Air not working correctly

Air not working correctly
I just replace my blower motor resistor for the second this year I believe . This time the resistor didn’t fix the problem completely. The ac never worked properly after I replaced the resistor the first time. Well it worked for a bout two weeks befor it started randomly shutting off. I would have to either wait for it to come back on or just keep turning it off then back on. Sometimes it would blow for the remainder of the drive others it would cut of within seconds. About a week ago now I noticed a burning smell followed by the ac shutting off and not coming back on. So I got on Amazon bought the ford part this time thinking that I just got a pos off brand resistor the first time, put it in yesterday and now the blower blows only on high, the air isn’t cool and you can’t change it to feet or defrost or anything. Any suggestions on what it might be now?

Well, now you have two problems: The blower won't work right and the compressor isn't running.
These advanced systems aren't as simple as the ones of days past. It's all computer-controlled and, if you don't have the required diagnostic equipment, service information, and background, it's pretty tough to do much more than guess as to what the problem might be.
As far as the lack of cooling, I "guess" the refrigerant might be low, the clutch gap may be excessive, the relay isn't working, there's a bad sensor, the computer isn't working right, or there's something else that's telling the computer to disable the system.
As for the high speed only issue, I "guess" the blower speed module or the DATC module is bad.
Since I don't know what diagnostic equipment you have, whether or not you have the service information or what you troubleshooting background might be, I guess that's about all I can offer.

Thanks! Check engine light came on on my what Home and now the o2 sensor is bad. Sensor 1 bank 1. I’m beginning to think I just need trade the truck in I was already saving up money to have the spark plugs replaced. I love the truck and it only has 135000 on it but I’m always have to fix something. I don’t have a lot of equipment so I’m planning to just Javier it diagnosed by a local ac shop and maybe I can fix it my self if not oh well. I appreciate all the help!
