AC and heater dont work??

[Chaddycakes21]

My AC and my heater both do not work at all. Even the light thats on the AC button doesnt light up anymore. Anyone have any ideas? Also the defrost button and light dont work as well.

First off, check your fuses under the driver dash. Most likely a blown one there. I don't have my manual with me or I'd give you numbers Let me know if I can help further.

Your AC might be out of refrigerant. Buy a recharge system at Napa, Autozone, Pepboys, etc.

checked the fuses no blown ones???

The AC wont work period. Its not that it just blows warm air.
I have no idea what it could be.

If you turn the fan on, does it blow air? If not, there's something wrong. If it blows hot air when the a/c is on, you probably just need it recharged. Are you looking at the fuse box under the steering wheel or the fuse box under the hood?

Agreed, do you have any air coming out of the vents at all?

I'm having the same problem, my a/c or heater doesn't work. However, at higher speeds the heater starts to work. Like the faster I go, the more it works.

A small amount of heat or cool air will come out of the vents when i turn it to vent and turn it from heat to cold. Do you guys think this could be alternator related. When i turn my signals there is a slight dim in the dash light. They kinda flick on and off a little bit with the blinker.

I had my alt. tested today. Came out good. The guy at autozone told me it could because of the way the wires are connected to my battery. Could be a loose connection. Im going to check it out and get back.

I went to O'reilys and asked if I can borrow their all in one gauge and refegirant charger. Anyway, connect the hose to the low port, underneath the throttle body. You don't have to keep the car running. The gauge should read automatically. And on the label of the can should tell you what your charge is compared to your numbers. If you got a charge, check your compressor. Look for belt condition. Turn the car on right quick and listen for the compressor clutch spinning. Ok, done for now.

Im such an idot. I found out what it was....Finally. The reason is because someone asked me today how i checked the fuses. So i told them with a light tester. Then they asked if i tested both sides of the fuse and that my friends was what i wasn't doing. So i went outside and properly checked the fuses and the heater relay fuse was blown as well as the back up 10 amp fuse?? Thanks for all the help anyways guys.
