Question about 1990 Mercedes-Benz 190
I changed to blower motor but it still doesn't work. I can spin the blower motor with my finger but it turns slow. When I put it all back together it doesn't spin at all when I turn it on

Probably two separate problems.
For the blower motor, it may be that the bearings are getting old and so the motor is getting harder to turn and overheating. A way to check is to take the motor out (it will be tucked in behind the glovebox. Pour a tablespoon of motor oil into the vents next to the shaft and work it back and forth to loosen it up. Then put the motor back in and try it. If I'm right, the motor will work normally again. However, this is only temporary--once the oil gets worn off the bearings in a while it will start quitting again. You should order a replacement before it blows your resistor block or (in the worst case) starts a fire. You can get them online, like from autopartswarehouse.com

under the hood between fire wall and engine underneath the wiper motor. If its not working replace the strip fuse by the driver side strut mount first. Its in a tootsie roll sized plastic case.
