Windshield Wiper Electronic Problems
I have an 09 Ram, and as of about 5k miles ago I've had a problem with my wipers where they are stuck on in the first non-intermittent setting no matter what I have my wipers set on. I have had to remove my fuse to keep them from staying on. I noticed this one time at around the first 10k miles but never had the problem again. Now it will stay on about 90% of the time the fuse is in, so my only solution is to have the fuse out and manually put it in if it starts raining.
I know there was a recall for this awhile back but my manufacturing date is 2 months past the date for the acceptable recall. Any solutions or ideas? I've got about 47k miles on it now.

Mine did just the opposite, if I shut the truck off with the wipers on intermittent 90% of the time when I restart it the wipers were dead unless I turned the switch all the way off and turned it back on again.
A while back I disconnected the battery for 20 minutes since my radio was freaking out and that seemed to have fixed both the radio and the wipers so who knows. Dealer said they couldnt find a problem with it when it was screwing up all the time for both the wipers and the radio..

Not with 47K on the clock. Just drive train left unless and extended was purchased.
The vehicle operator initiates all wiper and washer system functions with the control **** (1) on the end of the control stalk (2) of the multi-function switch that extends from the left side of the steering column, just below the steering wheel. Rotating the control **** on the end of the control stalk, selects the OFF, DELAY, LOW, or HIGH wiper system operating modes. In the DELAY mode, the control **** also allows the vehicle operator to select from one of five intermittent wipe delay intervals.
Depressing the control **** towards the steering column to the first detent actuates a momentary switch and selects the MIST mode, which cycles the wiper blades for as long as the switch is held closed then completes the current cycle and parks the blades at the base of the windshield after the switch is released. Depressing the control **** to the second detent actuates the momentary washer system switch, which selects the WASH or WIPE-AFTER-WASH modes depending upon when and how long the switch is held closed.
The multi-function switch provides hard wired analog and resistor multiplexed inputs to the Steering Control Module (SCM) internal to the multi-function switch housing for all of the wiper and washer system functions. The SCM then sends electronic wiper and washer switch status messages to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) over a Local Interface Network (LIN) data bus. The EMIC responds to the SCM inputs by sending electronic wiper and washer system request messages to the Totally Integrated Power Module (TIPM) over the Controller Area Network (CAN) data bus requesting the appropriate wiper and washer system operating modes.
Wiper and washer system operation are completely controlled by the SCM, EMIC and TIPM logic circuits, and that logic will only allow these systems to operate when the ignition switch is in the ACCESSORY or ON positions. The TIPM uses intelligent, high current, self-protected high side switches to control wiper system operation by energizing or de-energizing the wiper motor low and high speed brushes. The TIPM uses a high side driver to control the operation of the washer pump/motor unit. The multi-function switch circuitry receives battery current and a clean ground output from the SCM, then provides analog and resistor multiplexed inputs to the SCM to indicate the selected wiper and washer system mode.
The hard wired circuits and components of the wiper and washer system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the wiper and washer system or the electronic controls or communication between other modules and devices that provide some features of the wiper and washer system. The most reliable, efficient, and accurate means to diagnose the wiper and washer system or the electronic controls and communication related to wiper and washer system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
Unless the switch is stuck or something else obvious a trip to the dealer is most likely in order.
