All I know for sure is I wasn't having any issues. Then I took it to the car wash then dropped it off for its first service. Then they tell me that the display is not working properly. Not showing that it is in 2wd, 4wd etc. And that the cooling fan wasn't kicking on. They told me that it was the way I mounted the light bar. I jumped off the wire from the ignition switch to operate a relay that supply's power to the switch panel from the battery. Ran it all deer season and never had an issue with the indicator or the fan. So I figured it had to be from the pressure washer. I still haven't had an issue with the fan not working so not sure why they had a problem with it. It is shifting in to all drive modes. Just no indication on the display.
