2018 Trailer Brake Insanity
We bought a used 2018 LT two months ago, told by the dealer it was equipped with the tow package. Last weekend, had Camping World install a hitch and brake controller to tow a camper. They could not get the Tekonsha controller to work! Would not get signal to the seven pin connector at the hitch... told us a dealer would have to flash the Body Control Module to enable the connection. Called the dealer. They won't touch it---because it's an aftermarket part. There is NO "Genuine GM Parts" brake controller available. NOBODY seems to want to take ownership of this issue.
Has anyone else experienced this insanity? If you found a solution... what was it?
