The older Uplander likely had a different larger less efficient engine burning more fuel thus generating more heat with lower requirement emission systems that were able to function at a lower temperature so the thermostat opened at a lower temperature. default position only if previously set in the DIC, but these indicator lights also are not active either.The Start button merely serves the same functions as the ignition key in turning on the AUTO HVAC module setting and indicator lights in the seats.lack of heating on startup problem (proportionally worse in sub freezing weather) is because it takes a lot longer than 5 mins for the engine temp to reach 210F and the thermostat to open to circulate hot coolant to the radiator for cooling and heater core for warming.

the lights and control setting in the AUTO position and feedback modules just like the last memory position of the heated seats is not powered.the heated seats will be active in the max. In cold weather the remote starter will turn adjust the vent dampers and turn on the fan for heat in a default position. Can also lurch at really low speeds if the throttle is eased up right at the point where the tranny is negotiating a shift point where the tranny will continue to shift to a next higher or lower gear with a mismatch for the engine rpm.Ĭlick to expand.A remote start will turn on the heat.but, At high engine rpm a nice long smooth engagement is not necessarily a good thing. Even then on a fast acceleration, the harder the throttle the longer and higher rpm it will hold a gear and the harder the bump when it shifts - which is good because the servo is applying more hydraulic pressure so the band locks the planetary gearset more abruptly to prevent slippage. Should be no lurching on normal acceleration once the tranny has adapted to the owners driving techniques. No doubt all manufacturers and models experience the same problems.Īnd as far as a hard shift where it lurches forward a bit - better that than slippage. Of course if I park in the heated garage overnight like before an expected snowfall I'll get heat in a minute or two. we're no longer dealing with no emissions and 155F thermostats where heaters actually worked in really cold weather. Given sub zero temperatures and airflow sucking the heat out of the Al blocks and plastic tanks on the radiator you're no longer talking 5 minutes - you don't get heat until the engine reaches the 210F ideal operating temp for the emission controls - and if there is insufficent heat generated to keep the block at 210F to relaease coolant from the engine, you will get none.

Avalanches on AUTO, disable the fan until the heat is flowing through the heater core which can take the same 5 minutes or longer depending on outside temperature - only manual cold air defrost is available while you shiver in your seat, same lack of heat the way the Traverse operates.ĬAFE standards dictate that the engine gets the heat first before the passengers. GM never seems to keep to a constant system because seems every variant pi$$es someone off. Heated water is not available until after the thermostat opens when the engine reaches 210+F to route coolant to the heater core.

No warm air for at least the first 5 minutes even though the fan is operating., which you can manually turn off. Only problems with the HVAC is with the remote start which defaults to only cold air blowing until the start button is pushed - none of the electrical system is activated, not even the radio or to close the aero shutters to speed warmup of the radiator.
