✅A/C Light Blinking Fix, Weird Loud Noise, AC Not Blowing Cold Air Anymore Quick Fix DIY Review

Clutch Fan Relay part number 90987-02028 12V made by DENSO
Standard AC Relay part number 35874 made by FourSeasons

If you engine is making a weird noise intermittently, AC blowing hot air or not cold, and AC button light is blinking then it could be any easy relay replacement. If this does not fix your AC problem then you might want a shop to look at it and check your cooling system. Your AC system could be low on freon, bad RMP speed sensor to the compressor, AC compressor could be bad, could have a leak somewhere, bad condenser or evaporator coil.

I love YouTube because people like you sharing, I just have the exact problem like you have now. Will try it tomorrow!

Thank you for this video! I just had this problem on the way home in 102 degree heat. I hope this is the fix!

My Tacoma ac only blinks about 30 seconds after I first turn it on. Turning the ac off and on again fixes it for the duration of the drive. My freon is full, belts are new and relay is new. What else could it be?

[Stalicone]

I have these exact symptoms. Flashing A/C light, the same noise…everything. The replacement relay did not mitigate the issue. Suggestions for next steps?

Awesome, thx for posting. I have a similar issue & looking at other videos showing replacement of clutch and/or compressor is a huge task in comparison. Draining & replenishing looks like something I don't really want to tackle, too many special tools. I'm going to check my relay first. ;-)

I’m having the same problem is there anything g else this would be I changed the relay and nothing

[adrianwilliams]

I’ve completely changed everything on my 2010 Lexus IS350 at this point I’m just going to get rid of it, because nothing has seemed to work. The AC light stays lit for less than a min and start blinking.

Mine blinked the other day and stopped cooling. After shutting it off and then back on, it started working again. Not sure what happened....

[ashleynichols]

Do u think that's what is wrong with mine. Blinking light loud squealing noise hot air

[ohheyitsdezz]

my car the ac works for about 30 minutes when the car is up to temp the light shuts off and the air goes hot it’ll keep coming back on and shutting off and i hear i whining noise when it’s on when i accelerate

[zombieman]

the traverse i am looking at buying has no a/c it flashes the a/c lights a couple of times when you try to hit the extra cooling button but the light goes right back off. and i heard no weird noises from it but it doesnt seem to have great airflow either way? could lower airflow be a sign of a bad compressor or could it be something as easy as a relay? the air blows somewhat but not cold

[danikachildress-yzoz]

What if the ac IA blowing cold but all the lights are blinking still and your car dies?

[mariopyzik]

Thanx a lot .. that was very helpful!!

[adembujer-xoyq]

Excuse me, what is the size of the amp for the relay?

[patrickhamilton]

I pulled mine out and put it back in working again probably just corroded
