The symptoms you describe, such as the flashing amber light on the defrost knob, loss of airflow, and clicking sounds when opening the driver's door, suggest a potential issue with the blend door or the blend door actuator in your HVAC (Heating, Ventilation, and Air Conditioning) system. The blend door is responsible for directing the airflow between the various vents, including the defrost vents, dash vents, and floor vents. Here are some steps you can take to further diagnose and address the issue: 1. **Blend Door Actuator Inspection:** The clicking sound you hear when opening the driver's door might be related to the blend door actuator. The actuator is a motorized component that controls the position of the blend door. Check if the clicking sound is coming from the actuator. If you can access it, inspect for any visible damage or obstructions. 2. **Check for Obstructions:** Sometimes, foreign objects or debris can obstruct the movement of the blend door. Check for any visible obstructions in the HVAC ducts. 3. **Perform HVAC Self-Test (if available):** Some vehicles allow you to perform a self-test on the HVAC system. Refer to your vehicle's service manual for instructions on how to initiate a self-test. This may provide additional diagnostic information. 4. **Inspect Wiring and Connectors:** Check the wiring and connectors associated with the blend door actuator and the HVAC control module. Ensure there are no loose connections, damaged wires, or corroded connectors. 5. **Professional Diagnosis:** If the issue persists after the above checks, it may be advisable to seek professional diagnosis from a qualified mechanic or a Jeep dealership. They can use diagnostic tools to retrieve fault codes and perform more advanced testing on the HVAC system. 6. **Consider Blend Door Calibration:** In some cases, the blend door may need recalibration after a control module replacement. Refer to your vehicle's service manual for instructions on how to calibrate the blend door system. Calibration procedures can vary between vehicle models. It's worth noting that even though you replaced the control module, the issue may still be related to the blend door actuator or the blend door itself. The clicking sound when opening the door suggests that there may be a connection. Remember to consult your vehicle's service manual for model-specific information and procedures. If you're not comfortable with the diagnostic process, seeking assistance from a professional mechanic is recommended.

Have you checked the connectors in the wiring harnesses for the ABS unit and associated components for water intrusion or corrosion? The codes that you've posted (details below) all point to a poor electrical connection in the circuit(s) or an open or short in the circuit(s). That could be either due to corrosion, liquid intrusion, a wiring harness rubbing against something hot or something that vibrates and has damaged the wiring. If the wiring and connections are all intact and there are no opens, shorts to power or shorts to ground, the next think to look at would be the modules and/or sensors to make sure they're operating within spec. U1003 Possible Causes: *Faulty Anti-lock Brake System (ABS) *Module Anti-lock Brake System (ABS) *Module harness is open or shorted Anti-lock Brake System (ABS) *Module circuit poor electrical connection The Diagnostic Trouble Code (DTC) sets if the Anti-lock Brake System (ABS) Module fails to receive bus messages from the Dynamic Sensor for approximately 150 ms. ----- C0020-1c Possible Causes: *Faulty Anti-Lock Brake System (ABS) *Control Module Faulty Hydraulic Control Unit (HCU) *Hydraulic Control Unit (HCU) harness is open or shorted Hydraulic Control Unit *(HCU) circuit poor electrical connection The Hydraulic Control Unit (HCU) consists of a valve body, pump motor, and inlet/outlets for the brake lines. The combined HCU and Antilock Brake System (ABS) module is located forward of the master cylinder. The Anti-Lock Brake System (ABS) Module monitors the ABS Pump Motor. The ABS Module sets the OBDII code when the ABS Pump Motor is not to factory specifications. ------ U0125 Possible Causes: *Faulty Dynamics Sensor Dynamics Sensor *Harness is open or shorted Dynamics *Sensor circuit poor electrical connection The Diagnostic Trouble Code (DTC) sets if the Anti-Lock Brakes System (ABS) Module fails to receive bus messages from the Dynamics Sensor.

The 2005 Jeep Grand Cherokee Laredo 3.7L typically has two oxygen (O2) sensors. One is located upstream (before the catalytic converter), often referred to as the pre-cat or upstream sensor, and the other is located downstream (after the catalytic converter), known as the post-cat or downstream sensor. In many cases, the upstream and downstream sensors are not the same and serve different purposes in monitoring and optimizing the air-fuel mixture and emissions.

To use the 3M Quick Fix Adhesive Kit to glue on a Jeep emblem, follow these steps: Clean the Surface: Ensure that the surface where you'll attach the emblem is clean, dry, and free from any dirt, grease, or residue. Use a mild detergent or rubbing alcohol to clean the area thoroughly. Let it dry completely. Prepare the Emblem and Surface: If the Jeep emblem has an existing adhesive residue, carefully remove it using a suitable adhesive remover or rubbing alcohol. Wipe it clean and dry. Prepare the Quick Fix Adhesive: Open the 3M Quick Fix Adhesive Kit. Typically, these kits consist of a dual adhesive syringe that combines resin and hardener. Follow the instructions provided in the kit to properly mix the adhesive components. Some kits require you to press and release the plunger to mix the resin and hardener thoroughly. Apply the Adhesive: Squeeze a small amount of the mixed adhesive onto the back of the Jeep emblem or onto the surface where you'll place the emblem. Apply the adhesive sparingly but cover the necessary area evenly. Attach the Emblem: Carefully place the Jeep emblem onto the prepared surface. Ensure it's aligned correctly and press it firmly into place. Hold in Position: Hold the emblem in place with consistent pressure for the time recommended in the 3M Quick Fix Adhesive Kit instructions. This allows the adhesive to bond properly. Allow Cure Time: Follow the curing time recommended by the adhesive kit instructions. It may take several hours for the adhesive to fully set and cure, so avoid moving or disturbing the emblem during this time. Clean Up: Clean any excess adhesive around the edges of the emblem using a suitable solvent or rubbing alcohol before it fully hardens. Remember to refer to the specific instructions provided with the 3M Quick Fix Adhesive Kit as different kits may have variations in their application procedures and curing times. Additionally, ensure you're working in a well-ventilated area and follow safety precautions as advised by the product instructions.

Get a man to drop the car off and to go back and pay (with your card) and pick it up. No, the O2 sensors are likely to be fine is there are no codes. If the mixture is running lean, it can cause overheating, but the catalytic converter is made to run hot.
