M201 Hotend Jammed

[JaxenWP]

Hi, It has been roughly 3 months since I used my A20M and I'm running into some issues with it that were not there before. Both sides of the M201 hotend were jammed with filament. I fixed one of the sides already with a cold pull but the other side will not move. I attempted a cold pull on it and nothing comes out with it. I replaced the nozzle already and it works fine with the side I already unjammed (the right side is what I fixed). No matter what temperature i set the hotend to, it will not melt or soften what is in the left side. Is there anything I can do about it?
