98 C-230 climate control whistles while it works
My 98 C-230 has just developed an annoying and intermittent whistling or whining sound whenever I start up the car. It is coming from the climate control system and lasts up to a half-hour before gradually stopping. By cycling through the air flow options, it will only stop when the airflow is directed just to the windshield. Any ideas?
