Hi guys.

My EF fairmont has constant vacuum coming from the climate control vent. Changed 3 units, still having vacuum sound. Only goes away when i goose the throttle.

Is it normal? Or should i do some problem solving...if so how?

hi all are there any replies/possible input?

Wow this forum is dead and useless

The forum has slowed down in activity in recent times. Old timers have moved on and have other responsibilities and finding spare time to reply on forums is not a priority. Be patient and someone will reply, unless you are in immediate answer, best to call/ask a mechanic...they may give answers much quicker.



What did you mean by CC vent? The little slit at the bottom of the CC unit? Or are you talking about vacuum noise in general? If it's the latter, check the vacuum box behind the glove box and trace where the vacuum is coming from. You may simply have a loose vacuum hose or one of the vacuum actuators is busted leaking vacuum.

In either case, where exactly is this vacuum noise coming from?
