Hey guys I'd appreciate any help you may have about the randomness of my air conditioner. Some days it works like a champ....some days it doesn't. Has any of you experienced this and have a solution or any ideas of what to fix on it? I am afraid its electrical because when its working its cold. Other times when its not working it just blows hot air. I am hoping for a quick fix.

You really need to search and at least read these threads:

If you get heated air, then you have a very common problem which is that your DCCV is starting to fail.
If you don't get heated air, but just get not-cooled air, then you probably have a failing evap temperature sensor.

Well that was about the best use of 1.5 work hours I've had all day! Thanks for those links and the advice. It looks/sounds like I need to change out the DCCV. I have a 2000 model year, do you know what the part number is offhand?

I don't know it off hand.
When you replace the valve, be sure to correctly fill and bleed the cooling system.
