Driving on humid day, closed windows and turned on A/C. controller failed to close defroster vents, causing window to quickly fog up, restricting forward vision. Previously had same problem on 2006 Grand Marquis which I had repaired by Ford dealer. Took 2011 to dealer, got repair estimate of $900, as dashboard must be removed to get to failing part. Am told problem is vacuum leak in controller component. Although associated with A/C, which generally is not considered a safety issue, the controller failure does result in a safety issue, and in my opinion should be subject to recall.

My 2011 Mercury Grand Marquis ultimate edition, was very great however it caught on fire due to the malfunction of the windshield wipers...they would come on automatically while I was driving, my windshield wiper switch would be on the off position... and the wipers only worked on a high speed seeing none of the other speeds worked...prime example I would warm up the car for 10 min...because its cold outside then I would drive, all of a sudden minutes later, my windshield wiper turn on by itself in a high speed position, I turned the wipers on so I can see if turning off would help it doesn't so clearly it has a mind of its own...as if a ghost was in it...I googled the problem..cleary there are other models of the same and different year numbers that have the same problem...they say its either the wipers motor a relay or the whole left, right indicated switch which the windshield wipers works off of...long story short my car caught on fire the morning of Nov.21, 2018 a day before thanksgiving in my driveway which could have set my car on fire..had to call the fire department at 1:45am in the morning. Due to an electrical issue the car had..it looked like a movie with the car on fire. Because clearly if the car is parked and the windshield wipers motor is still trying to move with no power to the car...I loved that car so much..it almost caught my house on fire...could have exploded and put my family at risk.which it did. As much as I love Ford, Lincoln, Mercury I am just saddens and devastated that the car I wanted loved and bought or shall I say financed is totalled buy an electrical fire that burned the inside all up in my car and engine is burned out....and the fire when I was woken up to hear this when I called 911 and was looking outside the fire that I seen started from that driver side front windshield with fire coming from the motor of the wiper onto hood

I was driving on the highway I smelled a weird smell coming from the passenger side when I turned to look towards the direction of the passenger side front door it was smoking so I immediately pulled over to the side of highway as I was doing so the passenger front door caught fire. I finished pulling over turned the car off got out and pulled my fire extinguisher out trunk went to the back passenger side door in order to put the flames out in the front passenger side door. Truly upset and scared me. Can't understand why it happened. I did take the door panel off what's I figured it safe to and try to find where and how the fire started and as well to make sure the fire was completely extinguished. All I could see was some exposed wires that were partially covered in blue tape. I was very leary to drive on home but did so cautiously with windows down. Grateful I made it home and my family wasn't in the car. Took pictures they will be attached.
