About a year ago windshield wipers stopped working properly. Intermittent and slow speed do not work and fast speed works slower than normal, but only back and forth three or four times before stopping altogether. Must turn switch off and back on before wipers work again. I have changed motor and switch twice each and voltage regulator with no improvement.

Check the ground going to the body from battery and engine to body. Also, check switch to see if properly grounded. Also, check the three things I have pointed out in diagram. You may have a bad interval governor.

My windows will not roll down, windshield wipers do not work and the radio does not work. I checked all the fuses and relays do not know what else to do? I am not mechanically inclined so this is become a growing headache. I believe it to be a combined issue.

Re check all fuses with a test light. You have one bad somewhere.

Test light cannot check an alternator. You need to have it load tested as it sounds the voltage regulator is not working. It should keep the voltage at 14.5 volts with a load or not.

The driver side wiper sprayer does not work on my truck. The passenger side works fine. How difficult is it to repair/replace the wiper sprayer system?

It is probably just a plugged up spray nozzle. Get a fine piece of wire and clean it out.

You need to have the wiper control module the interval governor checked and tested located at right of steering column.

V8 four wheel drive automatic 82,000 miles

My wipers stopped working. I replaced motor and wipers work, but gauge does not. Speedometer is jumping all over and the odometer is flashing on and off. I put in new wiper motor and still the same problem.
