Grand Marquis LSE ( Ultimate) V8

Suddenly I get this on and off of the blower every 3 to 4 days or more. Driving without AC is very uncomfortable in California. Driving without defroster in fog, rain etc is dangerous. Dealer calls it an electronic "glitch" and wants $1400 to replace the entire automatic ventilation control panel. Could it be a problem with a dirty electronic board or something to do with the sensor that monitors temperature for the automatic system?
