Air cond problem

[Slips]

how about the ac is cold but have sound from the vents?
the higher the fan the louder the fan... it's not the air sound, more like rattles and hisses...
tried off ac and no more sound...

hi all...

dont really know how to describe my problem here. mine is 325 m54. centre vent blowing hot air while driver right side vent is some what cold. was noticing this for about 2 weeks ago at night. and next morning air cond working good.

i didnt do any check up. and it keeps happen a few times, centre vent blowing hot air when i left the car idling for about 10 minutes.

and today..it happen again and went to a normal workshop just to topup the refrigerant and no...pressure is not increasing... mech said that it is leaking somewhere...or my compressor went south.

lets just wait for tomorrow morning to see if its working again. just now...when i reach home, switched on the aircond auto mode the blower atuomatically full blast...and i can hear sounds of radiator fan at full speed...again its a hot air..

head ache...head ache...

hope its nothing major...cooling coil/FSU should be fine...but please....please not compressor..

anyone can advise me on this?

dun think is cooling coil or fsu as it can b normal n can b faulty at times.....most probably is ur compressor engage n disengage....sometimes it cant engage could b due to several factor...1 of it is wen u idle...ur alternator is not producing 13v....i had this problem before...wen idle my alternator only giving me 11v...compressor will run intermittent ly....but once is stop working..it wont work thru out the day...or for 1st 15minute...it works....

problem is solved by just refilling refrigerant gas. zzzzz...but hav to bypass heater.

new problem...AUTO mode is not functioning very well for circulation. temperature was set to 26degC and it lows more at leg room rather than centre vent.

been cracking my head on which sensors that i need to look at.

any opinion? ref: http://www.bmwtech.ru/pdf/e46/ST034/8 Climate Control.pdf
