and it doesn't blow cold, whassup wid dat?

 

mine did it in Yellowstone the other morning... it was 34 degrees. That may have something to do with it. What do i know though

 

It's 85 degrees here. Black car. I need the a/c working bad.

 

prob low freon. Mine does same thing and when i checked it with a set of manifold gauges, its zero on both high and low.

 

you got it also to the OP when it get to low it will totally cut off to keep from you from replacing the comp. Go by auto zone and get that new can that is out now that any one can chg the system with.. Robert

 

Bad Outside Temp Sensor #10248401 $12.70+. Reads 34°, thus not allowing the A/C to come on.

Same thing happened to mine with flashing light.


Any DTC's?

Low freon I believe.

 

Low freon.

 

for andym1999 ;

The AC won't work at temps below about 35*-40* F. The AC light flashes if pressed when the air conditioning is not available. Makes sense to check the outside temp sensor & if it's OK, check the freon charge.

 

Isn't it still summer all over America? Low freon made mine flash.

If it is 40° somewhere I feel for you. We're still low 90's

 

i second the other folks, low freon and maybe the compressor is bad

 

First thing, does your temp read the correct outside temp after you have driven it a bit? If so, then , as already mentioned, you have and AC issue, low freon, leaking parts, etc, that will need to be check out. Yeh , you can put freon in it, but for how long? I would suggest getting the system checked out and fixed correctly.

 

Low freon.

 

If you have the AC on and the compressor isnt turning its porbably low on freon.

 

On my brothers Sierra the light was flashing and no cold air. Actually his wasn't blowing very much air at all. Ended up being a resistor for the blower motor and it works great now.

 

The flashing light is telling you the AC is not working so work through logically.

If the OAT is warmer than 35 degrees that means it should be working. An auto inhibit prevents it from operating at low temperatures. A bad OAT sensor will cause a similar symptom as the car thinks it cold but that will set a code.

Worth checking the codes next as an HVAC fault could cause it. Post any codes and we can find a procedure from the manual for you.

At that stage, if the codes are clear, I'd have the freon topped off because as the guys say, that will also cause the flashing light.

Mine was low on freon

 

My local a/c wrench plugged into a diognostic. He said i have only have half of the required pressure on the low side. My out temp sensor is reading well below the real temp.

 

Subscribing...


Just be glad your car did not read this when you get in.

My daily driver said this yesterday when I got in...

 

I remember those days in San Antonio. My record in Vegas was 126 degrees but I never got the picture. This was the best I did. Glad my AC worked that day



Nowadays it's more at the 32F end of the scale which is why I know the answer to the OPs question.
