Headlight Switch problems of the 2010 Jeep Liberty

I have a 2010 Jeep Liberty sport and it's headlights continue to go off on me while on the highway and it's only noticeable at night in which is not safe. I've changed both light bulbs in which worked and then went out within 20 mins agai at night on the highway. Then I changed the 30amp/relay. Then I changed the dimmer switch. All of this did not work. Then the dealer changed the windshield that is located on the right hand side and it worked for about a week with the passenger side light going out but working when I shimmy the cord of conductor. But like it did previously it's now not just the passenger light as both lights are again not working. And they are starting to flicker then just goes out altogether to where now the shimmy is no longer effective. Now I've done all I can do on the electrical realm but it seems as though everything I've attempted is just temporary or does not work at all. What is the problem. Please help!.

2010 Jeep Liberty limited 4x4 began to intermittently start and not have headlights, sometimes the lights would not come on at all, other times only the parking lights would work, and other times only the headlights would work. It was taken to both a Jeep dealer as well as a local garage and no one could find an issue. They tried replacing the switch but this did not help either. Eventually, the issue got worse and the lights have now shut off while driving at night on highways, local roads, ect. And has become unsafe to drive. Jeep still claims to never have seen anything like this however multiple complaints exists online for similar complaints, a local garage told me about the tipm issues and even upon suggesting the replacement of this part, Jeep insisted this couldn't be the issue. Now the lights are really acting up, shutting off while driving, flashing frequently, only parking lights work sometimes, sometimes only one light works, and other issues are beginning (starting randomly, horn / alarm randomly going off,ect) Jeep still refusing that this is the issue and wants to replace / repair other things first. Currently looking into replacement tipm personally, as at this point, the Jeep Liberty is unsafe to drive, especially at night.
