window repair is not difficult. You’ll find the parts are probably reasonable. As for the air, I’d Google it and see what you come up with. I’ll wager it’s the clutch. It’ll cost you a few hours and a few bucks. But you might check the wiring to it first. You can probably hot wire it to see if it comes on. Then just rig a switch inside the car.
thank you, sweetie, but I’m a girl. I know nothing about cars. I just wanted to know if it’s worth putting any more money into this car. 1K seems outrageous.
