Check the blower relay, its only energized at HIGH speed. Check your voltage at the blower motor, when turned on to High, Purple wire, be sure it has 12V. Black wire should read "0" volts (ground). The Purple wire gets power from A/C Fuse 3 (30A) underhood relay/fuse box/ right side. High speed gets power directly through the relay, all other speeds go through the resistor. The Blower relay is the 3rd one on the firewall I believe, there may be other relays you can swap and see if the blower comes to full speed.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
