How comfy are you with car and auto parts. The S500 ('97) is not for novices. If you have no idea where to start looking for the blower it is unlikely you will have any idea repairing the blower or it's parts even if you identify it. Get a mechanic!
If you have a voltmeter you just need to check the voltages when the blower runs to see if the regulator is working. You will need to unwire the blower a little, but it's rather simple. add a comment
