Hi there, a couple of months ago I replaced my clutch fan in my 2003 Chevy Trailblazer however the check engine light has never gone away. Every mechanic even Chevy ones all tell me the same thing, that it's the clutch fan. Do I really have to replace it again? Could it be something else? I failed my emissions due to this which is stupid since now I've started to get pulled over for my inspection sticker yet none of the mechanics I go to can fix my vehicle and frankly I don't have the money to keep paying them for nothing. If anyone has any ideas please let me know, I need this vehicle to get to and from work or else.

Welcome to the forum, can you provide more specifics on the error or code?
I am not aware of a "fan clutch" causing a check engine light other then a possible over heating issue...
Anymore details you can provide would help narrow it down...
Is it possible its P0641? for the engine cooling fan speed sensor?
My 03 Trailblazer had problems with the fan clutch. It was replaced by the dealer but was never right. Finally the relay caught fire and burned up the whole fuse box. Dealer said that never happened before and refused to repair it under warranty even though I had paid for extended full warranty. A phone call to Customer Service took some time but they said it should be covered and told dealership to repair under warranty.
