Marsflex Blower Resistor For Chevy GM (89019088)
This manual-AC blower motor resistor is designed for GM vehicles, including 2003-2006 Avalanche, Silverado, Suburban, Tahoe and related models. The product notes emphasize comparing appearance, pin quantity, and installation holes to ensure proper fit. Best for owners replacing a non-variable fan speed module in older GM trucks and SUVs. A limitation is potential variation in OE part numbers across similar resistors, so verify compatibility before purchase.
A-NAFTULY HVAC Front Resistor For Honda And More
This resistor supports many Honda (and some Acura) models with auto AC controls, including 2003-2012 Honda Accord/Civic/CRV and related entries. It also references multiple replacement part numbers to help verify fit. Best for Honda/Acura owners seeking a broad compatibility option. Better for vehicles that require a specific 79330-SDA-A01 family part; beware mixed part numbers can complicate fitment.
Marsflex Blower Resistor For 1999-2006 Chevy Silverado Suburban
Designed for manual AC control, this Marsflex unit covers multiple GM trucks from 1999-2006, including Silverado and Suburban models. It specifies various Silverado generations and 2000 Suburban years as compatible. Best for owners replacing a failed speed control on older GM pickups. Limitations include the need to confirm mounting holes and pin alignment with the original part to avoid installation issues.
FAERSI 89019089 Blower Resistor Kit
This 89019089 kit is crafted for manual AC controls on a broad GM lineup (Chevrolet Avalanche, Silverado, GMC Sierra; Cadillac Escalade). It lists a two-hole mounting flange and references multiple OEM numbers for compatibility. Best for model-year matching within the 1999-2006 GM range. Caution: always verify the model/year and mounting configuration before purchase due to numerous interchangeable part numbers.

Buying Guide: Key Purchase Considerations
- Compatibility: Always confirm year, make, model, and OE part numbers. Variations in mounting holes and connector types are common even within the same vehicle family.
- Control Type: If your vehicle uses manual AC control, ensure the resistor is designed for manual operation. For automatic climate control, verify electronic compatibility.
- Installation Fit: Compare the pin count and mounting flange (two-hole vs two-hole with different spacing) to avoid fit issues.
- Quality and Materials: Look for hard-plastic housings and robust connectors to resist heat and vibration in trucks and SUVs.
- Ease of Replacement: Choose a unit with clear mounting points and straightforward electrical connections to reduce installation time.
Frequently Asked Questions
- What does a blower motor resistor do?
It controls the speed of the HVAC blower fan by varying electrical resistance in the circuit, enabling multiple airflow speeds.
- How can I tell if my resistor needs replacement?
Symptoms include the blower only working on one or two speeds or not at all, along with inconsistent airflow.
- Do all 2004 GM vehicles use the same resistor?
No. Fitment depends on exact year, trim, and mounting configuration. Verify part numbers and mounting holes.
- Is it safe to replace a blower resistor myself?
Yes, with the vehicle powered off and battery disconnected. Follow the vehicle’s service manual for discharge and wiring steps.
- Can I use a resistor from a different brand?
Compatibility is best when the part matches original OE specifications or part numbers listed by the manufacturer.
