Most likely multiple problems going on here. 
Pretty common for the display screen on the climate control HVAC system. Here is a link to what most likely needs to be done to correct that:

Have you checked the fuses for the passenger door??? There are two. #30 and 31 in the passenger foot well fuse box. Problem might be as simple as a blown fuse.
If those fuses are OK then the passenger door window and door lock problem is most likely bad relays on the door control module. Here is a link to a thread about the door control module:

The driver and passenger DCM are identical so you might want to put the passenger DCM in the drivers door and see if the problem symptoms follow the DCM. If they do then you can either replace the relays yourself if you are into soldering or you can do a DCM exchange through one or more companies that provide that service. Here is one company that several Forum members have used:

There are others if you look on the big auction site......

Passenger lock window
I had the same issue on my 99. I reset the code, then physically pulled the switch assembly, cleaned the contacts and reassembled. No issues since. It's easy to at least check the connection and doesn't require any tools other than something to pry the switch up with.
