This part cross-references / interchanges with the following part numbers:
Will this Blazer window regulator fit my 1987-1991 Chevrolet Blazer?
Yes. The 1987-1991 Chevrolet Blazer is a listed application for the front right door, and the part fits many other Chevrolet and GMC trucks too. The "Vehicles it fits" section has the full list.
Does the 740-650 include a window motor or glass?
No. It is a manual, crank-operated window regulator sold as the regulator only, so it has no motor and does not come with window glass.
Which door does this regulator fit?
Dorman catalogs the 740-650 for the front right door position on the listed applications.
What are signs a window regulator may need replacing?
Common signs are a window that drops, tilts, binds or moves slowly, grinding or clicking when you turn the crank, or glass that won't stay up. Confirm the cause first, since a worn crank handle can cause similar symptoms.
How was this window regulator tested?
Dorman cycled it thousands of times in an actual vehicle door. It was reverse-engineered to the original equipment shape and dimensions for a direct fit.
