Hello there, I am Cam. I am licensed automotive technician with more than 18 years experience. As an expert on the site, I only have access to your question. Any billing questions or concerns would require a customer service specialist. A couple things before we get going; - I am around most days but not every minute of every day. If you reply while I am offline, I will respond when I am next online. -I am a Firefighter/Paramedic which might require me to drop and run at any time without warning. If this happens, I will reply as soon as I am able to. -The website will automatically offer a phone call. Some times they are beneficial, sometimes not. I am sorry to hear you are having troubles with your vehicle. While I am looking at your question, can you tell me who I have the pleasure of assisting today? Was the AC working properly before this?

charla and yes perfectly
Automotive Expert
Also is there any warnings on the dash Charla? You said the [AC compressor](/topics-ac-compressor-chevy/) is working?

no warning and yes compressor is working
Automotive Expert
Is the air coming out of the dash hot or just not cold?

hotwe checked under the dash and the thing that moves back and forth that changes the temperature is working
Automotive Expert
Ok, sounds like the heater is stuck. First check all fuses. There are fuse blocks in either side of the dash and under the hood. After that if the fuses are good, lets try taking the battery off and leave it disconnected for 30 minutes. After that see if the system works. If not then the next step is to scan for codes.

ok we have disconnected the battery. he had already checked every fuse. we tried to scan for codes but his machine was not working right I dont think
Automotive Expert
Ok, did you try disconnecting the Amp? Its possible the wiring he connected to is not correct.

he didhe has installed several so I know it is not incorrect wiring
Automotive Expert
Understood. Is it both sides that are hot or just one?

both
Automotive Expert
Do the other functions of the heater work correctly? Does it change mode?

it is we checked that and changing it to feet or defrost
Automotive Expert
Ok, has the scanner you are using normally work on your truck?

we have never had to use it before the truck only has 30000 miles and never an issue
Automotive Expert
OK, if everything is connected, we know the amp and wiring is good, then we need codes. You have ruled out everything we can check without the codes.

ok so I know auto zone and places like that cannot find anything unless the [engine](/topics-engine-chevy/) light is on
Automotive Expert
That is because they are using reader meant for engine codes only. We need a code reader that can read all codes or a shop type scanner. For the average owner, a bluedriver is the one I suggest.

ok so if keeping the battery off for thirty minutes does not change anything we will take it to the Chevrolet house
Automotive Expert
I think that is what is next.

ok thank you
Automotive Expert
You are most welcome.

Still not sure what you need?
