Whispering Noise By Glove Box?

[Ogben Schmutzel]

Hi All,

 

You know the noise that a CD player makes when it is searching for a track? I am getting a noise like that from somewhere under the dash but it's continuous

The large box containing the fan, aircon evaporator and heater unit is located behind the glove box. This has a number of motorised flaps. Maybe its one of these thats making the noise, or maybe its a leaking seal that blowing/whistling occassionaly.

Sensor fan in the CC panel? air leak as Sk suggests? try altering the air flow to the different vents and see if that helps?

Ok ta.

Just discovered that if I put the Climate Control on Econ the noise stops.

Does this help with what might be up?

Cheers.

Oggy.

Yes, the "whispering" noise is probably the hissing sound made by the refrigerant in the evaporator when the gas pressure is low - like a kettle - varying a little in intensity and affected by going round corners, accelerating/braking etc. In that case you got a leak and need a topup!

SeatKid,

 

Thanks for the reply.

 

This all starts to come together!!

 

I had the aircon regassed a couple of months ago. Afterwards with the fan on half speed and the Climate on

Getting it checked tommrow, am I bothered :D :D :lol:

 

What with the aircon not working properly and the aux heater non functional either the cars in a bit of a state.

 

Its all my fault - I'm sure I said in a survey here that I had not had any problems with the aircon. :D

 

Will post back with the results - good or bad!!

 

Can there be a good?? :D

 

Cheers.

Oggy.

I too had the hissing noise you described coming from the glove box area.

 

Although I regassed the system it lost all its pressure within 24hrs. Went along to the dealers who found a leak on the condensor.

 

Replaced and regassed. Condensor + Labour =

Umm, jury

Is it possible to lose gas for unknown reason and every thing be ok??

The gas does seep out over time, but longer than a couple of months. Often they also put in seal conditioner and the PAG oil makes the seals swell slightly too, the oil is carried round by the gas.
