Re: Evaporator temperature sensor placement

I did a bit of searching on how to read the ac gauges and what the readings mean and stuff. I also ordered a manifold gauge online, and it arrived yesterday. Ill also be ordering a vacuum pump if i have extra cash just in case i would need it some time in the future :D There is a new problem with th...

Re: Purging With Nitrogen ???

The ac shops here in my place always purge the system with nitrogen before vacuuming the system to charge. The reason, i dont know. But i know that vacuuming the system is what removes the moisture.

Re: Evaporator temperature sensor placement

Sorry for the late update, i was testing the ac of the car. @cusser. Yeah, his thermometer broke days before i brought the car. Ive been testing the car since the evaporator was replaced with the "good used original". All has been good so far. Only the air feels very humid every time the c...

Re: Evaporator temperature sensor placement

The tech meant evaporator. Anyway, i have an update: I brought the car to the other shop to try out his original used evaporator... The first thing the guy from the other shop noticed when he took off my replacement evaporator is the placement of the TXV sensing bulb. He told me its pointing in the ...

Re: Evaporator temperature sensor placement

UPDATE: I took the car to another shop for a second opinion, the theory of the guy in this shop is the replacement evaporator is made of thicker materials than the original one, reducing the heat transfer. He suggested replacing the evaporator again with an original. He is selling me a used one in g...

Re: Evaporator temperature sensor placement

To explain my first post more: the thermistor was placed in different locations in the evaporator, those different locations caused the compressor to cycle at different vent temps. With the probe in the upper right side, the ac would cycle when the vent temps reach 25 degrees celsius. With the probe...

Re: Evaporator temperature sensor placement

Regardless of whether the compressor is the variable-displacement or fixed-displacement type, in this car it has a clutch, which de-energizes or remains energized when it shouldn't. The question is, why does it do that? We know that the compressor clutch is getting voltage. But then the voltage tur...

Re: Evaporator temperature sensor placement

a 30 minute vacuum after a system opening is not long enough to pull out moisture and leftover flushing vapors esp in temps below 85 degrees and often times the vac pumps used are too weak to pull deep enough giving higher pressures and weaker performance plus contaminates the oil and desiccant res...

Re: Evaporator temperature sensor placement

No, the ac button light does not blink. The ac relay has also been replaced recently. Havent tried another thermistor, but we will try a known good used one. The compressor was replaced a year ago with a brand new original nissan unit, i also had the condenser replaced with a good quality replacemen...

Re: Evaporator temperature sensor placement

There are no mufflers in any of the lines. The compressor was also removed from the car and was drained of all oil. And yes, the oil the tech used is PAG-100. The tech also tried jumping the high pressure switch thinking it might be defective but there was no change. The compressor would still turn ...
