Air conditioner blowing warm air

First found out that the fuse was blown (the clutch wasn't turning at all), so I changed that and the clutch began working. The air seemed to get a little cooler - it was definitely blowing warm air when the clutch wasn't running.

Next since it was blowing warm air I got a can of refrigerant from Walmart (I think it was Air Pros with the gauge on it).

I put the gauge on the low side (L) and didn't get much of a reading. I actually think I didn't have the connector on it real well. So when I got it on correctly I started adding the refrigerant (so basically I didn't really get a before reading).

When I started adding the refrigerant I would hold the lever for about 15 seconds then looked at the gauge. I did this a few times and the gauge was in the green (the right area).

So only then, after I was about done with adding the refrigerant because it was near the high end of the green area did I hear for the first time that the clutch was starting to stop for a few seconds and then start again. Some website said this was OK and that clutches do that, but I am still a little skeptical - let me know your thoughts on that please.

I got concerned, so I shut off the air conditioner - oh and by the way the air never got colder.

I am not sure why the clutch only started stopping and starting after I put in more refrigerant. Any ideas about that?

So I just looked online and listened to a video of yours and am not quite sure what next to do.

The fans come on under the hood near the evaporator and radiator, I guess to keep them cool, so the fans seems to be working okay.

The clutch is working (still a bit unsure of the starting and stopping though.

Having the air on high in the car works, meaning it blows air, not like there is an abductor issue (might be the wrong word).

OK, lastly I wanted to mention that the video I watched mentioned the evaporator as another piece, but didn't say much about that.

I wanted to say that at least a year ago I hit some kind of animal on the highway and I had to have some of those front pieces replaced, I know the evaporator was one of them.

My only thoughts at this time is that, as the video mentions, that the pressurized air goes through the evaporator (again, I think).

I mention the evaporator because I really don't think my A/C has worked really good since then. I know I had a shop put refrigerant in my car, but I can't remember if it was before or after the accident and replacement of parts and I didn't even then think it helped a lot.

Is there a way to tell if the evaporator is clogged or needs service or anything?

Thank you for reading this - I am not sure what else to do, any ideas would help.
