Thanks for the tip, very useful.
Keep rocking the tats pops! Nice video now this diyer can google diagram for my car and narrow down what component has failed.
Thanks. But most diy don t have ready access to the wiring diagrams.
Someone help. I have xterra fuses good. Has freon. A c compressor only works when i bypass the a c compressor relay. I tried a new relay and nothing worked
My compressor engages no problem, but the pressures on the gauges don t change at all!
What would cause a relay to work improperly. Sometimes it works sometimes it don t. If i run it direct it stays on. Peterbilt
Helpful. But i would have liked a demonstration of how to do it without the fancy tools rather than just a brief mention of the method at the end. I realize this is directed more at professional mechanics. But us diy guys can t all afford to spend money on diagnostic equipment we ll only use once a year or less.
Thanks for the video please i have question if the system empty i mean there is no foren in the system, is the clutch engage with compressor?
Hi! A dumb question maybe but, if there is no pressure on the low side, is there pressure on the high side? Thanx from sweden
Great video pete. Couple of questions on the solenoid side of the tool what does it mean when the bottom led glows red or green? If the bottom led light lights does it mean that thesolenoid circuit is working as it should and the pcm is commanding the relay on? Thanks
Thanks buddy, you really explained so so well. Learnt so much on that video.
Amen to the video enough said the rest of geeks who post videos need to watch this and learn thank you
I have a honda accord my a c compressor seems go into motion and start when i turn the a c on, but i recently filled it up with antifreeze so i can get a cool breeze from my a c vents but its just spitting out hot air. Any ideas on what could be going on?
One thing i did not see mentioned, was the iat sensor. Some manufacturers gm, if the inlet air temperature sensor is bad or unplugged, it will default to f. The ecm will say hey! I am not turning on the ac, it is freezing outside.
Great video! I have a cadillac deville i had a shop fill it with refrigerant now the clutch wont engage. Relay is good, low pressure switch read v with ignition forward but not running high pressure switch read v as well. When the clutch is jumped it blows super cold air. When the low pressure switch was disconnected the ac controls automatically disabled the ac to the off position. Any help would be appreciated.
I have a ford mustang. L v. Ac started blowing hot air. I checked freon and levels are fine. Compressor is not cycling when ac is on, but when i go to turn it manually it isn t frozen. Also checked both fuses for ac and they were fine as well. Still trying to figure out what s going on
Can you tell me where i can buy that neat little tool you used called the u activate tool
So i am able to measure voltage at the compressor connector, ruling out relay, fuses, pressure switch. So clutch coil is bad? What can i measure on the clutch coil pins to determine if it s good bad? What about a c clutch diode? Is the diode embedded in the clutch coil, or connector? Where can i measure to determine good bad a c clutch diode?
Wouldn t it be easier to use a multimeter and measure the voltage going into the compressor with and without the ac switch on? You get vdc with the ac off and vdc with the switch on. Would that not automatically rule out the switch relays without all of the other tests? I m asking because i currently am having problems with my ac clutch engaging on my b and don t have all of the other fancy equipment so i just tested the voltage going into the compressor.
