2003 honda accord, the air conditioning panel won't switch modes. It just blows out the regular fans but I can't change to a different mode such as defrost, top fans and feet fans. Everything seems to light up when i press the button on the panel and it is able to go from cold to hot perfectly fine.

this means that your a/c has a leak somewhere in it....or the a/c compressor has gone bad.....you can check the a/c charge with a guage you can pick up at your local automotive store. if the charge is good then chances are that your a/c compressor is bad....kindof a costly fix.

I ad this problem fixed and it cost $35. Apparently, this happens when the Freon level is low for some reason. They refilled the Freon and now I have AC on both sides. Don't forget to replace the internal filter in the glove box.

This is a common problem when the AC system has a low charge.
If this is the case, you have a leak somewhere. Do not try to fix it yourself without the proper equipment.
