This problem happened to me last year on my '01 SE. If you are voltmeter-savvy, at the fuseblock near the glovebox, check the voltage at the hvac fuse with ignition on and the blower selected at position 1,2,3 or 4. My voltage was only around 8vdc due to the bad contact in the ignition switch. Voltage will probably be found normal in position 5 because thed 12v is routed differently in that position. Changing the switch was not too bad of a job, but a small torx head socket was required to remove the switch hardware. Good luck!
