Do a reset on the powertrain control module by disconnecting the negative and positive battery post terminals for half an hour. It will reset the instrument clusters.
Note: before reconnecting the battery terminals to their posts, touching the negative and positive terminals together for a minute to have a complete reset to the powertrain control module.

Contact the local delaership for the recall details and specific items covered, or not.

Several possibilities; leaking rear window gasket or seal, leaking side window weatherstrip or seal, leaking front windshield seal, leaking 3rd brake light seal or gasket. Yes, this seems to be a known / common problem on the Ram rear window seal.

Usually, the window regulator is replaced as an assembly - to include the motor. Sometimes, the motor is available separately. In this case, since you can hear the motor - then I would suspect the drive gear is worn, the regulator is binding / worn out, or the regualtor tape is faulty.
Check the many different on-line auto parts sources; such as - www.autopartswarehouse.com, www.partsgeek.com, www.rockauto.com, and www.1aauto.com for the replacement parts. For example, they (1aauto.com) list the window regulator tape from around $25.00 for your vehicle.

well why does it need replaced? Is it broken as in no light Or broken as in broke as in the whole piece?
you may have to buy the whole unit.. but you may be able to find one used in a junk yard or scrap yard or on criagslist...

you have to replace the mirror

You could try pulling it out again and try to fix it correctly. or if you are not sure you will do it right ask for professional help from your mechanic. because even if you have to purchase a new one , you still have to remove the one not fixed correctly.

Plug in the air bag connection with the battery cables disconnected. While they are disconnected, touch the two terminal ends together for a minute to discharge any residual current stored in all modules. As far as programming, it is not required but it will require a code reader that can read and erase Chrysler air bag codes, which will then clear the light. I assume that you are aware that unless the code reader says it can read air bag codes, it will not read anything but engine codes.

It is called a blower motor resistor for future reference. If you ask for a "heater fan speed control switch" they will sell you a fan switch which is the knob that changes the speeds on the dash. The blower resistor is accessible after removing the right side lower insulation / sound panel, just above where your passenger's feet would be.
