The dealership did a diagnostic and told me i need a blower regulator and a new acc pushbutton unit. His price for parts & 5 hrs labor is $1460.21. I know that a rebuilt acc runs about $275 and is "plug and play". Looking at the repair manual, the replacement instructions for the blower regulator are pretty straightforward so i think i can do it myself. I see a regulator offered on ebay from a 92 300E and the part number is bosch #124 820 27 10. Does anyone know if this is the correct part number for me? Also see a 87 SDL regulator is available. Would this fit??
