First determine if the air conditioner compressor is working after 60 km / h. If the compressor does not work, check the air conditioner circuit, including checking the air conditioner compressor, relay, pressure switch, water temperature switch and air conditioner controller. If the compressor is working normally, Refrigeration, it is possible that the compressor is constantly working, resulting in expansion valve freezing, and thus not cooling. We have to understand when the car reaches a certain temperature (such as 5 ℃), the compressor, the controller cut off the compressor control power to prevent expansion valve freeze, the controller mainly based on the evaporator outlet temperature switch to Cut off the compressor power supply, so the most convenient way to check the temperature control switch is: unplug the thermostat switch connector, and then check whether the compressor work. If the compressor is still working, the air conditioning controller may be damaged, or the position of the temperature control switch and air conditioner inlet air temperature sensor is incorrect. Otherwise, the temperature switch is damaged. Regal 2.0 run-in period Notes Q: Can introduce some Regal 2.0 run-in period considerations? A: Regal 2.0 running-in period Note: ①try to avoid rapid acceleration, fierce step on the accelerator, speed limit, under normal circumstances do not exceed the speed of 100 km / h, try to use medium-speed; ② After starting the engine, it is best to make the engine idling A few minutes, let the water temperature rose to normal working temperature, and then start the vehicle; ③ usually, observe whether there is leakage, leakage, leakage situation; ④ driving 3000 km, should be replaced oil, oil grid, .

POLO for widening normal increase in fuel consumption Q: My love: POLO hand wave 1.4 l just changed 195.55.15 (Goodyear) wide tires, the entire original air-conditioning fuel consumption 8L / 100KM, is fuel consumption 10L / 100KM, may I ask normal ? A: POLO handwave 1.4 liters after the replacement of wide tires, the fuel consumption is larger than the original normal, because the use of wide tires, and the contact area increases, the resistance increases, the corresponding increase in some fuel consumption is normal. Introduction to explosion-proof solar film Q: Please introduce two affordable explosion-proof membrane? A: The early solar film is only the role of shading, now appear explosion-proof solar film, known as the foreign metal film. That "explosion" is not a bullet-proof effect, but because the car after the accident, the glass burst, affixed to the glass of this layer of film to prevent the splash around the glass to reduce the harm to human body; the other hand can be heat insulation, UV and so on. Currently on the market better performance in all aspects of 3M, Ray Ban, but the higher prices; more other brands, cited in 2 cases, such as Garley, Sun Bao, cheaper prices.
