A/c problems

Hi all, my a/c has stopped working, I brought the car in November 2020
The owner then said he had the a/c recharged with gas, but now it not working
The green light is on but I donít hear a click or any Rev difference, does the Yaris
2007 have relays for me to check? Also is my a/c a clutchless type as it looks like
It always engaged even when the a/c is turned off, I think maybe it shuts down when low on gas, any help would be great before I take it to a garage,
Thank you

it is highly possible that you have a refrigerant leak somewhere depleting your refrigerant hence the compressor wont run as a safeguard. It could be in the o-rings or joints or it could be in the evaporator which is hidden under the dash and need to take it off by a qualified AC technician. It can easily be tested by using manifold gauges. Low pressure side must be anywhere near 25-30psi dependent on ambient temperature, also need to check the HP side.

Okay I did think I might have a leak somewhere as the original owner mentioned to me a few times he’s had the a/c re-gassed, so it’s the a/c clutch supposed to always be engaged even when turned off in the car?
Thank you

Our compressor has an internal clutch. Visually, it appears that the clutch is always engaged.
You need to get a pressure test done as a first step. If you're low, then you have a leak. If pressure is fine, then your next likely point of failure is the pressure sensor. Failure of that component is rare but is exactly what shut my a/c down.
