Hi, We have had this Excel since new with very few real issues. The one that is causing me drama is the windows are becoming difficult to wind down past about half way. I anticipate that the regulator may need some work, meaning I need to remove the door trim to gain access. I have been to the Hyundai tech site and printed the exploded view of the door assembly and instructions for adjustment of the regulator. The winder is meant to have a clip retaining it which can be removed with a screwdriver. However I have tried in vain to do this and have had no success at all. I am not sure that the instructions are correct, can someone please shed some light on this for me. Thanks and cheers, Ray
