Hi, my name is ***** ***** certified automotive professional with over 25 years experience. I will be glad to assist you with this.There are a couple of things to check first, make sure that the temp gauge is moving normally from the 0 degree mark to the normal mark (about half way) . If it isn't then replace your thermostat. Those symptoms will indicate a bad or sticking thermostat.
Secondly if the gauge is moving normally, the next thing is you may have a problem with the blend door actuator.
