1998 Oldsmobile Aurora V8 Front Wheel Drive Automatic 105000 miles
HVAC fan has quit with no warning. During diagnostics, found fan operating (I jumped the terminals with a battery and the fan runs). I then turned attention to the Blower Motor Module. Ran diagnostics as defined in Mitchell manual and all evidence turns to the module is bad. Found a salvage unit and installed. At first fan still didn't work. Then I found by jiggling the 3 prong pigtail, the fan will run (this doesn't work on the original module). Acts like a loose connection, which it isn't.
My sense is that the salvage unit I bought also has a problem, but because it runs intermittently, the problem has to be with the module / pigtail. Looking for confirmation before I buy a new module.
have the same problem?
