Why the "Check Engine Light" comes on when I turn the AC on?

Asked by Mar 21, 2015 at 06:45 AM about the 2008 Saturn VUE XE

Question type: General

Check engine light comes on once I turn the AC on and will stay on whenever the engine
is running unless I disconnect the battery cable and reconnect it. Even disconnecting and
reconnecting the negative battery cable solves it, it gets so tiring and bothersome. I would
like to know how to economically solve it permanently. Thank you all for any suggestions.

Most all times the light won't go away on it's own. It means one of the cars sensors is detecting a problem, prompting you to get it repaired or fixed. Some car's are't cheap to maintain as you found out. If you want economical for now, drive over to your nearest auto part store and ask them to scan the car. They can pull the 4 digit codes for you. Post them back here and we can help further.
