"Pressurization Problem Forces America West Flight to Land in Boise

BOISE, Idaho (AP) - Oxygen masks deployed and a few passengers experienced nausea Friday when an America West Airlines plane lost cabin pressure en route from Seattle to Phoenix and was forced to land in Boise. The Boeing 737-300 with 134 passengers aboard landed about 11 a.m. A crew was trying to determine what caused the decompression as the plane was cruising at 33,000 feet, America West spokeswoman Patty Nowack said."

Likely a door seal has worn out or was pinched and served as the starting point for a seal blowout. Cabin pressurization systems are pretty much basic pnuematics with analog instrumentation. They are kept very simple for safety purposes.
