E problem is A PROBLEM!!!
To those of you that spent alot of time and $$$$ on this problem; the advice from Maserati today.............DON'T!!!! They adjusted the louver type door or damper which is usually the problem MOST of the time; mine is now working intermittently; but as DocJim pointed out , alot of money and no fix; they quoted me about 14-15 hours of labor to pull the dash; the tech's response; if you want it fixed, its gonna be expensive;I would leave it alone; as he quoted" that is just stupid money"....so I hope the reset on the damper works cause I am not gonna spend $2500 to see the Letter "e" leave my dash...dogdoc
