The windshield wiper/washer switch signal circuits are inputs to the body control module (BCM) and the BCM controls wiper motor low speed operation, washer pump and high speed operation. The windshield wiper/washer switch is provided a low reference from the BCM and each of the switch signal circuits is supplied 12 volts through a resistor and Two trucks I purchased new. 93 and 94 Silverado. Same problem with windshield wiper as described in other reports. I found my problem to be a combination of bad (loose connection) at the plug on the wiring harness that plugs into the wiper motor housing as well as bad solder connections inside the motor housing from the female plug to the wiper motor control board. Slow wipers - posted in Spec Miata Garage: Newbie with a new-for-me 92 with maybe a dumb question: my windshield wipers run at one speed only---very slow--no matter where the stalk is. Cleaning electrical contacts did not change anything. Given the rain weve been having in the NE, seems like a repair is needed. Ideas appreciated as to where to start looking, schematic not too useful. . The first step in fixing only one windshield wiper working in the Mazda BT-50 is to check the pivot nut. A pivot nut keeps each wiper arm connected to its respective wiper transmission stem. They’re big (usually 15mm+). A loose wiper pivot nut can keep a wiper blade from moving if it has worked itself loose. Verify the nut is still tight. Take a look at the wiring first. 1. Test your CX-3’s Wiper Motor Fuse. If the fuse is good, both ends will light up a test light with the key on. Before replacing the wiper motor, check your CX-3’s fuse box and determine whether or not the fuse has blown.

The vehicle had 29,634 miles on it at the time of repair. The issue is identical to that described in “ssm 49264: 2019-2020 – climate Inspect the Wiring Harness. If your MX-5’s wiper fuse checks out, inspect the wiring harness to the wiper motor. Use a voltage tester or test light and connect it to where the harness connects to the wiper motor first. If there is no voltage going to the car’s motor (and the fuse was good), trace the harness back until you find the short/open. put your multimeter across the fuse and ground (ignition on) - see voltage ? good, no ? figure out why. find the wiper motor, and the wires going to it. this service manual is for a NB, but I suspect the motor testing details (and the motors) are the same. No volts there ? something between the fuse and the motor is broken so: check the switch. wIj0.
