hello all ! my a/ c is not blowing cold air , I have 95 c220, it worked last year but this year it doesn t . I wolld like to refill it myself but not sure which port I gotta use. I also got the code from the control, #7 (refregrant pessure) shows " 04 5 " .... what is this mean? do I need refrigerant? the twin fans never comes on. should they work when I turn the a/c? the compresser workes fine , I tested. please help......thank you

Here's a website that has pretty good information on what you're asking about recharging your own car. You can find their product in most auto discount stores like Autozone, Pep Boys, Discount Auto and others. Pay close attention to the part about making sure which coolant you have in your car now. Everything else is pretty straight forward. Good luck.

hey, just charged mine but had to replace the reciever/drier though. the one that sits in the front next to the fans is where the refrigerant needs to be evacuated. the one that sits down next to the engine is where you charge it. The hook ups for the charge kit are idiot proof (they're different sizes) The car requires two and a half cans (roughly)

Since your a/c was cold last year and not this year, you may have a leak......so don't get your hopes up. Make sure you have an expert with you when you try to recharge it though. Good luck.

What refigerant did you use to refill and how many cans did you go through? I assume that you used this setup or equivalent...

I don t remember what the can said, but I bought it from advance auto parts, they had millions of them right front of the desk. it was mixed with oil or something. I ll take a look at it when I go.take care

I tried to charge my a/c in my c220 today. I located the two ports. My gauge that I bought from Auto Zone seemed to fit the valve ok but didn't seem very snug. But I realize it will not fit on the wrong port because the other port is too large in diameter. I emptied a 12oz can of freon but not sure If it really got sucked in properly. I got a reading from the gauge at about 20lbs for a few seconds but then it just went to zero. The air did not get any cooler. Any suggestions?

the refridgerant is called R34a for 95 c220
