general problems of the 2014 Dodge Caravan

I have 2 complaints. One is that the driver's side window doesn't always work. It works sometimes and other times does not. It's as if there might be a loose connection or something. The second is that there is a constant ticking noise in the engine. There is no sign of oil leak. I check it regularly. My thought is perhaps a valve or a belt. But I'm not sure. The vehicle still drives. It has not broken down.

Check engine light came on oil pressure sensor went bad.

The passenger doors no longer open with the automatic system. The passenger windows in the back do not work any longer . The door locks do not lock by the remote or by the door button. I have to manually push them down. And occasionally the all the lights just light up and begin flashing and dinging while driving and just sitting in park. The electrical system is bad!!!. I have had to replace one fuse in the drivers motorized seat. This has been on ongoing problem since spring of 2017.
