2004 Camry AC light blinking

[CarLuver]

Helped a freind change compressor on 04 camry with manual ac controls . swapped compressor and did a vaccum and charge by weight . works great with 40 degree temp from the vents .

Every once in while the A/C light will blink and A/C will shut down . a quick on /off press and it restarts . According to the net, this means there is an issue in the A/C system . locked compressor . low charge most common . none of these seem to apply .

The one thing i i do recall is it had this issue before we swapped the compressor . i have changed the relay . its so inttermitent that can't reproduce it at will. No codes . A/C when it works , which is 99% of the time , is ice cold.

I think its an electrical or ecm issue . not sure how to test the ecm . Any suggestions on what else to do?

I had a first gen Camry from the 80s where the AC light would blink, and it would shut off, if you drove over a deep puddle.

I had an '03 that had the blinking light. An A/C service solved it. Hmmmm

Try swapping out the A/C clutch relay (again) in the underhood fuse box.

aftermarket compressor or OE/denso? lots of aftermarket compressors have iffy lock sensors

aftermarket . it was already doing it before changing the compressor . changed compressor due to noisy clutch. its so intermitent that there is no way to make it happen on demand

 

[CarLuver]

it already had the updated relay in it . i put a new one in there just in case

Is the clutch still operating when the light is flashing? If not tap the clutch face with a plastic hammer, it it immediately engages the shims may need to be adjusted, check the air gap.
