I am having trouble finding whats is wrong with my front windshield wipers. I check the fuze in the car under the driver side dash and it looks fine. Is there a wiper relay that i should be checking or do the wiper motors go out on these often? any insite would be very much appriciated.

Also my back wiper and sprayer works great. but i can not hear anything from my front ones at all. the spray pump dont work either. Is there a fuse that im missing some where?

I dont know if my wiper motor is bad or i have a relay out. I have looked every where. I find it very weird that my back one work just fine but my front one nothing works. not even my spray motor will work. Has anyone out there had this problem?

Leave the wiper switch on and wiggle the fuse around, could just be loose.

You can apply 12 volts directly to the motor. If the windshield wipers move then its not the motor it's the switch/relay.

Ok is there a special way to pull the wiper arms off. I cannot seem to get the off and i dont want to pry them on in fear of breaking the black plastic.

You should be able to remove the plastic cowl pieces (about 4 clips/plastic screws) and then take the wiper assemblies apart

Ok did all that and started to check for power and im not getting power to the wiper fuse. What would u cause that it all the sudden did this? I believe that is why they are not working but dont know what to do to fix that.

Check out the wiring diagrams in the "Everything you need to know about Z32's" post. I'm not sure how the wiper system works exactly but I do know the power should go to the fuse first and then to the motor. So if you aren't getting power to the fuse then something before that is messed up. Not sure if the switch/relay is before the fuse. Maybe a loose connector somewhere? You could just get a new fuse anyway and check that first.
