GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi. Does your Denali have manual climate control or automatic? And is it dual zone temp control?
Ok. What side temp actuator needs replacing?
Yes we are.
To replace the RH temp actuator, you need to remove the center console if equipped. Then you need to remove the entire dashboard. Then the actuator is easy and held on by 3 screws.
Taking the steering column out. Remove all the trim pieces. removing the hvac module, the instrument cluster, then removing 3 bolts and 4 nuts.
There is a lot to the job. Book time is 6 hours to replace the actuator. And honestly that time is for someone who has probably done a few of them. The actuator is on the heater box. It can be seen after the dashboard is removed. There are shop manual instructions on how to remove the dashboard.
