Default Re: Air Con mystery

Most modern climate control systems will not blow air into the cabin when first started. Instead, they will circulate the air within the system until it achieves the desired temperature before opening the vent into the cabin. Could this be part of your issue Sean?
The ML is a manual system and just blows air at whatever temperature until it cools (as Michel reports; in less than a minute). All my aircon systems run at about 7 C output at the main vent. Have you checked the temperature of the air at output Sean?
Regards,
Brian
