Water in connectors for BLIS system. Did you put dielectric in all the rear connectors (drop the spare and grease away)?

Is one of your taillights cracked or have water in it? Hope not, they are north of $1400.00. Kevin

I posted about my 17 Lariat ultimate having the same faults with other system failures. Had it to the dealer they found no problems with taillights. Do you have anything else not working? Took me 2 days to notice all the things that are not working besides BLIS. Dealer suggested front interface control module. Has your tailgate wiring recall been done? Mine hasn’t but am getting it done. Have been told a lot of systems go through or are grounded at back of truck.
