How to Replace a Wiper Motor in a Blazerby Alibaster Smith
Over time, the wiper motor in a Chevy Blazer may burn out from normal use, or it may suffer an electrical short. On the Blazer, the motor typically just burns out from use. Replacement motors can be purchased from the Chevy division of General Motors or from most auto parts stores. Know the year of your Blazer so that you get the correct motor.
Disconnect the negative terminal on the battery. Loosen the retaining nut on the negative cable clamp and lift the clamp off the negative terminal.
Remove the screws on the cowl of the Blazer at the base of the windshield on the outside of the vehicle. Some model years use several bolts instead of screws to hold the cowl in place. Remove the cowl.
Remove the electrical connector through the cowl opening that is connected to the Blazer's wiper motor.
Open the hood and remove the mounting bolts on the wiper motor. The motor is secured to the firewall.
Pull the motor off the firewall and install the new wiper motor. Installation is the reverse of removal.
