I put Freon in Ac, but it’s still blowing hot air, when I turn on car and hit the AC button it blinks three times, I can’t figure out why it’s still blowing Hot Air

Take it to a professional. Air conditioners aren't plug and play things, they're complex devices and are extremely dangerous if you don't know what you're doing. They're also extremely expensive and labor intensive to rebuild if you destroy something. 


Excellent point. It sounds like we have yet another "I filled to the green why doesn't it work" situation here. The proliferation of those "refill cans" is like a plague.


They are. The big chain discount parts stores aren't helping this. I keep hearing an O'Reilly ad about A/C Pro being on sale to make your air conditioner blow cold again, like all you need to do is hook it up and go. I cringe every time I hear it. I'm really surprised they did it, with all of the problems they can cause.
