My 2003 Pontiac Aztek won't shift out of park. The button on the shifter won't depress and it seems to be happening with increasing frequency. What is the problem?
have the same problem?

Check brake light and brake light switch
Gearshift lever cannot be moved from "P" position without simultaneously applying brake pedal with ignition switch turned to ON position. When brake pedal is applied, brakelight switch completes or interrupts circuit to BTSI solenoid. Depending upon application, energizing or de-energizing BTSI solenoid unlocks gearshift lever from "P" position
Transaxle/Transmission shift interlock system prevents driver from moving gearshift lever from "P" position unless ignition switch is turned to ON position. On models equipped with Brake Transmission Shift Interlock (BTSI) solenoid, gearshift lever cannot be moved from "P" position without simultaneously applying brake pedal with ignition switch turned to ON position. Shift interlock solenoid is located at gearshift lever in steering column or center console.
