That's why I think that those two are regulated differently somehow. They are the only LED backlit lights on the panels. LED reaches full brightness at a far lower voltage than the incandescent lights that are everywhere else. so I'm thinking they are regulated differently at some point. The LCD Nav screen adjusts with all of the other lights. I'm thinking that these two specifically have a separate output on a circuit board somewhere. That's why I was thinking it could be an issue with the rheostat. There must be a separate, shared output for the voltage to these displays. Whether or not that output would be on the board in the rheostat assembly or at some other place in the dash is another question. To be honest I'm thinking that it might be in the rheostat simply due to the fact that, on occasion I can adjust the panel lights all the way up, then back down and the Temp and Odometer displays will dim back down for a few minutes before going full bright again. other times, however, they are unaffected.

Hi Everyone. My 2010 MKX developed an issue in which after 5-10 minutes of driving at night the Odometer and Digital climate control lights suddenly go full blaze as though the headlights were off. The NAV screen stays in night mode and all of the other dash lights are adjusting with the rheostat for the cluster lights that sits to the right of the headlight switch. I realize that these displays are LED and therefore are using a much lower voltage for adjustment than the other panel lights, so somewhere along the line something has those two on a circuit together adjusting independently of the others. Any Ideas? Could it just be some component of the rheostat that's malfunctioning after it "warms up"? I hate to spend money on a new switch assembly and it end up being something further down the line. but I find the brightness to be distracting while driving at night. Thanks for any input.

I wanted to add that I was able to replace this clip without removing the back seats. I popped out the cargo management cover and the cargo bin on the right side, then used a T20 Hex key to remove the screws holding the cover over the spring assembly. The screw facing the rear was easy to remove. After that I pulled back the cover and pulled the spring while pressing the power assist button to cause the seat to fold down, making the second screw more easily accessible. Push the cover both forward and down to unhook it from the seat bottom, pop the new clip into place and pull back the spring to get the cable end into the opening. I have basketball player sized hands, so I think this would be even easier for a normal person. *Edit, right vs left.
