2014 Tundra - blinking AC light...tried most things

things ive tried so far

-pressure on high and low is GOOD
-compressor TURNS ON when jumped with a wire and shows good pressure + cold ac
-compressor turns on for 2 seconds when turned on through relay then disconnects
-tried bypassing the high pressure sensor
-tried putting a magnet to the compressor switch on the compressor

what am i missing? i know on Camry's you can put a magnet on that flow sensor...is this one different? in either case i tried that

is this a bad compressor? basically it will run when relay jumped....and we tried several relays

 

Relay!!!!
Get a new one from toyota. Don't buy cheap auto parts store one

I had this exact problem on my 2007 tundra from new. It would blink. Sometimes ac worked sometimes didn't. I went 5 years without ac.

Turned out to be the relay. I had even changed it with auto parts store relays. It sometimes worked, sometimes didn't.

Then I bought the oem one from toyota. It worked perfect till I sold the truck.

My 19 tundra never gave me this issue

 

tried 2 other relays ...still same result compressor comes on for 2 seconds then off forever

can this be a flow control sensor issue?

 

A VOM is your friend here. Did you put a meter on the control side of the relay and check for voltage drop? I’d start there.

 

You need to look at the pressures in the lines, the head pressure could be climbing too high after the compressor kicks on so it auto shuts it off for safety. Generally means there’s a blockage
