Tanya! Bonnie! Please don't shout at us!! Now...

1. Replace the camshaft position sensors (both of them). Use only OEM or Hitachi (OEM manufacturer) sensors.
2. Need more info on the dash lights. Which ones, and provide the entire list of diagnostic codes for folks here to use to help you.
3. Radiator fan MAY be the motor/clutch assembly if one is working and the other not. It's a two stage system. If it's not hot outside and you are not racing around and the AC isn't on, it may only be running on one fan because the demand isn't there to require two fans to keep temps in line.
4. The P0462 fuel level sensor alert may or may not be the sensor. Could be a number of things. There are lots of threads on the forum for this code. Hunt them down and read all about it.
5. Since you don't pay tolls or get drive-through McDonalds through the passenger window, that's your lowest priority. It's probably the window motor needs replaced, but sometimes it's the switch in the passenger door, but it could also be the master switch in the driver door. YouTube has videos for switch and motor replacement.

Also, this sub forum isn't the place to post questions. It's the place to post your intro to the community. Tell us a little about yourselves. With good fortune, a moderator will move this thread to a more appropriate sub forum where perhaps more folks will see it.

 

We do force people here for their first post. Camshaft sensors first is always a good place to start.
