Fan Belt?

Today I was driving and all was fine, then my air was not coming out like it has been, and i look down my hand was in the H. So I turn the car around to get home, I was not to far from home.

I am guessing this is some kind of belt that cause this to happen?

Also When I parked the car, I could not roll the windows up, would all this be connected to the same thing? Or Am I looking for a few diffrent problmes?

check the belts on the pulley of your engine. there should be 3 belts. if one of these is missing or loose you can buy a belt at a auto store and DIY or take it to a shop. it would take you less then 2 hours to replace the belt(s) if you have the right equipment. i recently put an underdrive pulley on my J30 and that only took me 2:30 hours and i had to take the radiator out. you dont have to take the radiator out to replace the belts. if you want to know more on how to put belts on just PM me.

You might be looking for a couple of things. Check your belts. If they are good then make sure ur not leaking any fluid anywhere. My J30 recently started leaking and as a result it over heated on me. I had to go in a and replace my water pump which is a pain in the ass. as far as your windows i dont really have an answer. Hope that helps some

I had to rpelace all the belts.

the fan belt broke, but in chaing that belt they seen all the other belts were worn, so we replaced them all.
