Hey george1073. FYI - to post a new thread just click the 'New Thread' button at the top of the page under the car category you want. For example if you want to post for Century get into the Century page to do this. This button will not appear once you are into a thread on that particular page, only under the vehicle 'home' page. Also, as far as your blower motor...it sounds to me like you need a new one. Whining and squealing usually indicate that due to wear internally. You can test the switch and resistor to check those 'less expensive' avenues first, but you didn't mention only having a few(or one) speeds as a resistor will commonly cause. However you may have a switch that's on it's way out. In my opinion, it sounds like you may have a bearing or brushes going bad in the motor itself and that's what's causing the noise. Give it a few taps w/ a rubber mallet(if you can get to it) when it's acting up to see if it quiets it down, or helps it speed back up. If so, you need a motor. I had a very similar issue w/ my Tahoe a while back. The blower worked fine most of the time but sometimes it simply wouldn't turn on and sometimes after it was running for a while it would 'wind itself down'. By 'tapping' it w/ the mallet(as w/ a starter that won't turn), I got it to wind back up, but in the end I did replace the motor because it became a PItA. I hope this helps. Let me know what you find. M
