My 1998 C230 blower had a problem because it remained on at full force after washing the car. Removed the fuse and stopped the blower. I did not have time to correct this immediately, so I toggled using the fuse to use the blower when needed. It has NOW failed completely. I have also got an E320 with a failed blower (looking to kill 2 birds with this same stone). I am new to forums and would appreciate any direction to info sources and/or direct help. (fyi - have fixed C230 oxygen sensor and E320 rear window power regulator and wheel spead sensors, I am getting hooked on web enabled Mercedes repair work - so thanks ahead of time for adding the power of forums)
