A/C Issue?

Hey all,

I was driving from work and the A/C button started to blink and warm air started blowing out of the vent. I've had this happen once before and i turned it off and on which fixed the problem then, but now when i tried that it just went back to blowing hot air. I did this about 3 times until i left it for about 20 mins when the A/C started working again. Anyone else have this happen? I have a 2015, with about 32k miles.

 

Maybe blower resistor? Costs about $50 and super easy to replace but mine didn't got until 150k miles I never noticed blinking light but it started the same way, blowing hot for a few minutes then cold, next time it wouldn't kick back to cold

 

A low refrigerant charge can cause the symptom you describe...

 

Compressor magnet is taking a shit. Replace the compressor

 

thanks for the help guys.

you mean that really expensive part?

 

Start off small.... check resistor first

 

You are still under warranty, get thee to your dealer while it's on THEIR dime.

 

The resistor for the blower will not cause a blinking LED for the AC.

The blinking LED on the AC means that the Magnetic clutch was commanded to be energized and the rotational sensor at the compressor pulley did not sense a rotation.

Causes could be any of these:
A defective clutch coil.
A locked up compressor.
Defective MG CLT Relay.
Blown IG1 No2 Fuse.
Defective AC Amplifier.
Wiring Open in the clutch circuit.

That being said if I had a warranty I would let the dealer handle it for free.

 

I should be under warranty still, ill contact the dealership and get it checked out. Thanks for the advice everyone. I'll let you guys know what the problem was once they find it for any future cases.
