Hi guys I have a 3rd Gen 2.2D, the battery went dead when I was not around and my brother tried to jump start it and it went into limp mode because of under voltage. I cleared all that but the aircon fan now just keep blowing and its speed is not adjusting anymore. I have no multimeter at the moment, so I just removed the relay and it stopped exchanged it with one for the other fan and it continued to blow, which means the relay is fine. What else can I check?
