blower motor stop working?
 

I HAVE A 88 190e 2.3,
ON THE WAY TO WORK, A/C WORKING AIR BLOWING HIGH........COME TO A LONG LIGHT I TURNED THE BLOWER OFF, STARTED DRIVING AGAIN TURNED THE SWITCH BACK ON AND NOTHING HAPPENED. I CHECKED THE FUSES AND ALL ARE STILL KNEW. ALL OPINIONS WELCOME

I'm not familiar with this model, however it sounds like a blower regulator problem - I had a similar problem on my E55 (W210), it went short circuit and stayed on all the time, even with the ignition off!!

I hope that helps.

can tell me the location?

i had the similar problem on my w126, it was the climate control.
