Product Description
A blower motor resistor regulates current to the HVAC blower motor, enabling multiple fan speeds. In heavy-duty equipment, resistor plates operate under higher heat load and long duty cycles. Open-coil resistor plates are widely used because airflow in the HVAC duct helps cool the resistor element during operation.

Stable resistance performance under continuous HVAC blower loads, supporting consistent fan speeds in truck HVAC systems.
Improves airflow around the resistor element to enhance heat dissipation and reduce overheating risk.
Designed for vibration resistance and stable installation on heavy-duty trucks and commercial vehicles.
Common symptoms of a faulty blower motor resistor include:
Only one fan speed works
Blower runs intermittently or stops
No airflow from vents
Burnt connector or overheating smell
Unstable cabin temperature control
Confirm terminal layout and mounting pattern before installation
Replace melted connector housing if overheating occurred
If repeat failures happen, inspect blower motor current draw and wiring resistance
Professional installation recommended for workshops and fleet environments
From a manufacturer's standpoint, the most common field issues come from overheating and poor terminal contact. Our batch-level controls focus on:
Resistance stability and electrical continuity checks
Terminal contact and alignment inspection
Assembly consistency for bracket positioning
Heat endurance verification for production batches
For distributors and importers, stable packaging and shipment execution matter as much as product quality. We prepare bulk orders with export-standard carton packing, palletizing, and container loading. Before shipment, we can share loading photos and packing details to help you manage receiving and warehouse operations.
Export-grade cartons with clear carton marks (OE No. / qty / batch)
Palletizing + stretch wrap to reduce damage during long-distance transport
Container loading with space optimization for bulk shipments
Mixed-SKU consolidation support (send your part list for packing plan)
Shipment photos available for your receiving & documentation process
MOQ note: MOQ is 100 pcs per item. For bulk orders, share your destination port and order mix—we'll propose an efficient packing and loading plan.
For distributors and importers, the key to a smooth first order is fast and accurate fitment confirmation. Our dedicated sample room keeps resistor blocks and related HVAC electrical parts organized by OE reference and application. This enables quick cross-checking of connector layout, mounting pattern, and structure, so you can reduce wrong-fit risk and shorten purchasing cycles.
Faster OE and application verification before bulk production
Quick photo support (connector & bracket details) for your internal approval
Sample availability for evaluation and comparison
Better accuracy for distributor listings and warehouse SKU management
Reduced returns caused by mismatched connectors or mounting holes
Send your OE number / reference number, photos of the original part (if available), and target quantity. We'll confirm match and advise the most suitable option for your market.
MOQ: 100 pcs for bulk orders. We support B2B export packaging suitable for importer/distributor warehousing.

Use a photo-based match: cross number (650179/CA1035) + terminal layout + mounting hole pattern. Mixed fleets often have similar-looking plates with different hole spacing.
In many aftermarket catalogs, CA1035 is used as a cross/reference for 650179 resistor plates. For bulk orders, confirm by comparing the terminal layout and plate outline.
Open-coil designs dissipate heat through airflow. If airflow is blocked (filters/debris) or the plate is installed out of position, the coil runs hotter and failure risk increases.
The top mistakes are choosing by cross number only while ignoring terminal orientation, hole spacing, and plate thickness. These details affect fitment across Freightliner/Navistar/New Holland applications.
Typical symptoms include missing low/medium fan speeds, only high speed, intermittent blower, or overheating marks on terminals in severe cases.
Check blower motor current draw, inspect the connector for loose/corroded terminals, and restore airflow (replace filters/clean ducts). High load and poor contact cause repeat failures.
Ask customers for a terminal-side photo and a mounting-hole photo. Tractor HVAC variants may differ by series and configuration, so photo match is faster than relying on model name alone.
Use quick QC: verify hole pattern with a template, check terminal tightness/alignment, and inspect coil symmetry/support stability. This reduces warehouse returns.
Prevent coil deformation: use inner protection to avoid pressure on coils and ensure terminals are protected. Carton marks should include 650179 / CA1035 for SKU control.
Provide cross number 650179 / CA1035, brand/series (e.g., Freightliner Century or New Holland T7.210), quantity (MOQ 100), destination/port, and photos of terminal side + mounting holes.
