So i'm having the fans spin but never ramp up speeds. i know the part is discontinued so my only hope is t find a working one in a u pull it but my questions are... is there a fuse or relay that would go bad that would cause this? I read that once it has been replaced to fill the resevoir with fluid and put it under vacuum for 3-5 min then start the AC. Then i read most say they just swap in a new one, fill the fluid and it works. Anyone that has done it not just repeating what they read would be greatly appreciated.
