I am guessing the switch up by the steering column is your fan switch? Also when those trailers are way too low do you dump the airbags before backing in? I don’t remember hearing the air sound. If you aren’t give it a try it does help with those low trailers. And will make it easier on the driveline and clutch. Just a thought.
