For some reason I thought the AC compressor came with only enough oil for the unit itself but that would make sense if it has 7oz like you stated. That might be where you went wrong. Some compressors come filled with enough oil for the entire system, and some come dry. What would be the best approa...

A blinking A/C-switch light on a Toyota product means that a difference in RPM exists between the engine and compressor. The blinking light further indicates that the compressor's drive belt is slipping and that it is momentarily seizing or has completely seized. The question is, why? From your des...

Hello, I have a 2001 Lexus GS300 I replaced the compressor, expansion valve, condensor, and pressure switch with Denso products. I added 1.3oz of oil to the system for the new condensor and the compressor already came pre-oiled. Flushed, vacuumed and recharged with 600g of freon per the service manu...

After one hour, the HP and LP sides should equalize. If they don't, the cause is usually a defective metering device—in this instance, the TXV—and/or a blockage someplace. Presuming a full charge of refrigerant, if you're seeing only 100 PSI on the high side at an ambient temperature of 76°F, it do...

I think the comp is NG, assuming it actually has refrigerant still inside what is your country I think any sniffer from a so-called big box store would do for the random user And just to clarify, the pressure reading do not change on the gauges after I shut it off. They remain the same ass 100 and ...

I think the comp is NG, assuming it actually has refrigerant still inside what is your country I think any sniffer from a so-called big box store would do for the random user It does still have refrigerant as it spits a bunch when I remove high Side line. United States. I was just asking if there w...

You may be correct. The hi side pressure you give leans toward that. However, you have done the testing at 650RPM. We test auto AC by having the RPM at 1500-1800. Repeat your testing at that RPM. A compressor does very little work, if any, at such a low RPM Also, how many miles on the car? You are ...

Hello! Thank you for the response! I ran outside and redid the test at 1500 RPM The low side only dropped by 5psi and the high remained the same. The car has 216,000 miles but the engine has 65k miles. It's a 2JZGTE VVTi JDM engine from a Toyota Aristo of same year. It's a direct swapped and the ac ...

Hello, Hello, 2001 Lexus GS300 Bought this car recently and the AC wasn't working from the beginning. Decided to pull vaccum using a shops machine, which it held and also charged it per specification. My friend did it as a favor so i just left quickly due to the late night. The clutch engages and st...
