A/C Button Blinking

Need some advice on what to fix! A/C light blinks about once every two weeks, I guess the compressor is no engaging since air comes out warm. All I do is turn of the air and go crazy on the little button, I press it real fast on and off like 10 times and it works again for another two three weeks, do I need a new switch or a new compressor? air comes out iced cold when the button doesn't blink. Thanks for any help!

it means you are starting to run low on refrigerant. (R12 or R134a which ever your car takes)

It should be R134A. R12, i think, is banned and they required everyone to convert their R12 cars to R134A due to the environment problem or something like that.
You can check your refrigerant by buying a cheap 10 dollar gauge meant for checking refrigerant. It has instructions in the package so follow what it says. Also, only touch the L port and not the H port.

whats the difference between the L port and H port? where are these ports located? can i just add R134A if needed or do i have to let all the r12 out and then recharge with R134a?

Your car takes R134A refrigerant so do not worry about the R12. Those are for old old cars like the 80s. Not exactly sure what the L and H do because i never paid attention in class. But I do know L is what you touch. Not sure where the L and H is located but it should be easy to spot though. It looks like a metal piping with 2 caps one labeled L and one labeled H.

No that is why i said to buy the cheap 10 dollar refrigerant checker thing. Over-charging it will cause problems.
O also, i recommend buying the refrigerant with the adapter thing that connects to the L port.

The L is the "low pressure" side, the H is for the "high pressure" side. Only add refrigerant through the low pressure side (the fitting on the can won't even connect to the H port). Be sure to wear gloves and goggles (refrigerant in the eyes can't be good).

You should get a Chilton or Haynes manual for your car-- it'll pay off in the long run.

Welcome to the forums AlaricD.
Ok, i checked out Mitchell on Demand and it says your car holds 1.41 lbs. of refrigerant. That doesn't mean you put 1.41 lbs into the L port. Only put how much the gauge says when you check it. And AlaricD is right, L is low port and H is high port. Now i remember

Check your ac clutch relay. My buddy's car had the same issue. The local parts guy says he sells a ton of them.
