If the car's air conditioning is in automatic mode, the two central air vents may not blow air. Switching to manual mode will allow air to flow. There is a knob next to the air vent with white markings; adjust the knob so that all markings are visible on the outside. The reasons for the car's air conditioning not blowing air include the following: 1. Check if the air vent switch is properly connected and if there is any short circuit. 2. Inspect the air conditioning fuse to see if it has blown. 3. Check if the air vents are blocked. 4. Verify if the air conditioning motor fan is functioning properly. 5. Examine the vehicle's power distribution, including the battery.

Where is the thermostat located in the Nissan Sylphy?

The thermostat of the Sylphy is installed at the connection between the lower hose and the engine block. The thermostat is a valve used to control the flow path of the coolant, serving as an automatic temperature-regulating device. It typically contains a temperature-sensing component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction. The steps for replacing the thermostat are as follows: 1. Turn off the engine, open the front hood, and disconnect the negative terminal of the battery. This is to prevent the electric fan from suddenly operating during the work, which could cause personal injury. 2. Remove the plastic cover outside the timing belt. 3. The position of the generator may affect the replacement of the thermostat, so the generator assembly needs to be removed. 4. Place a water-catching tray under the vehicle, then prepare to remove the hose and wait for the antifreeze to drain completely. 5. Remove the faulty thermostat and install the new one. After installing the thermostat, apply a layer of sealant to the hose connection. 6. Reinstall the removed hose, generator, and timing belt cover to their original positions. Reconnect the negative terminal of the battery, add new antifreeze, and then start the engine for testing.
