The right side usb port on my macbook pro isn’t working , not even a thumb drive is recognised , the left one though works fine.
please help what can be the reason and possible parts that can be faulty.
Is this a good question?

Any liquid damage? Does the HDMI output or SD card readers work?
The right side ports are on a separate I/O board that can be independently replaced. If the HDMI output or SD card reader works but not the USB port, you probably need to replace the entire I/O board: MacBook Pro 15" Retina Display Mid 2014 I/O Board Replacement and MacBook Pro 15" Retina (Late 2013-Mid 2014) Right I/O Board
If none of the ports on the right side function you could try replacing the cable instead: MacBook Pro 15" Retina Display Mid 2014 IO Board Cable Replacement and MacBook Pro 15" Retina (Late 2013-Mid 2014) I/O Board Data Cable
Replacing the cable is a bit of a cheaper repair so you could try it first, but if that doesn’t work then again you’ll need to replace that entire I/O board.

Good idea to check for debris in the socket and clean the contacts with applicable contact cleaner or 90% or higher concentration isopropyl alcohol. If you open up the unit, check the USB connector for cold/cracked solder joints, loose terminals between the circuit board and the connector (if possible) and any looseness of the connector itself.
