NewYall Blower Motor Resistor for Chevrolet & Pontiac - Fits 15818910 / Restores Fan Speed

NewYall HVAC blower motor resistor for part numbers 15818910, 88973260, and 79548987 restores fan-speed control in compatible Chevrolet and Pontiac models.

If your vehicle's heater or air-conditioning fan is stuck on one speed or stops working altogether, this NewYall blower motor resistor is a direct-replacement component engineered to match OE fit and electrical characteristics. Designed for specific Chevrolet and Pontiac sedans and compacts, it provides a quick, budget-friendly repair option that avoids replacing the entire blower assembly.

Which cars will this resistor fit?

This resistor is made to fit a small group of GM models from the mid-2000s. Check the model years and part numbers to confirm compatibility before ordering; cross-referencing VINs or the existing resistor part number ensures a correct match.

• Chevrolet Cobalt: 2005–2010
• Chevrolet HHR: 2006–2011
• Pontiac G5: 2007–2010
• Pontiac Pursuit: 2005–2006
• Compatible part numbers: 15818910, 88973260, 79548987

How simple is the installation and what tools are needed?

Installation is typically straightforward for anyone comfortable working around the glove box and under-dash area. Most replacements require only basic hand tools and no specialized equipment, and many owners can complete the swap in under an hour.

• Basic tools: screwdriver set, socket wrench, and possibly trim removal tool
• Typical steps: remove glove box or access panel, unplug connector, unbolt resistor, install new unit
• Time estimate: 30–60 minutes for a DIYer

What symptoms indicate the resistor is failing?

A malfunctioning blower motor resistor commonly affects how the fan responds to speed settings. You may notice the blower only works on high, moves intermittently, or doesn't work at all—symptoms that point to the resistor rather than the fan motor itself.

• Fan operates on a single speed (usually high) only
• Fan speed settings are unresponsive or inconsistent
• No fan operation at any speed in some cases
• Electrical smell or heat near resistor area (inspect carefully)

Does this replace the entire blower motor assembly?

No — this part replaces only the resistor that regulates the blower motor's speeds. Replacing the resistor often restores normal fan control without the cost and labor of changing the full blower motor or HVAC housing.

• Resistor-only replacement is lower-cost and less invasive
• Replace the blower motor if the fan still fails after installing the resistor
• Inspect connectors and wiring for corrosion or damage during replacement

Who is this for: This NewYall blower motor resistor is intended for owners and mechanics working on mid-2000s Chevrolet Cobalt and HHR models, or Pontiac G5 and Pursuit vehicles, who need an affordable, OE-fit replacement for part numbers 15818910, 88973260, or 79548987. It’s ideal for DIY enthusiasts and independent shops seeking a reliable component to restore HVAC fan speed control without replacing the entire blower assembly.
