SOURCE: 2005 Pontiac Gran Prix blower
Check the blower motor which is behind the right side of the dash, in the lower right side of the HVAC Assembly, above foot area of the passenger floor. The other thing to test is the blower motor resistor which should be next to the blower motor.

The blower on my 2005 Bonny GXP quit at about 60,000 miles (I really like using High). The blower is under the passenger dash. Mine had a three wire connector. The center wire should have 12 volts. It doesn't take very long to pull the fan out. Mine was toasted. Aftermarket fan was about $130.
See this website for my instructions:

Just an philips screw, you'll need to remove screws that are by the door handle,
arm rest, under door and side of door and then gently pull back on the
panel as there will also be retaining clips attached and you don't want
to break them.
If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door.
Hope helped with this (remember rated this).

DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the
The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage is higher or lower than required, DTC P0641 will set.
Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the 5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. A current DTC, Last Test Failed, clears when the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.
Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.
Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.
