you may have already done this but did you check the fuse? the wires could have touched when you where installing it and blew the fuse. Or it could very well be the wiper switch. they are 80 bucks on rock auto. or get one from a salvage yard for 10. what I've found though, is that usually it's something simple. just retrace the wires and make sure nothing is chafing. or there is a small chance the new wiper motor is bad. I've seen it many times with electrical parts.
The 2002 Chevrolet trailblazer windshield wiper motor should be replaced, when the windshield wipers are skipping. The windshield wiper motor can be located in the engine compartment.
Your wiper arms that run from the wiper motor to the windshield wipers may be binding and need to be replaced
check the fuses and relays
More than likely the problem is the transmission that needs to be replaced
You have to remove the linkage from the wiper motor.
Weak battery or alternator output.
My wipers would only work on high. we replaced the signal lever which works the wipers too. i did get my mechanic to do it because it was'nt as easy as the parts store said it was. try replaceing the wiper pulse relay board under driver side dashboard
no
A loud, screeching noise from the wipers is probably because the wiper motor needs to be oiled. There should be a small screw on top of the wiper motor. Remove this screw and add a few drops of machine oil. Also oil the arms where the wipers are attached near the windshield.
ughh i have the same problem. you need to fix the windshield wiper motor
Assuming they did not work with the old wiper motor, check the fuse, check the switch.
could be a fuse, wiper switch ,wiper motor or wiring
