It is best for buyers looking for a factory-style replacement that minimizes wiring changes and preserves original performance characteristics. This part is typically compatible with a range of older GM and non-GM models that used similar pulse boards. A potential limitation is that compatibility can vary by model year, so verify fitment before purchase.

A-Premium Windshield Wiper Motor Pulse Board
This A-Premium unit is designed for broad GM family compatibility, including Chevrolet Tahoe, Blazer, Astros, and GMC Yukon/Jimmy models from 1988 to 2005, as well as Cadillac Escalade and several Oldsmobile and Pontiac variants. It’s a strong choice for owners replacing worn pulse boards in a mixed-GM fleet or a single vehicle with multiple wiper configurations. Best for buyers who want a single part that covers many GM platforms. A caution is that some older models may require minor wiring checks or reseating of connectors during installation.
Dorman 906-118 Wiper Motor Pulse Board
Designed as a direct-fit replacement for select models, the Dorman 906-118 is ideal for vehicles that require a precise fit with minimal modification. It’s best for buyers who value compatibility with a defined subset of models and straightforward installation. A potential limitation is that this module may not cover all trims within a vehicle family, so confirm the exact model fit before ordering.
Dorman 906-136 Wiper Motor Pulse Board
The 906-136 offers an alternative fitment for a range of GM and Chevrolet trucks, including some Tahoe, Suburban, Silverado, and Silverado-like models. Choose this if your vehicle falls into the specified fit matrix and you need a reliable, factory-style pulse board replacement. Best for buyers maintaining a mixed-model fleet where a common replacement strategy benefits inventory. A limitation is that some late- or early-production variants may require additional adapter work.
Dorman 906-109 Wiper Motor Pulse Board
The 906-109 model is a practical option for several older GM platforms and other vehicles that share a compatible pulse board topology. It’s best for buyers who want a balance of broad compatibility and straightforward replacement steps. A caution is that cross-model compatibility is not universal, so verify against your vehicle’s exact make, model, and year to avoid mismatches.
