Hello. My 2002 GMC Envoy changes from 2wd to 4hi and 4lo on its own when I start it. And then when it does change to 4hi, in reverse it does it with hesitation. What do you think the problem is?

Check the wiring to the 4wd actuator on the transfer case. Make sure there is no damage and the wiring plug is not damaged or corroded.
