On my ED Ghia above the clock and next to the rear demister switch is the opening that houses the cabin temp sensor. After driving the car for ages I can hear a sort of sucking noise or whistling coming from it. I have checked all the vacuum connections etc and they seem to be fine. anyone else had this??? Its drving me insane cause you can actually hear it over the stereo when its really bad...

I had this in my EL Fairmont... also noticed that it stopped when accelerating. I put it down to vacuum but car was written off before I found the time to check this.

Peuty

is that what that mini grille is?

i believe that the temp sensor is hooked up to the HVAC system in such a way that air is drawn from the cabin, through the sensor and into the heater case - if you remove the sensor you should be able to look down that tube (or remove it) and see if there is anything in there that may cause the air to make a noise as it is sucked down the tube - also look at the actual sensor for any restrictions.

thats providing it works like most other climate control units work...

The cabin temperature sensor is mounted in that grille. This is used by the Climate Control to control the interior temperature.
Mounted further in the dash, behind the trip computer, is a small electric motor and fan assembly and this has a flexible "accordian" tube to the sensor. This fan draws the air through the grill and over the sensor.
The fan and moter run constantly when the Climate Control is on.

There may be a problem with the fan unit (e.g. bearings in the motor).
