Tridon Air Conditioning Resistor TFR178, 4-PIN

The Tridon Air Conditioning Resistor, part number TFR178, is a climate control component supplied as a single unit and identified r conditioning resistor. It carries a 4-pin connection and is listed under Tridon as an AC component for vehicle cooling systems.

This part is sold each and has a stated weight of 0.07kg. For buyers matching a replacement resistor, the part number TFR178 is the key identifier to compare against the original unit, along with the 4-pin layout and the application details provided for HOLDEN and HOLDEN RODEO.

A one-year warranty is listed for this item. As with any climate control electrical component, the safest approach is to confirm the connector style, pin count, and part number before ordering, especially when replacing a failed resistor rather than upgrading a complete system.

Application and Buying Notes

Before ordering, compare the original resistor against TFR178 and check that the connector is a 4-pin style. That combination is the most practical first check when replacing an air conditioning resistor, because the wrong pin count or plug arrangement will stop the part from matching the existing harness.

The listed fitment references HOLDEN and HOLDEN RODEO, with sample applications shown for HOLDEN RODEO 2003 through 2008. If your vehicle sits within that range, it is still worth confirming the exact part number on the old resistor or in the vehicle’s parts information before purchase.

At 0.07kg, this is a small electrical component rather than a bulky climate control assembly. That makes visual comparison straightforward: check the shape, mounting points, and connector side-by-side with the removed part. The one-year warranty applies to the supplied item, but it does not replace the need to confirm the vehicle application first.

If the existing resistor has failed, symptoms can vary depending on the vehicle’s climate control setup, so it is best not to assume interchange from appearance alone. The safest buying decision is to match TFR178, verify the 4 pins, and confirm the HOLDEN or HOLDEN RODEO application details shown here before fitting.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number TFR178 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Tridon Air Conditioning Resistor. Part number TFR178 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TFR178, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning resistor in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN RODEO, HOLDEN RODEO 2003, HOLDEN RODEO 2004, HOLDEN RODEO 2005. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number TFR178, the 4-pin connector layout, and the HOLDEN / HOLDEN RODEO application details before purchase. If your original part differs in plug style, pin count, or mounting arrangement, do not rely on appearance alone.
