i would check if you have power to the motor from the switch
It might be tine for some new wipers on the car. You might also need to check the connection of it to see if that part needs to be replaced.
Generally, if the motor is working on windshield wipers, the problem is electrical. Check the fuses and the wiring to see if something needs replaced.
it may not be grounded. correctly. did you check it before you put it on? check with volt meter see if it is getting power. also it maybe that the rod to the wipers are jammed check them out.
Check the motor for the wipers.
Normally its a fuse. Check your owner's manual to find where the fuses are and which one is related to the wipers.
First check if your fuse , have gain bad , \if its alright , then check the wiper motor .
check the fuses and relays
If your windshield wipers still aren't working after replacing them and checking the fuses, you may need to check the electrical wiring. This is best done by a certified auto mechanic.
Assuming they did not work with the old wiper motor, check the fuse, check the switch.
If your windshield wipers are not working, you should check your owners manual. It could be a fuse or another easy fix.
I don't know specifically but there is almost never a large number of fuses in a car. It wouldn't hurt to check them all because any blown fuse would need to be replaced.
You might check the wiring of your speakers and check if they are working then check your CD player if its working properly.
