Road trip results
Moved the car,(300sdl) from Pa to Ga. 786 miles in a little over 12 hours door to door. Average mpg 27.6.
Air conditioning question. It works,kind of, as long as I am rolling down the highway. Seeing that I don't have the aux fan I don't attempt to use it in town. For the first part of the trip I kept the car comfortable with outside temps pushing 93f. The temp gauge got to 100 on one long hill on I 81. That's when I cut the air off until I topped the hill. Back on gong down the other side, no issues . After I stopped for fuel the first time no more ac. I checked fuses all good. Chalked it up to a gremlin.last hour of trip the ac came back on with the Econ button pushed. any ideas? Because of the bad pods in the dash it comes out the defrost and the center vents. That is also on the list.

The symptom points to an erratic CCU. It's a common failure..........a/c on in the economy mode. Either take another shot with a used unit or get a rebuild. |

Thanks for the info. Will start looking for parts.
Does the mileage seem about right to you? I was cruising right at 75 or better the whole way.

I would manage 30 only under conditions of no a/c and nothing faster than 67 mph...........frequently less due to traffic conditions. Most surprisingly, the 617 just did 30 mpg, yet again, WITH a/c...........in mixed city/highway (20/80). |
