02 Trailblazer AC

I have a 02 that the ac works grate till I come to a stop then it starts to lose it's cooling. This started all very quickly. I have not checked the freon yet. The motor temp. is at it's normal temp reading.

Make sure the condenser is clear, check the pressures when this occurs, make sure the compressor runs during the event also.

My 03 would not cool at idle. The fan clutch was changed and it works fine. There was a recall on the fan clutch.

If you mean the cooling fan, there is a TSB, not a recall for the fan clutch either locking up, or not cooling at low speeds, not cooling at low speeds can cause high condenser temps which will shut the ac down, these things must be checked for a proper diagnosis.
