We have a 2003 Toyota 4Runner with the V8.
The temperature here has been below -20c many times so far this year. About a week ago my wife noticed that her 4runner is not warm inside when using her remote start. I drove this weekend and the remote starter works fine, engine temperature rises to normal running levels but the heater will not blow warm air until we enter the vehicle and step on the gas peddle. Once we do this the heat works just fine until the next time we cold start the vehicle. We have since topped up the antifreeze and this has not solved the problem.
Any assistance here would be appreciated.
