This is a 4.9 v6 only drive about 1500 mi per yr. Last year the
ac blew snowballs, but this year it is only blowing cool (not cold).
I suspect low on Freon, but have never experienced adding Freon
before. Is this something I can do without much problem? I see
only one connection on ac line.
I'm sure there are 2. One on high side and one on low. They sell a recharge kit for A/C units. You should ask someone there to show you how. If done improperly it could be bad for you or your Ford
Saw a TV ad last night for AC Pro, a simple one can R134A system that has the quick connector and a pressure indication to show status. Trigger operated, pretty simple, but you pay for the convenience - about $40 at the auto box stores on average. Or one of your local tire/service centers like Firestone, Goodyear, or any independent garage can check your pressure pretty cheap, and then top it off if it's low on refrigerant if you don't want to buy the hose.
The pressure is mostly dependent on the temperature outside. The gauge (comes w can) will have temperatures and corresponding pressures. If I remember the instructions: Shake can, Set dial to the appropriate temperature, Connect to the correct fitting (High and low pressure but it only fits on the appropriate fitting), turn upside down and with a/c compressor running on high pull trigger (Where gloves in case of leak). Stop when pressure is at desired. The line should be sweating. You can buy cans that state they swell the seals and help stop leakage.
