Just indtalled new ac compressor. Ac works while driving. Coming to stop or at idke, ac blonks n compressor off. Radiator fan runs. Installed new ac relay fuse. Turn on ac to manual, but when slowing diwn or stop. Ac light blinks. Ac control- no error cide. Is it the rpm sensor in compressor? How can i verify it? Thanks
Also, I just looked at my fuse relay block and noticed several fuses that are the same part number as the compressor, swap a known good relay with your new compressor relay.

Referring to the new compressor...did you also replace the drier and expansion valve?
is it new or rebuilt and what brand?
did you vacuum the system?
how many ounces of Freon did you use?
did you use gauges or just a can gauge?
did you add oil to the system or did the compressor come with new oil?
Had shop check it out. He recharge everything. Still cuts out when rpm drops to idle. He is not a lexus ttech n doesnot know how to check the rpm sensor so basically he tells me to get ac replacemnt replacement
Our Camry was doing the blinking AC light. It would work fine as long as we were moving. But if it was hot outside and we came to a stop for a while (like at a traffic light), the ac would quit and the light would blink. They replaced the relay. I'll see today on the way home if it fixed it.
What is going through my mind is you saying the fans don't come on till after you stop. So that means it's coming on because of increased engine temperature. The fans should come on when the ac is on irregardless of you moving or sitting still. this would mean even while move the ac condenser isn't being cooled sufficiently. It's cooled enough to work while moving but not, Cool enough for maximum efficiency. This means as soon as you stop moving the temperature quickly rises to high for the ac to operate. Even with the fans kicking on it can't by itself compensate fast enough. So one needs to find out why the fans aren't turning on in conjunction with the ac turning on. That's my opinion on this situation.
No codes with obd n ac check. Radiator is working. I believe the problem is mu idle speed dropping to 600 rpm while drive at rest, causing the ac compeessor to shut off and ac llight blinking. When i start to drive (rpm above 800). Have to manual turn back ac to work again

What about if you are sitting idle and manually raise the rpm (via the gas pedal)? Will the compressor kick back on then and the ac light quit blinking?
vsc code came up. reset everything and has not return, idle speed better at 800 at park, then 600 when in drive gear. still ac blinks when idle 600. when i start moving, just turn off/on the ac to make it work again. otherwise no codes with scanner or ac panel.
