Go in the fuse box, below the hood, locate the ac fan relay (according to the schematic), swap it with another one(with an equal votage and amp value). start your car and turn on your ac. Then leave your engine runing. pop the hood and check if the fan is running. If the fan works, your ac relay needs to be replaced. good luck!
