Any ideas why after filling my ac with freon per the specs according to this forum it doesn't come on?....No heat no ac no fan motor... fuse is good...I ran it for a few minutes after filling it and it was nice and cold
Filled A/C with freon and now it won't work

I am a little confused about your post. First you say it doesn't come on but then you said it did. You wouldn't have been able to fill it if it didn't come on.
No fan? Is the low pressure line getting cold?
Not enough information to know for sure but it sounds like you have a fan issue...maybe the fan motor crapped out?

Sorry ....it worked fine while I was filling it (because the air wasn't cold enough). I ran it for a couple of minutes after I was done filling it and air was noticeably colder thought great job Jason you got something right...... This was yesterday...drove it today and nothing....low pressure line is cold

@gatertamer with respect dude, you have a huge resource of knowledgeable people on here who are willing to help but you gotta give us something to work with! Give us some context - what model do you have, what condition is it in, what happened to lead you to filing the A/C and what are the symptoms of what went wrong. Make the effort to tell us the unvarnished story and maybe we can assist...
appreciate it brother....the profile says what I have...it's in great condition...it was low on freon and not blowing very cold... compressor cycling too often..... everything was great while filling it worked like it always has as I said before I ran it for a few minutes after I was done cold as hell like usual...now there's no blower no heat no cold nothing what else can I tell you?....I did notice a small leak about 6 months ago.but it was winter time.

Without knowing what your pressures are, it's just shooting in the dark. Suggest you pick up a gauge manifold from HF or Amazon for <$100 and start your troubleshooting there.
That explains it. Freon is the wrong refrigerant.
Like R12, which is the original ozone-depleting refrigerant, R22 is marketed under the brand name Freon, and it's one of the earliest CFC alternatives. Its chemical name is chlorodifluoromethane, and while it isn't technically one of the CFCs banned by the Montreal Protocol, it belongs to a closely related class known as hydrochloroflurocarbons (HCFCs). These types of refrigerants also contain chlorine that can potentially find its way into the upper atmosphere. Effective January 1, 2020, production and import of HCFCs like R22 were phased out.
R134a belongs to another class of CFC alternatives, called hydrofluorocarbons (HFCs), that don't contain chlorine. Its chemical name is tetrafluoroethane. It isn't the only CFC alternative on the market, and it isn't the best. HFCs may not be ozone-depleting gases, but they contribute to global warming, and R134a has more global warming potential than other HFCs, such as R152a. This fact led the European Union to ban R-134a from use in new motor vehicles, effective in 2011.
It doesn't sound like a pressure thing to me...it sounds more electrical..... one day it's working fine..next day absolutely nada...no heat either
That's a separate issue. Maybe the blower motor wires are melted or the resistor is going bad.

Damn if you're not you should be a professor.... that's quite impressive
really
The fact that the indoor fan is not working I would remove the climate control console and check the condition of the wiring and where voltage is present and not present.
From there you can determine what your next step will be.
This schematic from the FSM should assist you in troubleshooting.

Thank you
...I replaced the climate control console about a year ago..? but sounds like a good next step
If you have no blower speeds at all. The first thing I would check is the connectors at the blower motor and the resistor. One of them is probably melted.
The refrigerant charge and the pressures in the system have absolutely zero relationship to the fan coming on so it would appear to be a big floppy coincidence.

Big coincidences like this (two different faults manifesting at the same time) happen with monotonous regularity in old systems to the point of the word coincidence no longer having any valid meaning! Sometimes one fault triggers the other and all your effort goes to resolving the symptomatic fault, other times the old "million to one" shot happens and both faults just manifest in sympathy with each other. All. The. Bloody. Time.
And also I would introduce you to "but its a brand new part so it cannot be faulty..." and her lesser known accomplice "the previous owner just replaced that thing so that cannot be what has gone wrong..."

If you want help diagnosing a problem you need to be more forthcoming with information. I'd like to be of more help but my help will be limited by the limited information given.
Since you say the low pressure line is cold when running, I'm going to make an assumption your AC system is working correctly. The fact you have no air flowing out of the vents means you have a problem unrelated to the actual AC system. I'd start diagnosing the fan. Personally, I suspect your fan motor has failed but it's always possible it's something in the electrical circuit has failed.

Boog, you are mistaken. Freon, originally a trademark owned by DuPont, is currently a trademark of Chemours. Chemours applies the Freon trademark to numerous refrigerants, including R134a. I know this because my 30lb tank says "Freon 134a" on it (not my actual tank in the photo below):
I used to think that Freon applied only to R-12, but Chemours continues to use it for each new "greener" refrigerant that the EPA pushes on us. I've heard that there is a push to require that CO2 be used for refrigerants in the future. I wonder if Chemours will call it Freon CO2?
CO2 is out there and its properties make it expensive to execute. Pressures are crazy high which can be dangerous in a rupture, components have to be special because it's supercritical at the temperatures required for the condenser to work, and it's a pain to work with because when you evacuate the system to service it, it turns to solid dry ice at like 70psi and then takes forever to absorb enough heat to sublimate.
An HFO, R-1234yf is taking off in automotive, as it's similar pressures to R-134a, has a very low GWP and is only "mildly" flammable. Looks like Chemours calls that one "Opteon". Maybe Freon is the trade name they use for "whatever refrigerant the government doesn't want us using anymore"
