why does the check engine light come on when I turn the air conditioner on my 2007 town and country
To scare you into the dealer. Is the a/c cool and not cold? If so then it needs charged. (The A/C)
Footnote: everything electronic is wired into the ecm. So the light is triggered for loose gas cap. For example. That way you can't bypass anything w/o proper parts/repairs.
