If your catalog team picks a window regulator because the listing names the right model and the motor plug looks familiar, you may be about to order the wrong mechanism. A vehicle name alone does not identify a regulator. The mechanism, the rail or arm layout, the glass attachment, and the mounting all have to match the exact door. Many listings leave several of those details out.
The article starts with the two common designs. A scissor-type regulator uses two hinged arms and a toothed sector. A cable-type regulator runs cables over pulleys, with the glass carried along a vertical track. "Gear-driven" is not a third design. Gears appear inside both, so that label says something about the drive train and nothing about the arm layout, rail count, or glass attachment.
It then looks at two Dorman Products pages. The 741-642 power regulator and motor assembly lists a bolt attachment, a wiring harness, and six OE cross numbers. It also states that mounting hardware and installation instructions are not included. The page does not say whether the mechanism is cable or scissor, how many rails or arms it has, which door it is for, or how the glass attaches. A listing can look complete and still be silent on the fields that decide the match.
Our latest knowledge article offers a verification record with one row per candidate:
Mechanism: cable, scissor, or other
Rail or arm count, compared with the removed part
Door position and side
Motor interface, including connector and plug shape
Glass clamps and attachment method
Mounting hardware, and whether it is included
Year, make, model, market, and the old part's identifying numbers
A field the source does not state is marked "not stated" and put on hold. An OE number is a lead, not proof. The article's hypothetical case shows how a matching model name and a similar plug can still produce a cable unit for a scissor door. The result is a returned part and a delayed order. Installation steps, motor initialization, and torque values come from the vehicle's service information or a qualified technician.
For purchasing teams, workshops, and fleets, a short record like this can cut returns and delays.
