How's it going guys so I have the P0650 code I researched it and a easy fix is to just take out the gauge cluster and put it back in I did that and my check Engine light started working again on the gauge cluster but as soon as I actually started the car and turned it off the check engine light no longer comes on idk what to do now can anyone help me out with this Im not good with electrical wiring so be prepared to make it idiot proof instructions if it's technical haha
