TVM TRAVERMAN Blower Motor Resistor 5‑Pin for GM Cars & Trucks (13503201) — OEM Fit, Aluminum Heat Sink

This TVM TRAVERMAN 5‑pin blower motor resistor (part 13503201) restores multi‑speed HVAC fan control on compatible GM vehicles by replacing a failing resistor module.

When a vehicle’s heater or air conditioner only runs on high or loses lower fan speeds, the blower motor resistor is often the culprit. The TVM TRAVERMAN resistor is engineered to OEM tolerances and designed as a direct, no‑modification replacement for many Chevrolet, GMC, Buick, Cadillac, Saturn and Pontiac models. It controls the current to the blower motor so the fan runs smoothly at all selected speeds and resists heat and vibration common in under‑dash HVAC locations.

How will this resistor fix my fan running only on high?

A failed resistor typically opens or shorts the lower‑speed circuits, leaving only the high‑speed path intact. Replacing the resistor restores proper resistance and current routing so each fan speed works again.

• Replaces damaged 5‑pin resistor circuits that control low/mid fan speeds.
• Precision aluminum pin‑fin heat sink dissipates heat to prevent repeat failures.
• OEM‑level housing and connector match original fit and function for plug‑and‑play installation.

Which vehicles are compatible with this 5‑pin unit?

This part fits many GM platforms produced across the 2007–2020 model years — verify the original resistor has a 5‑pin connector before ordering. It does not fit 7‑pin versions used in some models.

• Chevrolet: Silverado 1500/3500HD, Equinox, Cruze, Malibu, Tahoe, Suburban, Camaro, Avalanche, Captiva Sport, Caprice, SS.
• GMC: Sierra 1500/2500HD/3500HD, Terrain, Yukon/Yukon XL.
• Buick/Cadillac/Saturn/Pontiac: Enclave/Encore/LaCrosse/Regal/Verano/Lucerne/Cascada, Escalade/CTS/SRX/DTS/STS, Vue/Outlook, Torrent.

What materials and design features improve durability?

TVM TRAVERMAN builds this resistor to meet OEM standards using a reinforced polymer housing and a high‑efficiency heat sink to extend service life in the hot, vibrating environment under the dash.

• PA66‑GF/M reinforced nylon lower housing for strength, thermal resistance, and vibration stability.
• Aluminum pin‑fin heat sink for improved thermal dissipation and circuit protection.
• Electronic layout and connector designed to match OE electrical performance and mounting points.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone comfortable with basic hand tools and working beneath the passenger dash. The resistor is accessible after removing the lower trim panel and disconnecting the wiring harness.

• Typical tools: Phillips or Torx driver to remove mounting screws and trim fasteners.
• Procedure: remove lower passenger trim, unplug resistor harness, unfasten screws, replace with new unit, reconnect and test.
• Direct fit design avoids cutting or splicing — expect a quick repair that saves shop time and costs.

Who is this for: This TVM TRAVERMAN 5‑pin blower motor resistor is for owners and technicians working on compatible Chevrolet, GMC, Buick, Cadillac, Saturn, or Pontiac models that have lost low or medium HVAC fan speeds or run only on high. It’s suited to DIYers who prefer a plug‑and‑play OE‑style replacement and repair shops looking for an OEM‑level, cost‑effective option. Confirm your vehicle’s original resistor is a 5‑pin configuration and matches one of the listed OE part numbers (for example 13503201, 84178783) before purchase.
