3.3 Critical Fitment Confirmation
To ensure compatibility, verify your vehicle meets
all of the following criteria:
- Right-Hand Drive (RHD): Must be a Thailand-market RHD variant (left-hand drive Chinese domestic models are not compatible).
- OEM Number Match: Check your old resistor for 8114120-CD01 or 8114120-AW01 (located on the resistor housing).
- Connector & Mounting: 3-pin electrical connector + 2 mounting screws (standard for all listed models).
4. Step-by-Step Installation Guide (DIY-Friendly)
4.1 Tools Required
- Cross-head screwdriver (Phillips #2)
- Plastic trim removal tool (optional, for glove box clips)
- Dielectric grease (recommended, for connector protection)
- Work light (for visibility in tight spaces)
4.2 Safety First
- Turn off the ignition and remove the key from the ignition switch.
- Disconnect the negative battery terminal using a wrench. Wait 5–10 minutes to allow the vehicle’s capacitors to discharge (prevents short circuits or electrical shock).
4.3 Installation Steps (Changan RHD Models)
Step 1: Access the Resistor Location
- The blower motor resistor is located behind the passenger-side glove box (RHD: passenger side = left side of the vehicle).
- To access it:
- Squeeze the two plastic clips on the sides of the glove box and pull it open fully.
- Release the glove box stops (if equipped) to let it hang down, or remove it completely by unscrewing the retaining screws (1–2 screws on each side).
Step 2: Remove the Old Resistor
- Locate the resistor module: a small rectangular component with a 3-pin wiring harness connected to it, mounted on the HVAC duct.
- Disconnect the wiring harness: Press the locking tab on the connector and pull it straight out (do not yank or twist the wires).
- Remove the mounting screws: Use the cross-head screwdriver to unscrew the two 6mm screws holding the resistor to the duct.
- Extract the old resistor: Gently pull it out of the duct opening, noting its orientation (the metal cooling fins should face into the duct for proper heat dissipation).
Step 3: Prepare the New Resistor
- Compare the new resistor with the old one: Ensure the connector, mounting holes, and cooling fin orientation are identical.
- Apply dielectric grease (optional but recommended): Lightly coat the connector pins and the resistor’s mounting flange to prevent corrosion and improve electrical conductivity.
Step 4: Install the New Resistor
- Insert the new resistor into the duct opening, aligning it with the mounting holes (match the orientation of the old resistor).
- Secure with mounting screws: Tighten the two screws snugly—do not over-tighten (this can crack the plastic housing or strip the threads).
- Reconnect the wiring harness: Push the connector onto the resistor’s pins until you hear a “click” (confirms the locking tab is engaged). Gently tug on the harness to ensure it is secure.
Step 5: Reassemble & Test
- Reinstall the glove box: Secure it with the retaining screws or clips, ensuring it closes and latches properly.
- Reconnect the battery: Reattach the negative battery terminal and tighten the wrench securely.
- Function Test (critical):
- Start the vehicle’s engine.
- Turn on the HVAC system and test all fan speed levels (1, 2, 3, 4/MAX) in both A/C and heater modes.
- Confirm smooth airflow at each speed—no gaps or abnormal noise.
- Run the system for 5–10 minutes and check for burning smells or overheating (if detected, turn off the system and recheck the installation).
4.4 Professional Tip
If the wiring harness connector shows
melting, discoloration, or damage, replace it immediately (a damaged connector can cause the new resistor to fail prematurely). Use Changan’s OEM replacement connector (part number: 3725010-M01) for best results.
5. Quality & Compatibility Assurance
- OEM-Matched Specifications: Engineered to meet Changan’s original tolerances for resistance, current handling, and heat dissipation.
- Durable Construction: Aluminum alloy cooling fins + high-temperature PCB resistors resist vibration and extreme heat (up to 180°C).
- Thailand Market-Tested: Validated for RHD Changan models sold in Thailand, ensuring compliance with local climate and driving conditions.
6. Frequently Asked Questions (FAQs)
Q1: Will this resistor fit left-hand drive (LHD) Changan models?
A: No. This resistor is
only for RHD variants (Thailand market). LHD models use a different mounting bracket and wiring orientation.
Q2: Can I use 8114120-AW01 instead of 8114120-CD01?
A: Yes. Both numbers are 100% interchangeable for all listed Thailand RHD models.
Q3: What are the signs of a faulty blower motor resistor?
A: Common symptoms include:
- Only high-speed fan operation (low/medium speeds do not work).
- No airflow from the HVAC vents (all speeds).
- Intermittent fan operation (cuts in/out while driving).
- Burning smell from the dashboard (indicates overheating).
Q4: Do I need professional installation?
A: No. This is a DIY-friendly repair—most users complete it in 20–30 minutes with basic tools. Follow the step-by-step guide for best results.
