On the drive back from Pahrump (Ron Fellows) last night I was quietly cruising in the mid 70s (on cruise control) and noticed two peculiar things happening to RedHot: She seemed to have a very slight surge on and off and the temperature was getting pretty cold in the cabin (outside temps were in the 90s). I focused on the rpms and noted a slight quick run up and drop back of about 100 rpms even though the actual speed seemed to be remaining fairly constant. At the time I guessed it might be related the the AC compressor cutting in and out. Took the AC system setting off "auto" and that seemed to smooth it out, but the temp still seemed to be too cold respective to where it was set. Today when I checked our TSB/Recall section I saw the "HVAC Temperature Fluctuations" write-up and that seemed to be what I was experiencing (even though the write up did not mention the variations in the rpms, but that intuitively makes sense to me to be related). When I get a chance I will schedule a service for her and bring in the HVAC Temperature Fluctuations write-up. Let you know what they find.
Update: Got an appointment with my dealer tomorrow so I should know what they find.
