Re: [MBZ] '84 300D fan speed
Could be worn brushes. not sure about how the speed control works in these, but no resistance would be full speed (or an open circuit). Check the blower resistors out; they are probably mounted near the front of the inside of the passenger fender. Also check the connector. -- John W Reames jream...@verizon.net Home: +14106646986 Mobile: +14437915905 On Dec 16, 2011, at 12:55, glenn brown wrote: I wonder if anyone on the list has experienced something similar and might be able to suggest a cure. The fan speeds, as governed by the upper(6th speed) and lower(1st speed) have for about the last year or so been providing what feels like possibly the 3rd speed(upper push button) and 1st speed(lower push button). Also, the fan speed when the defrost push button is depressed in my '84 300D is similar to that obtained when the upper push button is depressed. Note: This oddity does not appear to be related to the ACC PBU, as the ACC PBU from my '85 300TD, which operates fine in the TD, provides the same low fan speed operation when installed in my '84 300D.
