w140 Blower Fan runs on High
I just replaced the blower motor on my
93 300sd. Now the fan will suddenly run on the high speed, regardless of temperature. The high speed seems to be the speed and which it would run to work the defroster. However it is blowing cold air! It will run on high for a few minutes then suggendly drop to normal. This has been happening with increasing frequency since I installed the new blower motor. Now it wants to run high almost all the time. When I press 0, it cuts off. BTW, the outside sensor, per the diag test reads at 0F or 5F or 99F. HELP!
