E46 aircond lost coolness

[azeL_Inc]

Hi all!Now i ve got problem with my aircond! I dont normally switched off my aircond. So whenever i switch off my car's engine, aircond will be off, and whenever i turn the key to on position, the aircond will turned on. (so basically i never switch off aircond). Is it bad for the aircond system/battery/etc?The problem i m having now is aircond has lost "coolness". It happened once before, but after i restart the engine, the aircond became normal, cool again. But juz now the problem reccurs. Both day the problem occured,the common thing is i parked my car under hot sun.Anyone know what's the problem might be? I dont know whether the aircond will become cool again or not... zz Add:let the car off for 15mins, turn on the engine and aircond, aircond became normal..so these happen twice. Is it normal bcoz i parked under hot sun? or i am getting into trouble with my aircond? any early advices on what should i do

send it for service...they will check gas & compressor oil level and normalize them (add la). Good workshop will have the temp gauge to check if the air is cool again after the service/refill. They'll stick it in the vent and match the temp reading on your OBC display

gud luck!

cooling coil dirty, that's my case. no need switch off A/C when start car, its a BMW. go check with naidu in jalan gasing behind kwsp federal highway, he's the BMW A/C expert (alot of our member and forumer go there)

shaifulo: thanks for the advice. but will it do more damage if i delay the repair/checking..hehe..outstation!

mouse: will do, so does that means the coil can be cleaned or need replacement..hehe..no idea of how it works.
and about switching off the aircond, i also think the same coz if not, they will make a switch to turn off the a/c, instead of having to press the fan volume lower and lower till it off.

alot of reason for loss of coolness, but if your cooling coil kaput, its a big project and expect a full day repair in naidu's place because your whole dashboard will be removed.

It could be a simple problem with the mechanical knob selection. there is a mechanical knob that allow you to select the amount of cold air from "." to ".." to "..." and "... " being the highest coolness.

Thanks for the info,

the fan is basically working fine, just that driver side is blowing out air only and passenger side is cold.

Ermm, i adjusted the side knob to max blow out....as for the middle one, i adjusted to 3 blue dot.

Wondering how to adjust both to blow out cool air?

im having the same problem , my center went is blowing hot-cond not ac but my both side vent is fine! i check mechanical knob is in max coolnest? wat cud ne the problem? pls help

could be a sign that the heater valve is konked. But better go with the cheaper solution first, which is to check the aircond gas. Out of gas or a leak or a clogged system. Then go and check the electronics, temp sensors and stuff.

Extract from BMW WDS..

Look like you have to open the dashboard and see whether the flap is stuck to the hot air.
