the condensor freeze that causes the problem. I will find out what the repair or fix is specifically when I pick the car up Friday.
