Santana air conditioning relay is the No. 13 relay located at the upper left corner, specifically the 53rd 4-pin relay. The new Santana air conditioning relay is on the circuit board behind the fuse box. The function of the air conditioning relay includes compressor start relay, fan start relay, heating switch relay, defrost switch relay, and electric auxiliary heating switch relay. Reasons why the car air conditioner has no airflow: 1. Blower motor failure: The car blower motor is a crucial component for air conditioning airflow. If the air conditioning compressor fails during use, the car air conditioner will definitely not produce airflow. 2. Clogged air filter: The air filter is a significant and common reason for no airflow. During operation, the car air conditioner absorbs many impurities from the air. 3. Control system failure: Possible issues include the air door, air conditioning computer, or control switch malfunction. Control system switches generally do not fail. It is recommended that car owners visit a 4S shop for inspection, as this will simplify the troubleshooting process.

Can I Transfer to Another Driving School Without Completing the Course?

It is possible to transfer to another driving school without completing the course. Below are the details regarding transferring driving schools: 1. Transfer Details: Theoretically, you can transfer to another driving school without completing the course, and it will not affect the subjects you have already passed. However, in practice, you may encounter many issues, such as difficulty in scheduling appointments with other driving schools. 2. Considerations: Transferring to another driving school requires negotiation with the originally enrolled driving school, as their consent is needed to transfer your records. Additionally, since the student's records are filed with the vehicle management department through the original driving school at the time of enrollment, and these records are registered under the name of the original driving school, some vehicle management offices do not offer a record transfer service as part of their procedures.

Will Insurance Cover a Car Flooded in a Flood?

If you have purchased water wading insurance, the insurance company will compensate. Here is additional information: 1. Engine water ingress: General losses from a flooded car can be compensated within the limits of the vehicle damage insurance, but most insurance companies' vehicle damage insurance policies include exemption clauses for 'losses caused by engine water ingress.' Compensation for damages caused by engine water ingress can be complicated and may even be denied. 2. Water wading insurance: Water wading insurance is an additional coverage that cannot be purchased separately and must be bought alongside vehicle damage insurance. If you have already purchased vehicle damage insurance, you can add 'water wading insurance' at the insurance company. This insurance has a 20% deductible rate, but if you purchase the no-deductible option for this coverage, you can receive 100% compensation.

What is the difference between engines that use 95-octane and 92-octane gasoline?

The difference between engines that use 95-octane and 92-octane gasoline lies in the compression ratio: engines using 95-octane gasoline have a compression ratio between 10.0 and 11.5, while those using 92-octane gasoline have a compression ratio below 9.5. The choice of gasoline octane rating should match or be compatible with the design of the car's engine. Vehicles with higher engine compression ratios should opt for gasoline with a higher octane rating. 95-octane gasoline, which has a higher octane value, is suitable for engines with higher compression ratios. In such engines, as the operating speed increases, the ignition timing in the cylinder advances. When the speed reaches a critical point, the air-fuel mixture in the cylinder may ignite prematurely before the spark plug fires, a phenomenon known as knocking. Increasing the octane rating of the gasoline effectively enhances its anti-knock properties.
