NEED HELP 2005 TB EXT REAR DIGITAL HVAC/RADIO CONTROL

[twistintommy]

Hi all,

First post here.

I can control the radio Source and Seek from the rear controls but I cannot control any of the HVAC functions. When pressing any of the HVAC buttons the display just blinks. Can any one kindly tell me what I am doing wrong, what am I missing?

Thanks!

Welcome to the Nation!

How long have you had the truck? Just guessing that it could be a bad controller. Is yours an EXT? If so, be sure the fan control next to the shifter is set to rear. I don't use it except to put on the fan to push a little air in the back for cooling but I think I remember that I had to push the power button to activate it on my 9-7x.
