The GM3 and GM5 General Modules are commonly faulty. These devices have circuit relays that can fail resulting in a multiplicity of annoying problems. Mechanics will often try to replace a variety of components realizing that was not the solution. The general module is also something that is coded to your specific vehicle, so repairing it is a better option than replacing it. 

How to Determine if This is the Problem You Have:

Most problems are either the Door Lock Actuator assembly or the GM5 module. Sometimes the problem is hard to determine. Usually, GM5 problems occur with unlocking much, much, more often than locking. Here are a few symptoms for determining which is the faulty part:
4-door - all 4 doors fail to unlock -> GM5
4-door - all 3 passenger doors fail to unlock -> GM5
4-door - only 1 of the passenger doors fails -> Actuator
2-door - both doors fail to work -> GM5
2-door - only the driver's door fails -> indeterminate
2-door - only passenger door fails -> indeterminate
Problem seems to be worse in hot or cold weather -> GM5
Fuel filler door doesn't unlock either -> GM5
