2009 hyundai elantra heating issues

Asked by D1999 Jan 07, 2018 at 08:14 AM about the 2009 Hyundai Elantra GL FWD

Question type: Maintenance & Repair

have a question about my 2009 hyundai elantra heating issues. at first the switch wouldnt turn on until i started driving the car and it blew out cold air. They changed the fan relay (?) switch. After that the switched turn on when i started the car. However, after warming the car up for 45 mins its only slightly warm? They now changed the gasket, blower motor resister & the thermostat. And they also did a heater core flush. As of now, when I start the car the air is cool, after driving the car for a while the heat will work well, but when i stop at a traffic light cool air comes out? And then when I hit the gas again to drive the heat comes back on. Can it be the blend door actuator?

find another garage , sounds like they use guess work instead of testing ,, make sure the coolant is full , there may be an air pocket ,
