On the new 2007 full size utilities (Cadillac Escalade, Chevrolet Tahoe and GMC Yukon) with RPO CJ2 or CJ3, a replacement HVAC control head must be programmed using TIS.
TIP:Â When a replacement control head is installed, it may appear to be operational, but if not programmed some functionality will be lost.
