Why does ac for Hyundai azera 2007 only works on drivers side?

You have the VIN#. Call the dealer. They are the only ones that can tell you your options on that car.

Lock all the doors. open it with a fob or the driver side key. then get in and turn the ignition on.

Possible transmission gear noise, but would need to hear it to confirm.

check the fuse .

I have a 2012 Azera and had the same trunk lock problem -- there is a security cutout switch located in the top center of the glove box opening which can be tripped if the glove box contents stick up over the lip of the opening. This switch disables the truck release on the dash and on the remote fob. On earlier Azera's the switch is located on the left side of the glovebox opening.

check the battery cables, the clock reset indicates you lost power to the whole electrical system.

Check the fuse--it may be out. Fuse box is on the side of the dash (when the driver's side door is open) next to the steering wheel. Pull hard--the fuse names are on the panel door you just pulled out. Fuse puller is in the "engine room" according to the manual for a 2006 Hyundai Azera Limited, though I haven't been able to find the "engine room", yet.

The answer is in your glovebox. There is a trunk lock-out button on the top left. It is designed to prevent access to the trunk if using a valet (or anyone else driving your car). Go to your glovebox and press the button. The trunk should now work as intended.

Try it with the engine not running. If it works fine, the problem is RF interference. If you are using platinum spark plugs instead of the old copper resistor plugs, it can cause this.
