Starting and window.
We believe its the ECU (i think thats what he said something computer) heating up for some reason. So when the engine is parked in the direct AZ sun is wont always start sometimes its laggy in and out and cuts off but only when its in the sun and it can be in the sun roughly 30 mins or longer and it will pull this... If i park in shade it starts just fine... If it helps its a 2001 chevy suburban K2500..... The other thing im so lost on we may be iver looking something as well but the front passanger window wont roll down... We hear it working it falls a little on its own but when we take the foor panel off everything looks fine and sounds fine and the window is on track.. Any ideas on either if these issues?
