2002 Jeep Cherokee

We recently had to replace the passenger door mirror. Since then, controls such as the windows and door locks would not work while the passenger door is open. Last night multiple functions stopped working. Here is a list:
Windows do not go up or down
Air conditioning is not blowing cold air
Steering wheel radio controls do not work
The alarm won't set
Automatic seat setting don't work
Outside temp. function doesn't work
Miles per gallon function doesn't work

Any ideas? Anyone ever have a problem like this with their Jeep.
