My 2006 Jetta 1.9L 5MT 210k miles, makes a rattle sound when its cold and the blower motor fan speed switch is on. I can make the noise start and stop by simply turning the HVAC system on and off, and it goes away when slightly increasing RPM. It is only an issue before it reaches normal operating temperatures and gets quieter as it warms up. Any ideas?
