Intermittent loss of power to heating/AC, GPS, clock. on 2004 Lexus RX330

Intermittent power loss for AC/Heat, GPS and clock. Also having problems with the side view mirrors and not sure if connected to first problem. Comes back on anytime it wants from 1 hr to 3 days. Cannot get it to the dealer in-time before it works again and they cannot fix what is not broke.

Theses are especially tough. The way I would approach this is to find the wiring that goes to the A/C/Heat, GPS and Clock and then inspect the connections and grounds for looseness or any unusual signs, as well as pulling on the wiring to see if I could duplicate the problem. How about going to a good Independent Shop that works on Lexus? I have worked in several Dealerships and not all of their Techs are the best in the field. http://repairpal.com/directory?address=80915&car_brand_names=Lexus

Have not figured out how to answer my problem with found solution which was - replace the battery. The battery was one year old and bad. Wal-Mart brought out their super tester and it said "replace battery". This replacement also fixed the side view mirror problem. Never had confidence a new battery could be bad, but it was a start. I drove from Colorado Spgs CO to Raleigh where I am now and did not like the obvious idea of driving back and the heating/AC going out. Thanks for your input.
