    It's not normal. Most problems people report with remote starters are installation errors, mostly interfering with car alarms and also "no-start" issues.

    Your car should warm up according to your settings.

    You do not specify which trim level Impala you own. The factory installed Remote Start System operates differently if you have an LS or an LT/LTZ/SS model.

    The base LS models do not have the external temperature display sensor. Remote Start on an LS requires the owner to set the climate control system to the settings they want before turning the car off. In the winter, this would mean turning on the heat before you park the car. In the summer, you would need to turn on the A/C before shutting the car off. Then, when you remote start the next time, the car will return to those settings. However, using Remote Start on an LS will never turn the rear window defroster on.

    LT/LTZ/SS models have the external temperature display sensor. The Remote Start system on these models checks the outside temperature and then sets the climate control system itself. In the winter, the remote start will turn the heat on if it detects the external temperature is at or below a certain level. It will also engage the rear window defroster. In the summer, the car will activate the air conditioner automatically if it detects the external temperature is at or above a certain level. The rear window defroster will not come on automatically when it is warm outside.

    Keep in mind that in all cases it will take at least 5 minutes for the car to truly cool down/warm up inside after remote starting. If you remote start and then jump right in, it will not feel like the car is using any specific cooling or heating settings.

    Thanks ryster---I was under the impression, reading his original question, that he DID pre-set the temp or AC and still got nothing, so that's why I thought something was amiss. But now that I think of it, you may be right. If he pre-sets, it really HAS to work once the car starts. Maybe he's not waiting long enough?

    Hi Mr. Shiftright, no problem. With there being two different systems it is hard to tell what the case may be.

    If the car is an LT/LTZ/SS, there is the possibilty that the external temperature sensor is faulty, and as a result the car cannot read the external temperaure when the car is started remotely. Therefore it does not know whether to turn the heat or A/C on, and simply blows outside temperature air.

    The easiest way to tell if that is the case would be to look at the external temperature readout in the driver information center. If it reads "---", then that is most likely the problem.

    Assuming everything is functioning correctly, the car will need several minutes to fully warm or cool.
