My car is an 87 and I don't have any scenes of highway and city on any of my controls. Time to pull out the owners manual perhaps. |

I agree, Hans. My 308 GTB had a similar problem on the passenger's side. The cable was adjusted and now the valve closes audibly and properly. |

The control valves are cable operated (at least they are on my old timer). You might try fiddling with cable adjustment before ordering new valves. (If, indeed, the valves are the problem!) |

You don't mention what year your 328 is, but if it is an earlier one, you have to turn the control down when on the highway or the condenser coils frost up and you went get cold air. There is a picture of a city and a rural scene on the control, same as 308 QV's. Later 328's changed (I don't know exactly when).

If it is heat from the heater cores, what is the fix? Replace the control valves? |

I'd second the heater core idea. Alternator draw at higher rpm shouldn't vary enough to make a difference. Several others have reported leaky heater control valves. If you can, feel the heater hoses to see if hot water is flowing. |

Could be that you are getting some Pirate heated air forced from the heater cores that is blending in with the cooled air from the A/C at high speeds. |

Alternator problem?? At higher RPMs, the draw is higher and the compressor kicks off. how's that for guess? Have you driven at night with the lights on plus the AC? |

I made a road trip in my car last weekend and nearly cooked. The car has a new compressor, installed in March. It seemed whenever I drove the car about 80mph, the air quit blowing cold. If I slowed to 55, or got down to in-town speeds, everything cooled right off. By the time I reached my destination, 75 miles later, I was roasting. Today at lunch I spent nearly the whole hour driving in city traffic and was perfectly comfortable in 90 degree weather. This after the car had baked in the sun all morning. What gives? |
