My 2000 Mercury Grand Marquis always blow hot air out. What is the problem

Asked by wreggie Jan 31, 2015 at 07:02 PM about the 2000 Mercury Grand Marquis LS

Question type: Maintenance & Repair

My 2000 Mercury Grand Marquis had a clicking sound with the switch on of heater
blowing, AC or vent.... at beginning time and then it quit but now I only get really hot air
blowing out.  Even when I put it on A/C, Max A/C, Vent, etc.  Also, changing the
temperature setting doesn't change the workings.  It is just always really hot air.  The only
way to stop it is turn it all off.  What is the problem?
