Rear Window Wiper Washer Motor problems of the 2008 Mazda MAZDA3

Windshield wipers failed again. Refer to original complaint # 10343804 14jul10 wiper motor failed, $337. 00 second complaint # 10356107 17sep10 high speed operation of wipers failed. This second complaint was resolved on 01oct10, $880. 00. This time the cause was a bad relay on what they (dealer) called a fuse block assy. Relay is not replaceable you have to replace the entire assembly! I have the old fuse block assembly although they bent some of the connector pins on it! funny I can not find any fuses on it! I no longer feel safe driving this vehicle what with steering complaints, excessive rear tire inner edge wear I have seen on your web sight among other things and the fog light lenses cracking on both sides (app $125. 00 ea to get a inspection sticker)on my car. My wind shield had to be replaced after a crack developed from a very minor impact that left a pit you would not have been able to see if it were not for the crack radatinf from it in two directions, I never heard the impact. But wipers failing on a 2 year old car is unacceptable! loss of visibility is instant in heavy rain!.
