I have a 2009 F150 FX4 SCREW. Since last summer I have had a problem with water dripping on the passenger side floor while using the AC. I have tried using air to clean out the AC drip tube. Recently my mechanic sprayed it out and no debris came out. There is a very minimal amount of water that comes out. Is there anything else I can check without ripping out tge entire dash? Also, not sure if it matters, but right before this happened I had tge blower fan replaced. Could that have anything to do with it?
