I am an Idiot, yet very Brilliant!

Oh man, I am not so smart, yet brilliant! We have two cars, the car Chris and I bought when we first got married and the car his grandparents gave us. The car his grandparent gave us is a green Buick that has been really used over the years. His dad use to take this car to and from work everyday, has eatin multiple meals in this car, spilled pop in it and etc. It works just fine, do not get me wrong, there are just some things i would like to change about it. 1. The window if rolled down, will sometimes not roll up. 2. It sucks to drive in the winter 3. It tends to blow hot air for air conditioning. Sometime ago in the winter, i went to order food for Chris and I at Arctic Circle. I arrived and my window would not roll down. I tried everything, punching the buttons, restarting the car, screaming at it, hitting it, i mean everything. I finally had to step out the car to order my food and to receive my food/ pay. I went home and continued my day. The following day i had to go pick up a friend to go to a wedding shower. It was then, that all of the kicking and screaming finally worked, my window went down; I started the car and the window went down. I am assuming it got jammed, all of a sudden it unjammed itself and got jammed again. Chris was at work and i had no idea what to do. I started the car, let it run for a bit (like 30minutes), then i ducked tape the window shut with garbage bags to keep the hot air in, nothing! Nothing worked. Chris's dad had to come down the next day to fix it because i was useless! BUT!! i resorted to what everyman does..... ducktape, which makes me brilliant.
