All at once we have no blinkers, no high beams, cannot use windshield washer fluid, only one speed for windshield wipers. Random lights are coming and going on the dash. Help!

More then likely the central electronic module is the issue as these components all run through this module. I would suggest going to this and just testing the voltage coming out on one of the components and I suspect you will not have any voltage.

Here is a guide that will help with this:

Below is the diagram and the process if it proves out to be the ECM. Please run through this material and let us know if you have questions. Thanks
