So I have had no control over the heater for a while. Tonight I checked the vacuum at the 4 way vacuum connector by the brake servo - it felt very weak. So I connected the brake servo to the heater and intake flap only, bypassing the vacuum reservoir and cruise control. Everything in the HVAC now works!

So I have a vacuum leak in the reservoir or cruise control. I know where the reservoir is, but where is the cruise control unit?

Thanks in advance

I would venture a guess that your HVAC is leaking
and this is from one or more of the pods under the console or the inside outside air flap over the CE panel.. go to 928gt.com and on page 2 under tips and links read Wallys HVAC system test guide, Goodluck!

No, it's working fine when I bypass the vacuum reservoir. All the flaps work, everything.

Has anyone else had trouble with a leak in the vacuum reservoir?

Reservoir and vacuum-operated cruise control are both in the left front fender, behind the wheel.
