Well it's been getting pretty hot out here since the past weekend here in VA. The humidity has been killer. Usually I drive around with the windows down when I'm putting around town by myself. A lot of the time, I take my four-legged best friend around with me whenever I take a drive. I turn on the A/C for his sake when it gets too hot when we're both stuck in traffic, but lately it feels like it's not cooling as it should. I thought it wasn't cooling 100% since it was on idle, but I also turned it on while I was on the freeway but that didn't make a difference either. I have to leave it cranked all the way up for some effectiveness. I have no clue when it comes to A/Cs so I could use some schooling.

How often is the freon supposed to be refilled? Can I buy those refill kits they sell at the auto stores and refill it myself? What should I check for? Is this something I can fix myself or will I have to take it to the dealership and get it done? TIA:)

Well, if it is low on freon, you can service it yourself with a kit from the auto parts store. The thing is, you need to locate the leak area and determine if it needs fixed or not. When an A/C isn't used very often, the front seal on the compressor will leak, sometimes it blows out completely. Sounds like yours is simply leaking an bit.

Buy the service kit along with a can or two of freon and one small can of leak-detect/oil. If you want, you can come out to the house and I'll show you how to service it up. I have the hose kit with gauge, but you'll need to buy the freon and oil....

That A/C should be spitting out ice-cubes when it's set to 70. I think the cabin thermostat used to regulate the interior temp & 'climate control' system (if one exists) is way outta whack. I have to set it to like 77 degrees to have it be like 69-71F in the cabin. I don't know what that's all about... I mean it's better than it not getting cold enough. I know nothing about A/C's except it does sound like your freon could be low. I'm not 100% on what goes down when the compressor is on it's way out. I had one go on me way back when, and I think you could hear it whining or something, but it was ages ago.

Definitely Forzdaman. It's not going to get cooler anytime soon so I gotta act fast. Thank you, sir!! I was actually planning to go to your house sometime next week and free load off your fender rolling tool for my wheels. :rolleyes: My rubber comes in this week and I plan to get them mounted but I'll be out town this weekend.

I also did that trick you mentioned, Dougeman. It's funny that you mentioned the cabin thermostat deal because my neighbor has a NA 6 (not sure exactly which one) and had that funk going on too, but his was cold as ice.

Im not sure on mazdas but for gm's anything 20 degrees below ambient is considered good. As for it not being cold, you def have a leak somewhere and it is a slow leak. The only way to get a dye in the system is to create a vacuum. Idk how one would go about doing that without an A/C machine. If you decide to do it yourself, since it seems like its a slow leak, you may need to inject the dye and drive it for a week and then check for the dye. Be careful tho as any water will wash away the dye. Slow leaks are a pain in the ass to find for that reason. Youl also need a dye light obviously to see the dye. But ya in all honesty its def worth it to bring it to a shop and just tell them to recharge the ac and add a dye. If your trying to save money you can just find the leak yourself instead of having them do it. But ya like I said if its a slow leak they most likely will tell you to bring it back in a week.
