I keep my Rear Sun Shade up most of the time. My baby looks cook and stay cool with it up. Until today, I lowerd it and everything went fine. When I tried to bring it up. the moter kept runing for about 5 seconds longer after it went all the way up. MY feeling that somthing is wrong. I have never had this problem before. Can someone help me with this? How do I go about troubleshooting this problem? How to I get access to the motor? HELP PLEASE>>>>>>>>
