A-Premium Windscreen Wiper Motor Pulse Board 5‑Pin 12V Replacement Module — Direct‑Fit Intermittent Control

The A-Premium Windshield Wiper Motor Pulse Board is a direct-fit 12V replacement module that restores intermittent wiper control for many GM and allied vehicles.

If your windshield wipers skip intermittent settings, stop responding, or only work on one speed, this pulse board rebuild component offers a practical repair alternative to replacing the entire motor assembly. Designed as a compatible replacement part, it installs in the front windshield wiper motor housing and reconnects the intermittent timing and park functions for original equipment that uses a 5-pin connector.

Which vehicles and trims will this pulse board fit?

This pulse board is manufactured to match factory connections and electrical behavior for numerous GM platforms from the 1990s and 2000s. It lists broad compatibility across Chevrolet, GMC, Cadillac, Oldsmobile, and Pontiac models commonly fitted with a 5-pin windshield wiper motor interface.

• Chevrolet: Tahoe, Astro, Blazer, C1500/2500/3500, K1500/2500/3500, Kodiak C60/70/5500/6500/7500, Express 2500, G10/20/30, P30, S10, Lumina APV.
• GMC: Yukon, Jimmy, Safari, Sonoma, C1500/2500/3500, K1500/2500/3500, G1500/2500/3500, P3500.
• Also compatible with Cadillac Escalade, Oldsmobile Bravada and Silhouette, Pontiac Trans Sport.

How does installation work and what electrical specs should I check?

Installation involves opening the wiper motor housing, swapping the old pulse board for this replacement, and reconnecting the factory 5-pin plug. Ensure the vehicle battery is disconnected before you begin and verify the board matches the motor’s mounting points and connector pinout.

• Rated voltage: 12V — compatible with standard automotive electrical systems.
• Plug type: 5-pin connector; match pin orientation before final assembly.
• Part numbers referenced: 906-136, 88136, 172361, 61-7000, 61-7001, 6H1385, 81-158PB, and GM OEM numbers like 12367224, 12463017.

What symptoms indicate the pulse board needs replacement?

Typical signs the pulse board has failed include loss of intermittent wipe, wipers stuck in a single speed, wipers not returning to park, or complete intermittent control failure while other speeds still work. Diagnosing before ordering will avoid unnecessary part exchanges.

• Intermittent function stops but continuous speeds operate normally.
• Wipers fail to return to their parked position at key-off.
• Erratic or no response from the wiper switch in intermittent mode.

Will this pulse board restore OEM performance and what should I expect after replacement?

When installed correctly on a motor with otherwise sound mechanics and wiring, the pulse board restores intermittent timing and park behavior to near-original function. It replaces the electronic timing portion of the assembly, but won’t fix mechanical wear in linkages or a failing motor armature.

• Restores intermittent timing and park switch functions when used with a healthy motor.
• Designed as a cost-effective alternative to full motor replacement.
• Test wiper operation and park position after installation before sealing the motor housing.

Who is this for: This A-Premium Windshield Wiper Motor Pulse Board is aimed at DIY mechanics, independent repair shops, and owners of older GM-derived vehicles who want an economical repair to regain intermittent wiper control. It’s especially useful when the motor runs but intermittent timing or park functions are faulty; verify vehicle compatibility, connector type, and part number cross-references before purchasing to ensure a proper fit.
