GM Envoy: , I have a 2002 gmc envoy and when the heat

Customer Question

Hello, I have a 2002 gmc envoy and when the heat is on the heat comes out of the drivers side but the passengers side comes out cold. Could this be due to the heat control being bad or is there a sensor somewhere? Thank you.

Welcome! My name is ***** ***** I will do my best to assist you with this problem.
I am sorry for the long wait
99 % of the time when the passenger side temp works fine and the drivers side temp is the one acting up the problem is just the drivers side temp actuator bad
a very common issue on these
replacing the drivers side temp actuator should correct this issue
the labor to change that actuator is @ 5 hours as the complete dash needs to be rolled back or removed to access that actuator and the actuators range from @ $ 50 to $ 80
