No airflow across the condenser at idle.....

Debris between the codenser & radiator.

Bad fan clutch.

A combination of both.

Check for thrash build up between the condenser and radiator. Jim

Replacing that clutch isn't that big of deal in neither effort nor money, but can end up causing bigger problems if not fixed. My '01 Yukon cluth was not disengaging, and built up so much pressure it blew a line. Worth doing right away.
