I have just register on your site and it is a great site at that. Very helpful for me as I am not that mechanically inclined and on a very low budget. I have a 1997 Chev S10 Pickup with 130,000km and is in pretty good shape with not real problems exept for the wiper blades. They will work for a while and then suddenly stop. I can hear the motor running but the blades are not moving. I will have to move the blades by hand and after a little it will grab whatever it is and they will start working again. The problem is slowly getting worse as it happens more often and is taking longer to grab again. Can you tell me what it is and if I can fix it myself or should I bring it in. Thanks.
