The diagnostic process for the heating and cooling is a very long and involved process and requires a couple of specialized diagnostic tools that you may not have.
Here are some of the easier things to physically check, which can be preventing the proper function of the seats:
Mechanical
The pontiacs have an issue with the ignition switch, I have a 2001 grand prix that did the same. The ac fan would only work on 5 and the headlights would go off if on 1-4 replace the switch and all is fine.
Firstly, try disconnecting both your battery connections, and with the battery disconnected, turn the ignition switch fully, 3- 4 times ( To just discharge the computers ) Then reconnect the battery cables (pos + ) first. This usually cures your problem.
Electronics involved !
The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the dual automatic temperature controller (EATC) located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (dual CCSM) located underneath the passenger front seat cushion.
Both the driver and front passenger climate controlled seats are independently controlled electronically by the dual climate controlled seat module (CCSM) mounted to the bottom of the passenger seat cushion. The climate controlled seat system only operates with the engine running, however, if using a diagnostic tool to command the dual CCSM, diagnostic testing can be carried out with the ignition switch key ON engine OFF (KOEO). The system receives power from central junction box (CJB) fuse 118 (30A) through circuit 1153 (RD/BK) feeding battery voltage into dual CCSM C3265b pins 1 and 24. If power is disconnected from either pin 1 or 24 of dual CCSM C3265b, only 1 seat will be disabled (pin 1 for driver seat, pin 24 for passenger seat), the other will remain operational. Since both climate controlled seats operate independently, if a fault occurs setting a DTC specific to either climate controlled seat, only the affected seat will be disabled by the module and the other will remain operational.
Sorry , but it would be best for you to take it to the dealer or someother qualified repair shop.
