2004 Hyundai Sonata Questions

I have a 2004 Hyundai Sonata and I am having problems steering. The Power steering is good. All the belts are still on the car, yet when I begin a turn, it becomes very hard to steer. What could be wrong with it?

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. When I remove the indash where the air vents and radio is located, I can see that the noise is coming from a silver box. 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?

Will it keep it from running?

After it blew off and shattered on the road while driving on highway 59 in SE Kansas Dec.26, we noticed rust on the seal--moisture must have seeped in over the years. We took it to a car glass shop. They couldn't replace it. We can't drive with a roof, so where/how/who can replace it? And how much will it cost?

It would also stall out when i would put gas

This was my reading when it went through Emissions.

The car wash a jerk but continue to stay on then there will be a clicking sound under my dashboard in the car will shut off. It happens at least 3 times a day.

When I start the car from a cold start the ABS & Hand Brake Light goes off. After a warm start the ABS & Hand brake light stays on.

I am looking for my first car, and have today been out trying a Honda
Accord 2003 (90,000miles, 4cyl) and a Hyundai Sonata 2004
(88,000miles, 6cyl). Both at the price of $3,500. The Honda seemed more
smooth in its drive, however, it needs a windshield repair due to cracks
and a new back light. The Hyundai felt heavier and not as smooth as the
Honda, but looked almost as new + had a more trustworthy seller. Any
suggestions on which one might be better to consider?

Hyundai Sonata 2004 Gls 2.7 v6

It has over 100,000 on it. Minimal maintenance.
Sears just checked it out, ran an engine cleaner and replaced some fluids. Battery is old but it's not due to battery. Sometimes it restarts, but now it will not restart.

Replaced my radiator, which was cracked. I think the crack was because the fans are not working.

emissions. Monitor catalyst, and Monitor 02 readiness not ready.

Its a 2004 sonata with 6 cylinders please help
