Standard supports all key engine components and systems with a full line of accessories and electronic relay solutions, including blower motor resistors, daytime running light kits, and TechSmart® HID headlight ballasts.

Blower Motor Resistors

On most full-size GM trucks and SUVs from 2001–2007, the blower motor resistor has two common failure modes: water damage and excess heat. The GM vehicles are unable to manage condensation. If the duct is clogged, condensation will collect, creating a pool of water that can seep into, and flood the blower motor  resistor module. Worn OE blower motors can create a demand for current that also damages the module. The excess current melts the wiring and plastic shroud, damaging the interface pins on the controller’s circuit board.

Standard’s RU631 Blower Motor Resistor features several improvements over the OE, including an umbrella cover design that prevents water intrusion and a larger-output power device and upgraded two-ounce copper board that protects against overheating.

TechSmart® HID Headlights Ballasts

Despite their superiority to halogen headlights, HID Headlights can still fail, typically from overheating, moisture intrusion, damage from a frontal collision, or burning out from repeated duty cycles. If one of those scenarios occurs, it can cause the system to become inoperative, creating reduced visibility and safety concerns for drivers and motorists.

To help restore proper lighting function to HID light systems, we created OE-Exact Match HID Headlight Ballasts. That means they are direct-replacement parts that match the fit, form, and function of the originals. Plus, as DOT-certified parts, our HID Headlight Ballasts comply with Federal Motor Vehicle Safety Standards.
