GMC ENVOY HEATER PROBLEM

2003 GMC Envoy • 40,500 miles

When starting a truck in the morning, the heater fan does not start, I have to play with it for a min. What is the cause?

It could be a few things. However, if you are playing with the switch and it starts working, that would be my first guess.
