What can be the cause of Trackpad problems on Macbook?

Question

macbook

there are problems with the trackpad - from time to time the cursor loses control, it seems to be constantly pulled to the side, jumping and twitching. These signs disappear just as they begin - suddenly. Physical influences from the outside do not affect in any way (I tried to knock with my finger, clap my hand, etc.). I noticed a connection - this happens when the laptop warms up from heavy tasks. Tried resetting SMC and PRAM. AHT found no errors. OS reinstalled to a clean one. I tried to disassemble the laptop and clean the trackpad from the inside.
Does it make sense to buy a new trackpad?
Can it be fixed by replacing the trackpad? How can you personally help in exchange for money?

Maybe you just need to clean the laptop so that it does not overheat. In general, they will be able to tell you for sure at the service center after a complete diagnosis, for example, it is free at apple4you.ru .
