Fixed dual climate control!

[mojo0107]

I posted this in another Thread...I don't know but Hope it will work for you.
Make sure the Unit has not thrown any Codes...
1. With Truck off
2. Pull the HVAC/ECAS fuse (under the hood) for at least 20 seconds, if you don't have a watch you can count to 22 Mississippi
3. Put the fuse back in place...
4. Put key in and start the truck...
5. DO NOT TOUCH A DARN thing...(That’s what caused my problem after dead battery)
6. After 1 min. the ac control module should self-Calibrate...

This is how the guy fixed mine, I watched and counted so I may be off by a few seconds...Hope it works for you. I've got Cold air just in time for winter
