I was driving home today and it was raining enough to need wipers on. All of a sudden the driver side wiper made a little kind of pop noise and it hung in the upright position. The other one was still going fine. When I finally got home and checked it, it would move manually and you could feel a slight vibration in the arm like it wanted to move but couldn't. I tried tightening the nut under the cap but it did not seem loose.
The problem is in the mechanics of the wiper at the firewall (inside undr the vents) the connector to the wiper arm has come loose from the controlling arm (laymen's terms) you'll need to access the workings and re-connect the arm..the access panel is normally held on with a few screws.....make sure the repair will stay connected and is not worn out.. good luck to you....it is about an hour fix...
I have a 04 plate c. Max my driver side wiper works fine but passenger side stopped working what could be causing this

Yes the spring in the arm is weak, replace the arm and your problem will be solved.
SOURCE: Front windshiled wipers not working
The only thing left to try, other than replace the arms is, take those nuts right off & remove the arms. Take a small wire brush, or whatever you can find that will work and clean the splines on the pivots, and inside arms as much as possible, re-attach arms & tighten. If the metal is stripped away too much inside arm, they may have to be replaced, either from a wreckers, or new. There are some compounds out there that they say work, to add metal, but in my experience, they weren't all they were cracked up to be.

These are a tight fit...Spray a little penetrating lubricant onto it and let it sit for about 20 minutes. You will notice there are splines that match up from the drive unit to the base of the wiper arm...sometimes these can get a little corroded and becasue of the relative surface area it makes them a real pain to get off. You may need to just pry against it gently with a flat head scredriver after you spray on the lubricant. Pray at it from all different sides of the base so that it doesn't bind up and get crooked.
Hope this helps! Good Luck!
SOURCE: Wiper arm/s are slipping on the post.
Only fix is to go to a local junkyard and get the same motor/shaft assmbly...if you can't do it yourself...check with the junkyard for references.
Good Luck.

If the armature to the wiper motor is not broke, then tighen the nut.

Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
High Speed Operation
When the wiper switch is in the high speed position, ground is applied through the windshield wiper switch high signal circuit to the body control module (BCM) indicating the wiper high speed request. In response to this signal, the BCM then energizes the wiper PCB relay, as stated above, and the wiper high PCB relay by applying ground through the control circuit to the coil side of the relay. With the wiper high relay energized and its switch contacts closed to the high speed control circuit of the wiper motor, the motor will operate at high speed.
Wiper motor high speed operation and the wiper high speed PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.

You could Have a switch problem , BCM problem ,PCB relay problem , the pcb relays are non serviceable an the whole under hood fuse box would need to be replaced . Malfunctioning motor bad ground some where etc.....
