Remedy

Reprogramming Passenger Door Module Owners of some 2003 Chevrolet and GMC full-size pickups and utilities, Cadillac Escalade models and Hummer H2 may have concerns that the RKE key fob does not function, the front passenger door power window, lock, mirror and heated seat are inoperative. The Door Lock and Side Window Switch contains a microprocessor called the Passenger Door Module (PDM). The condition and repair procedure involve the PDM. - Those built before 01/03 -- refer to Bulletin 03-08-52-001C. - Those built during 01/03 -- refer to Customer Satisfaction Bulletin 03-011. - Those built 02/03 or later -- refer to published Service Information for the symptom experienced by the customer. Instead of replacing the Door Lock and Side Window Switch, you can now refresh and reprogram the PDM using your Tech 2. TIP: Your Tech 2 must contain software 23.001 (CD 3) or newer, released March 8. If it does not, you must download this software before proceeding. And once you have identified the correct bulletin, you MUST perform the procedures described in it, in the order given, and do not skip any steps.

Remedy

Power Seat Memory Position This information applies to 2003-05 Chevrolet and GMC C/K trucks and utilities and Hummer H2. The memory seat may recall to a more-forward position than previously set. This concern may be difficult to duplicate, and the position may change gradually over time. Do not replace the memory seat module. Engineering has found the cause to be a coding deficiency in the software of the memory seat module. New memory seat module software was released in TIS version 4.5, dated April 18, 2005.

Cause

Certain vehicles equipped with rearward folding head restraints on the second row seats. Two potential pinch points exist on each of the folding head restraints when the head restraint(s) are folded rearward as the seatback is folded down. If a person were to insert their finger(s) into the pinch point when the head restraint folds, it could trap and pinch the finger(s) causing injury. Correction: Dealers will install protective covers over the pinch points.
