AC not working. Any ideas?
Hey guys,
AC doesn’t turn on. I didn’t notice a click or a chance in engine/revs in any way, no subtle symptom of an AC compressor kicking in. I’ve played with all the settings and waited long enough, tried it in the highway and still nothing.
Anyone have ave any insight on this?
Thanks!

start with the basics and check the belt, make sure it didn't snap or is holding on by a thread. Next, check the relays, there are probably a few different ones within each fuse box. (inside car and under hood) You'll have to check the owners manual for the exact locations though. Without a click or any symptoms beforehand of blowing hot air or coming on and then going out randomly, the relays are a decent culprit. If all of this checks out ok, then strap in for the ride, bad compressor / blower fan in your future.

I had 6 or 7 servos going bad causing issues with vents opening or not opening. Repair under warranty other would have cost $3K. I was told its a common issues, and ECU had these error codes saved when it was scanned by the service tech.

A/C Not Working
Unusual for A/C not working? Is it not blowing Cold, or is it Not Blowing at all? Mind Farts, could be as simple as FAN got turned off accidentally...compressor won't CLIK in unless fan is on at least Speed 1....IF fan works, but not blowing cold then likely a stone or something may have put a tiny hole in A/C line..(VERY fragile), again, if no refrigerant, Compressor won't CLIK.
- CHECK Fan ON/OFF?
- If fan on, may need a line test by a technician to look for leaks.
- Lexus/Toyota have the MOST reliable A/C units in the World, so hopefully, just something simple.

Mine is blowing hot and I can’t here a click. I’d have to pop the hood and have someone turn on the AC from the inside to confirm this but from what I recall I can’t hear it.
I have my appointment booked for the 22nd. I’ll have answers then! Hope it’s a quick fix and hopefully it’s under warranty.

I just experienced this issue today on my 2015, driver's side is blowing hot air while passenger side is blowing cold air. The driver's side air is hot! Adjusting the temp does nothing.

Looks like there are seven different servo part #s, depends on which DTCs are being triggered in TIS Tech Stream.

Thanks for attaching the file from the service manual. I was about to pull up this exact document today. It's disappointing there isn't a recall on this since it's relatively common. I'll hook up a scan tool and see what I can find and report back.

For me luckily a simple A/C module reprogramming resolved the issue, car was ready to go within a few hours.
