Default Re: Aircon Problem
Check every single vacuum actuator pipe. You only need a leak in one actuator for the entire vacuum system to fail. Lot's of climate control systems use vacuum actuators.

Wild guess, but if the EGR is engaging as the engine warms up and the actuator is leaking it will remove vacuum 'pressure' from all other systems.
