My air vents won't blow air and when this happens sometimes my cruse won't work. And other times my automatic lights won't go out. My major concern is I don't have air at this time

I have been told my battery is bad but the car still starts, so i'm wondering if that could be the problem, the battery just isn't strong enough to run everything. I plan on buying a new one monday

If the battery can start the car it can run the blower. I would check power and ground @ the blower

@ the blower motor with key on or engine running there shoud be 12 volts on one side of the connecter with it un pluged and the blower on a speed. If there is 12 volts plug it in and add a ground to the other side and see if it runs. The most comin problem with this system is the blower resistor it has the relay built in to it. The blower is located behind the right side of the dash the fues are in the fuse block on the right side of the dash. Check all fueses first.

It isn't the blower motor it works fine but the a/c compressor doesn't kick on or the cooling fan for the motor won't work. It really don't make sense to me cause why wouldn't the cruise or the automatic lights work either.

You have a lot of things going on. We need to start somewhere. I would start with the blower or compressor or cooling fan and work my way back. All the problems may or may not be related
