Received car about year ago, 153000. All was good, then hvac controller would switch to Windows defrost and turn on heat, when a.c. was on. Then got worse, while adjusting hvac it would turn off with - - - in display.
Then got worse were finally hvac controller goes out, all Windows stop working, gas, boost temp gauges along with info display stops working. All or some or just one will stop working oh and door locks stop working. Intermittently. Drive to store,shop, get back in and another random selection is working or not working.
I do not no were to start. The passenger window does not work at all now. I can hear the motor run for a second then stop.
Instrument lights also intermittent and no HUD.

I'd start by having a look at your battery and connections. There are so many different problems here so begin with the basic stuff. There have been several reports in the past of corrosion under the rubber boots causing electrical problems. Disconnect both cables and have a really good look to make sure everything is clean (always negative first then attach negative last when reconnecting). What does the cluster say your voltage is when the car is running? How old is your battery? You likely have more than one problem.

Thanks for the info
I have plans to check the battery connections and clean good.
Another thing I forgot to mention,
in the early part of the failure when the passenger window would be used sometimes you would get a loud popping in the speakers. Not all the time just once in awhile.
