saturn vue fan running all night battery almost dead

 

Hello Itsmeagain1956.
Not sure why you are posting about saturn vue in an acura forum, but since I own both an acura and a saturn vue I will try to help. I think you should start by posting this question on automotive forums. They have a sub forum just for saturn vue. Vue - Automotive Forums .com Car Chat

For the mechanical standpoint I am assuming you meant the radiator fan. I would start by looking at the relays. Probably in a fuse box under the hood. Look in the owners manual to find which relay is for the fan that is running. When you find the correct relay try tapping on it a few times to see if it is just stuck. If nothing changes you can at least pull the relay out and that should stop it from running and draining the battery overnight. Just be sure to plug it back in before driving. Relays are available from most auto part stores and only cost a few dollars.

Good luck.

 

the vue and acura share engines. so that's probably why he made the connection to post here in an acura forum. I believe they share the J32/J35.

i agree with you captkirksby, it might be a relay.
