Passenger side window/lock doesn't work, check engine light came on

What is your question?

It's been 2 years in 2014, my passenger side window/lock just stop working.. I guess it's just me and never cared but when friends sit in back it would be nice to let them have window down.. Is this a issue wth Nitro's? I own it .. I guess I should get it fixed took to Firestone tech worked on truck 2 hours couldn't find problem I guess now I'm go have to bite he bullet an pay $125.. So dodge can check it out I have replaced my 2 front struts/brakes rotors/muffler/sway link bar/serpentine belt 3 times/and just had water pump put ok Friday 7/29/16.. Now check engine light came on , it's an 07 basic model 3.7 engine, I got it when they 1st came out.. Do not have larger engine .. Had 3 recalls just one issue after another.. What could be the issue now catalytic converter?.. So sick of all these issues, truck paid off may have to just get a newer vehicle and advice?
