1) The manual control valve bleeds gas to control the crankcase pressure to change the differential pressure across the underside of the piston verses the piston top which in turn changes the swashplate cam angle or stroke and refrigerant mass flow. Early versions had internal filters which would s...

American Market versions of this vehicle use a variable displacement compressor. So no thermostat is needed. https://ackits.net/wp-content/uploads/14-0919NEW.jpg Hi Tim, Thank you for sharing this info. Regarding the US altima it does have a mechanical control valve https://i.ebayimg.com/images/g/v...

Couldn't make them customers wait till I find an answer online so had to install manual thermostat inside evaporator to cycle them compressor. Anyone got an idea how to solve the issue of freezing ac line on altima because I couldn't find the factory thermostat anywhere.

Hi, I own an auto workshop in UAE and do alot of AC repair on many cars. One of the problem I can't really find its source is the newer altima ac system. Many customers complain of hot air from ac vent to find that the compressor is jammed or got no pressure at all. Ac line full of black burnt oil a...

Always a tricky test. Because the coil & diode are in parallel, the resistance through the coil is the same both directions. But the diode has a 0.5v drop one direction, and is effectively an open circuit the other direction. A DMM will not display the very small change when switching polarity....

The black band on the diode should face the ground. Hi Dougflas, you are right about black band (cathode) should be connected to ground but that would only help me in case i want to replace the burnt diode which was completely toasted and crumbled. These diodes are hard to access and I have to cut ...

Hello everyone, I have a problem with my Dodge challanger 2015 with AC problem as it was not cooling. Took it to a mechanic, a friend of mine, to fix it and he doubted the clutch coil is the problem. He disassemble the A/C and took the compressor out to test it. Not sure why he wanted to test the co...
