Ok. I think I may have a short somewhere. When I have the radio on by itself it works fine. As soon as I hit the power button for the HVAC the radio flickers on and off by itself. Almost like the HVAC is drawing the power from the radio? The HVAC never gets a chance to turn on. It is a 2003 3.3L Caravan. Anyone have any suggestions?

 

Pulled the starter relay at the short went away. Heater/AC on and working. Put in a new one and symptom came back... Any Help/ Ideas???

 

bad ground somewhere.

 

Now the Driver side window does not work? Where should I start with the bad ground?
