Mine has the "moorse code" noise as well, it goes away when I turn recirculation on. I took the cowl off the lower part of the windshield on the outside and the intake for the hvac system on the passenger side, when this is open (recirculation off) it makes a terrible noise at 73+ mph, as soon as I turn recirculation on it goes away. The only way to get to this unit is to completely remove the dash, it's not accessable from outside the cab in any way. My truck also has a squeeky center armrest and it leaks engine oil and transmission fluid (even after they replaced the front main seal, timing cover gasket, and driveshaft). Are there any lemon law lawyers that would like to help me with this mess?
