简介
2000款 奇骏 的空调有时候制冷有时候不制冷。 空调只有当压缩机当离合器接合时,空调系统会制冷,但离合器结合但快速退出时,空调只会从冷风转为暖风。
你所需要的
-
-
热敏电阻连接器位于手套箱下方。 您可以看到白色连接器在下方悬着。
-
热敏电阻的作用是保持蒸发器不会被冻住。 通过热敏电阻测量温度来决定是否让蒸发器在40华氏度时让蒸发器启动除霜。
-
找到您的空调压缩机。 压缩机离合器位于中心区域。 如果离合器接合,中心区域将转动。 热敏电阻决定离合器的结合与分离,以防止蒸发器被冻结。
-
这些是要完成本指南所需要的工具。
-
-
-
测试打着车打开空调后的热敏电阻。
-
使用电压表(设置为直流伏特(DC Volts)),绿色/橙色线将带有保险盒内保保险丝#29的电瓶电压(约13.5vdc)。
-
蓝线将从交流控制组件的电池接地。
-
最重要的线是蓝色和黑色线。 当热敏电阻打开(温度高于45华氏度)时,电压表将显示小于0.5伏。 当热敏电阻关闭(温度低于40华氏度)时,它将显示额定的4-5伏特。
-
在初始运行时,蒸发器的温度将高于45度,电压表读数应小于0.5伏。 当蒸发器的温度低于40华氏度时,电压表将读取4-5伏特,使空调压缩机关闭。 这样可以防止蒸发器冻结。
-
当您首次打开交流电源时,如果您的热敏电阻读数为4-5伏,则热敏电阻出现故障,需要更换。

Excellent information. My 2003 Xterra was acting up with the AC compressor kicking off and on when the vehicle got up to temperature. One mechanic told me the compressor was knocking and ready to fail. I found out that it was simply overcharged with Freon after a high pressure AC hose replacement. It has worked fine for two years now after getting the Freon right.
Article by Doug Layne was the answer to my 2000 Nissan Frontier Crew Cab. The Thermo Amplifier was the cause of my problem. A/C works like new. Also make sure you clean inside the unit. I have no idea how so much dirt got into the unit. Must be poor design.
Thanks Doug from another Doug

What was yours doing and what did you do to fix it.I just got mine 01 and the compressor is working but not cooling much.please help.
What was yours doing.my compressor is working and the garage charged it but not getting cold.they said they thouhht it was the expansion valve.what do you think
In step 6, part of the sentence is cut off, what should it say: "They provided a hole for you to mount the new bracket. ( I guess they al"
