I was thinking of changing plugs but could it be something else?

2004 Sonata Heater/AC blower will not turn off

B4 I bought it I took it to an AAA garage for their pre-purchase inspection. They told me a few things that needed to be done. I had some concerns about the front end suspension and steering and asked them to check for frame damage or any evidence of an accident. None were reported by them. Now I find out that the entire car had been repainted by MAACO in 09. Car fax comes up clean for accidents. Any one know where else I can go to find out why this car was repainted??

I took it b4 I bought it to a mechanic who said a few things needed to be done rack and pinion need to be replace eventually some leaking He also said the inner tie rods needed to be replace sooner. He suggested an oil change and tire rotation which I have done. I notice after driving it that to me it runs a little rough so I thought I should do spark plugs and wires + fuel filter or the general maintenance suggested by mfg at 75K What do you think ?

My '04 Sonata fails emissions due to the readiness monitors, specifically the catalyst and the oxygen sensor. It has failed 6 or 7 tests over 3 1/2 months and 4,000 miles of mostly highway driving. I replaced the battery last October and the first failed test came in early November. I've been to 3 shops and called a dealership, and they all give the same advice to "just keep driving and the drive cycle should complete." But no luck so far. The check engine light has never come on, and it drives just fine. Having read what is required for a typical drive cycle, I should have completed many in my normal course.

Prior to replacing the battery, the car would require a jump frequently for things I felt shouldn't drain it. Such as having the hazard lights on less than 10 minutes, or the radio on while parked for about 15 minutes after just driving for about an hour.

Any advice would be appreciated.
