Hi I'm hoping someone can help. I've scanned my car and brought it to a shop and I had a high temp sensor bad. I got it changed out hoping this would fix my eco button staying on but it didn't... Now I'm thinking, is it possible I'm low on freon? I've never recharged it since ownership probably 8 ish years ago and since I purchased with 30k on it I HIGHLY doubt the previous owner did either.I have a gage to test the low side of the AC unit but of course since only the fans would blow i'm not sure if that would even give me a proper reading?

I heard it could be the switch near the front end of the bumper but since I've scanned everything I'm assuming it's not that?

Any help would be really appreciated

 

welcome
