Driver's side windshield wiper arm won't work. 2007 Chrysler 300?
So recently my driver's side windshield wiper stopped working. The arm won't move. The passenger side one is working fine and I can see that the drivers side one moves a little but it doesn't even clear the wiper cowl/shroud. I thought it might be the motor but when if it was the motor, wouldn't both arms not work?
Any suggestions would be appreciated. With all the rain this week and snow yesterday and today i really can't afford to not have my drivers side wiper not working.

You are correct that the issue is not with the motor because there is only one motor and if it was not working then neither wiper arm would work.
There is probably something wrong with the front wiper module, which consists of the following major components:
Crank Arm - The wiper motor crank arm is a stamped steel unit with an internally splined hole on the driven end that is secured to the wiper motor output shaft with a nut, and a long ball stud secured to the drive end to accept the wiper linkage.
Linkage - The two wiper linkage members are each constructed of stamped steel. A driver side drive link with a plastic socket-type bushing in the left end, and a plastic sleeve-type bushing in the right end. The socket bushing is snap-fit over the pivot ball stud on the left pivot lever arm, while the sleeve bushing is fit over the longer pivot stud on the wiper motor crank arm. The passenger side drive link has a plastic socket-type bushing on each end. One end of this drive link is snap-fit over the ball stud on the right pivot lever arm, while the other end is snap-fit over the top of the driver side drive link on the ball stud of the wiper motor crank arm.
Motor - The wiper motor is secured on the underside of the module bracket near the center with three screws. The wiper motor output shaft passes through a hole in the module bracket, where a nut secures the wiper motor crank arm to the motor output shaft. The two-speed permanent magnet wiper motor features an integral transmission, an internal park switch, and an internal Positive Temperature Coefficient (PTC) circuit breaker.
Pivots - This module features two pivots. The two wiper pivot shafts have lever arms with ball studs at their base to accept the wiper linkage. The upper end of all three pivot shafts has a threaded stud with a tapered and serrated area just below the threads to accept the left wiper arm or the right wiper arm links.
The front wiper module cannot be adjusted or repaired. The front wiper motor is available for separate service replacement. If any other component of the module is inoperative or damaged, the entire front wiper module unit must be replaced.
The front wiper module is secured with screws through two rubber grommet-type insulators to the cowl plenum panel. The module is located in the rear of the engine compartment where it is concealed beneath the molded plastic cowl plenum grille panel. The ends of the pivot shafts protruding through openings in the cowl plenum cover/grille panel are the only visible components of the wiper module.

The wiper motor bellcrank drives a pair of rods that connect to splined pivots that the wiper arms attach to. The rods from the motor connect to the pivots with a ball and socket arrangement. The plastic socket connector may have popped off or broken or the wiper arm itself may be stripped where it attaches to the pivot splined shaft.
You would have to remove the wiper arm from the splined shaft and see if it is OK or check the ball and socket of the rods that come from the motor which requires removing both wiper arms and the shrouding or cowl grille below them to get access to the wiper motor linkages. Some wiper arms are held to the splined shaft with a nut and some are held in place by a clip at the bottom of the arm....not sure what style you have. If you have the clip type , you have to pry the clip sideways in order to wiggle the arm off the shaft. If you can manually move the wiper arm when the wipers are off but the rod from the motor does not move or is still connected to the splined pivot shaft, I'd suspect a stripped spline. Salvage yards sell the wiper arms and socket parts or buy from a dealer.

You have whats called a wiper module!!!!
The front wiper module is secured with screws through two rubber grommet-type insulators to the cowl plenum panel.
The module is located in the rear of the engine compartment where it is concealed beneath the molded plastic cowl plenum grille panel.
You can try calling the dealer to see if they will have the needed bushing and or rubber grommets but if not then you will need to buy the complete unit.

There is a regulator connecting both arms together. Ether one of the ball joints has popped off or the wiper arm at the pivot has stripped/come loose.
