My car won't start unless I get a jump. After my car is turned off, a ticking/clicking noise is coming from inside my radio area and it drains my battery.

I can unplug the box but when that is done, the car will not start at all unless it is plug back in. Can you tell me what the box is?

Recently noticed that the automatic climate control on my 2006 Sonata stopped working. The temperature readout still shows desired interior temperature but nothing happens when dial is turned all the way up or down. When in manual mode, the heater fan will adjust faster or slower when dial is turned so I still get heat/ac but only by dialing manually. If I switch to automatic mode, the fan will operate in whatever setting it was in when in manual mode. Could this be a defective heater blend door?

Past 2 months, my Hyundai Sonata, 2005 has a lower idle at 700rpm, very rough idle and shaking.
