Rearview Mirror problems of the 2001 Mazda Tribute

The driver side mirror shakes so badly that the image in the mirror is so blurred you can not see anything. I took it back to the dealer, they replaced the mirror and it still did the samething. I complained a second time and they said there was nothing they could do since they already replaced it once. The second problem is that there is a lot of wind noise and a howling noise when driving on the freeway at 50 + mph. It gets so loud that it give me a headache. I told the dealer 3 times about this already. They changed out the window seals out 2 times and this has not solved the problem. What can be done to resolve these 2 defects? thanks.
