Product Description
A blower motor resistor regulates current to the HVAC blower motor, enabling multiple fan speeds. Heavy-duty truck resistor plates operate under higher continuous load and heat. Open-coil designs are commonly used because airflow from 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.

Match three visual points: (a) mounting plate outline + hole pattern, (b) terminal positions, and (c) coil layout/height. For open-coil resistor plates, plate geometry determines whether the coil sits in the HVAC airflow path.
In most aftermarket catalogs, 33-3195 is used as a reference number for the 1696836C1 blower motor resistor plate family. For bulk purchasing, always confirm by photo matching of terminals and hole pattern.
The resistor plate creates different resistance steps through multiple coil paths. The HVAC switch selects different paths to deliver multiple blower speed stages, which is why terminal layout matters for correct speed mapping.
Open-coil resistors rely on HVAC duct airflow to remove heat. If airflow is blocked (dirty cabin filter, debris in duct) or the plate is mounted incorrectly, the coil runs hotter and may discolor terminals or fail early.
The top mistakes are:
Selecting by OE only but ignoring terminal orientation
Assuming all plates share the same hole spacing
Missing coil height differences that affect airflow placement
To avoid returns, confirm OE + terminal layout + hole pattern.
Ask for any two of these three items: OE 1696836C1, clear photo of terminal side, photo showing mounting holes. This is faster than asking for VIN and works well for mixed fleet maintenance orders.
For coil plates, you often see heat discoloration on spade terminals, warped coil supports, or intermittent low speeds due to poor contact. Module-style controllers more often fail without visible coil damage.
Focus on root causes:
Check blower motor current draw (worn motor = high load)
Replace burnt connector housing / loose terminals
Restore airflow (replace cabin filter, clean duct debris)
This reduces overheating and extends resistor plate life.
Recommended QC for resistor plates:
Verify hole pattern consistency with a simple go/no-go template
Check terminal tightness and plating condition
Inspect coil symmetry and support stability
These checks are fast and reduce warehouse returns.
Avoid coil deformation during transit. Use inner protection to prevent coils from being crushed, keep terminal caps/spacing, and ensure cartons are tightly packed. For bulk orders, we recommend carton marks with OE 1696836C1 / Ref 33-3195 for SKU control.
