Part# W0007967 - Workhorse W-series Wiper Control Module


Workhorse recommends adding a 15 amp Mini Auto Reset Circuit Breaker in place of the 25 amp fuse in position # 22 on your interior fuse panel. This prevents too much current from damaging the module, and will trip the breaker momentarily instead.

Product Memo
To: Original Equipment Manufacturers
From: Workhorse Custom Chassis 08/23/2007
Subject: WCC Wiper Module Rating for W-series chassis and LF series chassis (WCC P/N W0007967)
Product Memo: 07-08-01-A
 
The Wiper Module is a device which interprets the low and intermittent wipe output from the column mounted
wiper switch and supplies power to the wiper motor and the washer pump accordingly.

The specifications for the Wiper Module are as follows:

Wiper Motor Maximum Current:
8 A continuous current rating
Wiper Motor Maximum Stall Current:
16 A continuous current rating at -40°C to 0°C ambient
temperature
Washer Pump Maximum Current:
10 A continuous current rating

The wiper circuit is protected by a 25 A mini fuse in position 22 of the internal fuse box.
Reports from our Service organization have indicated that vehicles fitted with Wiper Technologies Wiper
Motors (supplied by Diesel Equipment), have experienced failed Wiper Modules. It has been determined that
these motors exceed the electrical specifications of the Wiper Module as well as the wiper circuit fuse rating.
Workhorse has conducted extensive bench testing with wiper systems fitted with a 15 A Type 2 automatic
reset circuit breaker. Based on the test results, chassis equipped with the 15 A Type 2 automatic reset circuit
breaker, will have the following wiper system rating:

Wiper Motor Maximum Current:
10 A continuous current rating
Wiper Motor Maximum Stall Current:
Current supplied to the wiper motor under stall conditions
will be capped at 15 A (refer SAE J553 for automatic reset
circuit breaker rating at elevated ambient temperatures)
Washer Pump Maximum Current:
5 A continuous current rating

Consequently, Workhorse will be replacing the 25 A mini fuse with a 15 A Type 2 automatic reset circuit
breaker for W16/18/20/21/22/24/25/42/62 and LF72 chassis.

Workhorse further recommends that Final Stage Manufactures use wiper motors equipped with thermal
overload protection. Final stage manufactures should also test and validate the complete wiper system for
due diligence as well as to ensure compliance to all related FMVSS regulations.
