#1 of 159 1994 Honda Accord A/C problem
Jun 30, 2006 (7:06 pm)
I bought a freon charging kit and charged the system. When I turn the A/C on I hear the compressor kick on. It blows out very hot air. The drivers side fan kicks on every couple of minutes. The passenger fan isn't on. The wires from the driver fan looks like they go to the compressor unit, so I figured the other fan was for the car cooling. I am not sure. Anyhow, I am looking for advice on what I could check. Why after charging the system is it blowing out very very hot air? Thank you for answers.

Even if your A/C isn't working, if you have the temp lever set to the coldest setting, you should get air the same temp (or close to) the same temp as the outside air temp.
The lever for the hot-cold control opens and closes a valve on the heater lines. If that valve isn't closing off, your basically running the heater the same time your trying to run the A/C.
Trace the heater lines, usually by the firewall, you will find the inline valve. Make sure the lever on it is moving when you move the hot-cold lever.
The second cooling fan only runs when the A/C compressor is running. I would visually look at the compressor to verify it is actually running (center is spinning).

Thank you for the great advice. I started to switch the knob to change it from hot to cold and try to listen for the valve to open or close. So for some reason I decided to take the knob off. Low and behold and simple problem. The inside of the knob was broken and not actually turning the switch. I got some pliers and turned it from hot to cold and the air was cold as could be then. And all this first part of summer we have been driving with the windows down suffering in the heat. Thank you very much for pointing me in the right direction. Have a great summer.

This switch breaks a lot on this age of Hondas.
#5 of 159 Another Accord AC problem
Jul 02, 2006 (4:38 pm)
The AC in my 1994 Accord works fine but my problem is the throttle does not kick up when the AC is turned on. I am unable to locate what is called the AC idle boost valve. Are they talking about the adjustment screw on the throttle body? I have already reset the ECU but this had no effect. The real problem is that with out the idle boost operating the car stalls when stopping. Any ideas? Thanks.

Yep, my 1996 is on knob #4, and not with heavy use, mind you. They charged me for the first one, but haven't since then (for 3 and 4).
#8 of 159 2003 Accord AC Compressor Problem fixes?
Jul 20, 2006 (9:01 am)
I've heard the AC compressor can go out because of insufficient protection around the compressor.
Has anyone had this issue or found a way to fix it?

The temperature knobs break because the cable will not move (binds up) as fast as you can turn the knob. Try this: turn the temperature knob only until you feel resistance (usually about half way), wait a few seconds, the cable will loosen, then you can turn it the rest of the way. I went through a few knobs before I figured this out too.
