2012 F-150 Parasitic Drain on Fuse position 52
Fuse description in manual: "Run/start – Electronic power assist steering, Blower relay coil". I know the drain is on this fuse, because the drain stops if I pull this fuse. I tried replacing the Blower Motor Resistor BL3Z19E624A and that did not solve the issue. I also tried pulling the Blower Relay in position #3. The drain continued with this relay out. So, I'm thinking the drain is coming from the power steering. Any suggestions how I can further isolate the issue to the faulty component? I'm a diy-er. I've done work on my cars before, but I'm not a trained mechanic.
