I like to think that I have a little automotive mechanical skill. Unfortunately, I purchased a 2005 Ford Taurus back in 2005... Other than having to replace the altinato, I've had to do nothing to the engine except basic maintenance. (Oil, tire, belts, spark plugs, et al.)

Unfortunately, I'm starting to run into problems. (I'm going to skip the issues with replacing the radio because I'm pretty weak at electrical issues all in all.) Today I tried to recharge the AC. (It's not cold.) Ran the engine, turned the AC on max, and hooked up the refrigerant to low-side service port. Should have been good, but when I hit the button there was no flow of gas into the system.

So... What is the problem that I'm looking at? I don't have a tool to check the pressure in the AC system. (I'll need to pick one up tomorrow.) I'm hoping it's not a mechanical problem, as I prefer a cheap solution. But if I can't recharge the AC...

Without any gauges it would be a guess, but if your high and low side psi are about the same probably a compressor. If its not taking a charge I would start at the TXV or thermal expansion valve. You also could be over charged, check the front of your condenser maybe melted plastic shopping bag melted into it I have seen this before.

You probably have a bad o ring in a line. Find a competent ac shop and let them fix it unless you have the line tool, vac pump, gauges and refrigerant. Replace all serviceable parts.

Hi Rec4LMS. Is the compressor clutch engaging? There's a pressure switch on the lines that has to make before the clutch will actuate. If the freon is real low, the pressure want be enough to make this switch and the compressor want pull the pressure down enough on the suction side for it to be lower than the freon container you're trying to charge the system with. Just a wild guess. And if you're charging it with those small cans, try putting the can in a container of hot water and run your garden hose on the condenser coil while you charge the system.

Too much refrigerant can have as many issues as too little, starting with blowing seals. The only certain way to know if you've got enough refrigerant is to weigh it, like the pros do. Depending on how long the system has been open, you proably need a new receiver drier and the POE oils commonly used can undergo hydrolysis and themselves become corrosive in addition to the water trapped in system. Getting a pro to charge it with the right equipment can save aggravation and damage.
