'89 190E heater a/c fan does not come on
 

Hello, my '89 190E 2.6 heater a/c blower fan has stopped. I have replace the fan motor with a new Bosch original replacement and have tested both the fan switch and climate control units by putting in working ones from a '93 190E that I have where the parts appear to be identical. Where do I go next ? Is there a relay switch in the mix that I'm not aware of ? Thanks for any help. Padge

Everyone,... live and learn ! It turns out to be an external 25amp (blue) fuse located in a small black box with removable cap just prior to the main fuse box under the hood on the driver's side. Looks like the motor had stuck in some fashion and also caused the fuse to burn .
