AC immediately stopped working

6 posts in this topic

So last night I was driving and the AC was working perfect and then I floored it (accelerated fast) for about 5 Seconds and the AC immediately stopped throwing cold air.

 

It turns on and it blows air but the air is hot. I checked to see if the heater works and it does it blows even hotter.

I mess with all the dials and settings and still nothing but very warm air.

 

It's unbearably hot and humid here in Miami Florida.

I don't know what it could be I'm hoping it's just a fuse or something because the car is at 40000 miles and I believe it is not under warranty anymore.

 

Does anyone have any idea what this could be or if Chevy may possibly fix this under one of their recalls ?

So tomorrow Tuesday June 6th would make a week since I've purchased the car from a private seller (original 1st owner)

We met at a bank and she completely paid off the car with the money I gave her to fulfill the lean but they still have not removed the electronic lien from the title so therefore I still have not transferred the title under my name.

The bank released the lein but the state/dmv/title said it takes about a week for it to be removed from the database.

Now the engine light came on so I took it to AutoZone to get a free diagnosis and the code PO128 came on saying something about coolant temperature running colder than normal levels.

 

I did look in the coolant reservoir tank and it was about 2 inches below the minimum amount and it was really sludgy/gunky and a little dark or dirty with what appears to be little balls/solidified coolant floating.

 

I added some coolant and smell the engine after a 30 minute drive and no odors or signs of overheating at all. Even the radiator fan shuts off after I shut off the vehicle. I will now google the code for further research.

But car was perfect and then AC stops working and 24 hours later the engine light came on. What's next.

I flushed out the coolant. How do I get the check engine light to turn off ?

Disconnect the battery for a good 15min.

Get a obd2 scanner, they are dirt cheap on amazon or ebay. Or go to a car parts store and ask them to clear it for you.

Some codes will turn the cel off after a certain number of ignition cycles without the issue.

Those floating little balls are most likely oil so I suspect head gasket or some oil getting into coolant..check oil level.
