190e Fan blower slide switch

Hi
I'm brand new to the forum. I have a 92 190E 2.6. Last night my fan blower motor switch just STOPPED going to last two positions, to the right. It works fine in the low and medium positions. I removed the button control box and the switch, cleaned all the contacts for all connectors and looked for anything obvious in the switch itself. Nothing seems jammed but the darn thing just won't go to the last two positions. Does anyone have any ideas?
Thank you

I have the opposite problem...doesn't work on the low setting

I just adjust the temp on the higher blower speeds to compensate.

Im guessing the contacts are just worn out on mine after 209K miles....no first hand research but it looks like you might have to take part of the dash off to replace it...

Thanks again...it was the just the switch. Strange though, that it was fine one minute and then just would not switch to the next position. Already installed a new used one and works fine.
