PANNUOSCS Blower Motor Resistor for Hummer H2 2003-2007 — Direct-Fit, Copper-Core Socket Restores Multi-Speed HVAC

PANNUOSCS blower motor resistor is a direct-fit replacement for Hummer H2 (2003–2007) that restores heater and A/C fan speed control by matching original fit and performance.

If your Hummer H2’s blower only works on one speed, blows inconsistently, or stops responding to fan controls, a failed blower motor resistor is often the cause. This PANNUOSCS module is built to the original equipment specifications and designed specifically for automatic temperature control systems on H2 models between 2003 and 2007. The unit uses a copper-core socket and robust materials to resist heat, vibration, and electrical wear so your HVAC system regains reliable multi-speed operation.

How does this resistor restore my Hummer H2’s fan speeds?

The resistor replaces the circuit that modulates current to the blower motor, allowing the fan control knob or automatic system to select multiple speeds. It replicates the original geometry and electrical characteristics so the blower responds as it did from the factory.

• Direct-fit design for Hummer H2 2003–2007 models
• OEM-referenced part numbers for accurate matching (e.g., 19331830, 93803637)
• Copper-core socket for stable electrical contact and heat handling
• Restores full multi-speed fan control for heating and A/C

Which part numbers and vehicles is this unit compatible with?

This PANNUOSCS blower motor resistor is intended to match specific OE numbers and fit Hummer H2 years 2003 through 2007 with automatic temperature control. Always cross-check your original part number to ensure compatibility before ordering.

• Common OE references: 19331830, 89023355, 93803637, 88986529
• Additional references included: 15-80388, 15-80655, 15-80911
• Other coding: 3GSH-19E624-CA, 4GSH-19E624-AA, 6GSH-19E624-AA
• Designed specifically for Hummer H2 (2003–2007) automatic temperature control systems

What materials and construction improve durability compared to cheap alternates?

PANNUOSCS uses a reinforced copper-core socket and heat-resistant components to reduce hot spots and poor connections that lead to failure. The assembly is validated to resist vibration and aging that often cause intermittent fan operation in older HVAC modules.

• Copper core reduces electrical resistance and overheating
• Impact- and heat-resistant housing for long service life
• Quality control testing to ensure safe, reliable operation
• Plug-and-play connector for straightforward installation

How difficult is installation and what should I check before replacing it?

Installation is typically straightforward and requires basic hand tools and access to the blower housing under the glove box. Confirm that your vehicle uses an automatic temperature control system and compare OE numbers to the listings; improper selection could result in incompatibility.

• Verify automatic temperature control requirement before purchase
• Compare your existing resistor’s part number to OE references listed
• Access usually through the glove box or underdash panel; expect a 15–45 minute job
• Reconnect harness securely to avoid poor contact and future failures

Who is this for: This PANNUOSCS blower motor resistor is aimed at Hummer H2 owners, mechanics, and DIY enthusiasts who need a reliable, OEM-quality replacement for faulty fan-speed control in 2003–2007 models with automatic temperature control. It’s a practical repair option when the blower only works on one speed, is intermittent, or has lost several fan settings. If you’re restoring proper HVAC function with a durable, tested part and want compatibility with known OE numbers, this module provides a cost-effective solution with a 12-month return/exchange policy for added confidence.
