Hello I'm from Nigeria. I have a 2012 accent with 100,123km on it. At idle, the rpm needle is just at the mark below 1000rpm. The AC compressor doesn't engage when turned on from inside, though the light on the AC button inside doesn't go off once the AC knob is turned on. Whenever the AC compressor is connected directly, it comes on but the engine jerks and goes off. Someone please help. The AC fan blows just fine though it blows warm air since the compressor ain't engaging.

Did you check to see if you have the correct amount of pressure for the switch to let the AC compressor to turn on?
Check the refrigerant
Then check the AC compressor/clutch ...

I went to see an A/C specialist today and he suggested I should meet an auto electrician to connect the compressor directly using a relay and a switch. He said that the pressure was normal.
Still confused if I should go ahead with that.

We have an auto electrician. His name is @AUTOSPARK.
He is very good and experienced.
He is also sometimes tough to understand
But, he probably is the one to ask for specific help

Find the ac compressor relay
Determine which is ones are powers
And which ones are control side and which ones are load side
You might need a schematic
Should be able to figure out how to wire it up so you can manually turn on compressor

Isn't that basically what you did before and it made the engine quit?

How did he measure the pressure? Did he use a diagnostic scan tool or use a mechanical gauge?

If he used a mechanical gauge that tells you what the pressure in the system is but it doesn't tell you what pressure the A/C control module is seeing. If there's a problem with the pressure sensor circuit the module won't know what the pressure in the system is and wont activate the compressor.
