Civic 2013 Ex-L Ac compressor switching on and off

[diego gonzalez]

Hello all could you please help me with this problem:

when I turn on my ac the compressor it's switching on and off too quick, it make the on and off cycle in about 10 sec, but only when I set the temperature setpoint on 20°c or hotter, if I select colder setpoint the compressor runs continuoisly but don't trow cold air, the ac control module doesnt' have code's, and the refrigerant seems to be ok filled

here's a video with the fail: View: https://www.youtube.com/watch?v=XLfG4ejib2A

Do you have a service manual that states what the high/low are supposed to be at in your model?

There are a lot of factors, including ambient air temps.

Start with this for static pressure - engine off and high/low side equalized


Then use this chart, its from Honda

thanks for the information, I will take a look and see if the pressures are okay

if pressures are fine, how can I determine if there's a problem with the condenser?


the ac control module has a input sensor display mode (attached images) maybe that could help


this is the electric circuit.....

these are my readings with 38°C

I'm low on refrigerant jeje, should I only fill it or should I emty the system and make a vacuum?




I don't have the service manual, where can I fin it'



thanks!

I’ve always just filled mine. Grab a can of something like this at amazon/Walmart/auto store and fill till the pressure is appropriate.

unless you have the equipment to pull a vacuum, just filling it is fine.

After you fill it up to the right pressures, turn off the car and let it sit for a while. then take a readings on static pressures. A few cars I have done have been a bit high on freon after the charge. From my experience on a few cars, using the static pressures works well and every car I have done this on have had freezing cold ac
