A/C not working
I have a 93 Accord that I bought recently. When I test drove the car, the air condition seemed to work just fine......very cold air came out thru the vents (although it was a very cold day). Today I was driving and turned on the air conditioner and just vent air was brought into the car. The green A/C light illuminated on the button. When I got home, I turned the button on and off and did not feel the car bog a little as most cars do when the compressor turns on.....also the cooling fans did not automatically turn on.....like they do in some cars but not sure if they automatically turn on for an Accord when the A/C is turned on. So, I am thinking it is probably a problem with the compressor getting a signal from the switch to turn on. I checked the fuse inside the fuse box inside the car and it appeard fine. Any suggestions from anyone as what I should check from here. Jabe

RE: A/C not working
you are correct in assuming that both fans should come on with the a/c on, if the fuses are okay I'd check to see if you are getting power to the compressor when the button is clicked on, if so it may be a problem with the compressor that can be diagnosed further, if not then might be the switch.... you may also have fuse under the hood that needs checked....

The compressor and fans will not come on if the freon pressure is low.
A quick check is to unplug the pressure switch,it is located just in front of the power steering pump area, on a small tube. While you are there look for oil in the pressure switch housing. They are known to leak.
Then jumper that plug with a small wire and try turning on the A/C again [engine running] If the car is low on freon the compressor clutch will engage and the fans will run as long as the switch plug is jumpered.
If you have the system recharged, be sure to replace the oil and put in flourescent dye; The freon leaked out somewhere and the oil goes with the freon, having the dye will make the leak easier to find.

I agree with honda dude, there is a possibility that there is a freon leak somewhere, check your hoses for dye, ( color black) to and from the compressor,
Bring it to a deal and let them conduct afreon pressure check.
