Our 1988 W124 300TE A/C Blower fan is not-working when the car is running. If I turn-off the engine and put the ignition switch in position 2 WITHOUT starting the car, the blower fan works in HIGH, AUTO, and LOW, but once started the blower fan does *not* work.

All fuses checked OK and replaced 2-years ago. What get's me is it works when the engine is not running . . .

Any ideas?

Thanks,
