2020 Limited AWD - Blizzard Pearl/Black
Im curious if you could get the voltage to those wires. could it be as simple as putting the fuse in where it would normally go? or just making a connection some where?
I spent an entire weekend recently tearing apart my dash and tracing wires. I even pulled out the ECU and verified everything was pinned out and wired correctly. Everything is installed that should be and turned on in Techstream, it just seems the ECU has some kind of logic that disables features that shouldn’t be on certain trims or if it detects certain things missing. Either by VIN or some other method. Probably some kind of fuel saving strategy. No one knows for sure.
Folks that have the XLE Premium with heated seats claim their wiring works and are able to install the lights. They also work in the XLE Hybrid. Seems the LE and XLE are just out of luck.
