AC not working - Toyota Yaris Forums

srm73 · 06-18-2020, 08:37 PM

Hi all. My 2009 Yaris AC was working perfectly last summer. I tried turning it on a few days ago and it wont blow any cold air. First thought that came to my mind that the AC gas must've leaked out. But today I tested it again and it seems like the AC is not even kicking in. May be the compressor is not coming on as I dont feel any change in engine rpms or overall engine load.

Any where I can look before making the conclusion that the compressor has gone bad? Any fuses I can check? Thanks in advance everyone.

There may be some info in my thread that could be helpful; specifically the diagnostic tables.

Thank you 06YarisRS;830654 for the reply. I went to my mechanic this morning and have my AC checked. He says that there is some electric issue. I have to leave the car with him and he is going to spend some time on it to figure out what electric problem it is. He says the fuses are ok. Now, I didnt have time to leave the car with him today. Probably will plan it for some other time. But meanwhile, I was thinking if I could try to diagnose the problem my self, and was thinking the ( Relay ) might be bad. Wondering if someone could guide me a little bit as to 1st where is it located and how to check if its faulty or not? Other then that, any other comments or help will be appreciated.

Probably just like mine a few years back. Pressure sensor failed and needed replacing.
