[Vwdiesel] Re: vacuum assisted heater controls

[Mark Laplante]

I had the vacuum booster rebuilt shortly after acquiring the car back in April; maybe they did not reconnect the vacuum line for the heater controls. I will look and see if I can see where to connect it. If there is a T that is open to the atmosphere (due to HVAC line being disconnected), wouldn't my brakes be affected?

(I had the booster rebuilt because I would get only one good power assist. Creeping up behind traffic going slowly through an intersection would result in rock hard brakes on about the third application.)

Thanks for the help,

Mark
