According to the FSM yes, it’s a yellow green. I’ve just been studying the FSM to try to find commonalities to my 8 codes. I’m trying to figure out what body ground A46-18 uses and where it’s located. It passes through multiple fuse boxes so is each fuse box grounded separately? Thanks for the diagrams!
 
ultimately, under the front passenger seat on the forward seat rail halfway between the mounts. I think there's three gathered up there. All white and back wires. From the air mix, and both ac temp sensors through some other things.
 
Did you ever get this figured out? I have replaced my AC Amp once, AC worked fine for a couple months, and now same problem has occured. Can you tell me how you pulled all those codes? Thanks!
 
Thanks for this information. I tried to do this, but unfortunately, those buttons are the ones that are currently inoperable, due to my AC issue. Do you think the dealer can pull the codes by hooking the LC up to their diagnostic machine? Thanks!
 
Were you ever able to figure this out? I have similar codes. My outside temp display is showing about 30 degrees below what really is outside. This problem seems to happen when it rains. Thanks for any ideas. I love this truck-- but am ready to get rid of it, due to the HVAC/NAV System ghosts!!!
 
My problem turned out to be in the passenger footwell junction block that is mounted on the inside of the fender area just in front of the door. Most likely a bad windshield replacement that caused a water leak onto the fuses and plugs.
