A rather miraculous fix happened for me on a 1998 Buick Regal with an ABS (Antilock Brake System) problem. Contrary to what most people think, ABS brakes only come into play on an emergency stop, metering hydraulic pressure to the rear brakes with Rear Wheel Antilock Brake Systems, or all four wheels with Four Wheel Antilock Brake Systems to prevent wheel lock up. The codes I scanned indicated problems with the ABS Modulator Motor Pack. I took the wrong note sheet in with me and ordered a Motor Pack kit from the Delco warehouse for the Traction Control Modulator Motor Pack. I had disassembled both units because sometimes the gears in the Traction Control Modulator Motor Pack cause a code indicating problems with the ABS Modulator Motor Pack. Since scanning for codes only points you in a certain direction, the mechanic has to cover all the bases.
Before the eyes start glazing over out there on this too much info moment, let me get to the point. I ordered the wrong motor pack, and was sent the right one. This small miracle allowed me to finish the job on time for the lady who had an appointment today at noon. Most would say, ‘oh… nice coincidence… lucky you’. Having worked in this industry for thirty-six years, I’m here to tell you no such lucky coincidence ever happens, at least not to me. When you call a parts person and order the wrong part, you get the wrong part. The resulting mess of a late finish on the job due out, and backed up appointments, reminds you for many years after to be more careful. Parts people make mistakes, but they’re never made accidentally in the shop mechanic’s favor. The chances of it happening rival getting hit by lightning. Only one explanation… divine intervention… amen. :)
