So I vape in my 2015 TLX when I'm driving. Stupidly don't roll down the windows much in the winter because it's cold.

I just noticed recently that my LKAS doesn't work any more. It will turn on and give me the clear lines but never locks on to them. Does anyone know of a way to clean the cameras? I know some people posted about having to replace the windshield to fix the alignment but do you need to remove the windshield to clean them too? Any advice would be appreciated. Thanks.
