HVAC control - 11/15/2008 5:55:52 PM

My HVAC works for the most part. However, the drive side changes to blow just heat and will stay that way. I can change the digital read of the numbers but that does not change the actual air temp. At first I thought the climate control module was broke. Now I think it is the actuator. Can anyone help with info on this.

For those who looked here and did not know the info here is what I did. I found out that there are 4 different actuators in the H2. 2 for temp and 2 for mode. The driver side temp actuator is on passenger side above the passenger side actuator both are temperature actuators. 1 actuator is one driver side this is by the gas pedal just to the right of it. this controls a mode door. The other is on passenger side connected to the mode door next to the passenger door. None of which are easy at all to get to. DO NOT ATTEMPT. These actuators cost almost $300 for the temperature and $80 for the mode actuators (each). Hummer has replaced several driver side temp actuators without having a recall. This is how they make money.
