Could be your cabin air filter. When was the last time you had it changed. See Air Filtration System, under Climate Control in your "Owner's Manual". (The filter is hidden behind the glove box.).....
It depends on what is wrong with it. We need more info please.
It is in the fuse box under the hood (at least for the 1997 Subaru Legacy) Also for my 2007 Outback so you can assume that it is in the same place on most, if not all, modern Subarus.
The 2002 Subaru air conditioning drain line can be found on the bottom of the air conditioner compressor. The air conditioning drain line routes condensation to the bottom of the engine compartment.
Very likely that the ac compressor is locked up and the belt is slipping.
you need to replace the fuses in the computer
I had this problem about a year ago. Turned out to be all the bulbs were burnt out on mine. There's 3 (or 4) miniture bulbs that are accessed by removing the heater control.
The ac pump may be seized up.
NO,I recommend that you remove the radiator and anything on front of the engine,ac compressor can be move Whit up removing the lines may sure too aliment all the marks on the pules and time belt
idler pulley is adjustable it rides on the same belt.
turn on the ac and open the door or window
You can turn the temperature of the AC up but if you turn the fan part of the AC up "high" or "low" it will only make it colder.
why does my ford focus over heat when i turn the ac on
