the only thing is that the haptic feedback is not working.. but I feel it worked before I closed the back case

@narimand Good! Is the touch bar and keyboard fully functional? Also can you take out the touchpad and clean that too, and check for rust.

and also my microphone doesn't work, I realised damage parts step by step .

@narimand Clean the LCD cable and post a picture of the socket on the motherboard, these often get damage.

Is there any relationship between a Lcd cable and microphone?

Check the underside of the logic board for liquid damage, and clean with 95%+ isopropyl if there is any corrosion. Sometimes on the 12" Retina (your model), liquid can get under this, usually around the CPU area.

Check the gold pins on both sides of the ribbon which goes from the trackpad to the logic board (curly one). If there is corrosion, this will be burnt, so it will need replacing. Also, check both sides of the cable which goes from the trackpad to the keyboard. It's very likely either the cable(s) or the trackpad PCB is bad if both the keyboard and trackpad aren't working, since the keyboard is plugged in through the trackpad.

If the keys are sticky, the keyboard will likely need replacing too.

Regarding the microphone, check for liquid damage around the small headphone jack board where this plugs in. Sometimes the microphone cable can be burnt, or the board is bad.

To be honest, I would recommend taking it to a repair company which has the testing parts available, otherwise you will find yourself spending a lot of money on parts to test. Try out what I said first though, to see if anything stands out :)

every parts now are fine , but my microphone won't work

@narimand try the audio board first, should fix the issue

by

I cleaned it but nothing happened

by

@narimand yes it is probably bad. If it had liquid on it, it is definitely going to be bad. This board is responsible for the audio so it is either this or the microphone itself, which is less likely.

All the connectors looks fine, so honestly I have no clue. Maybe @refectio could help?

I haven't opened one of these up yet so I can only speculate. The first picture definitely shows contact with water. The damage may be behind that board as I can't really notice any obvious damage from the picture.
