What causes for the ac air to change from the front vents to the dash defroster vent when you accelerate on a 1993 Ford van?
Low vacuum. When you push down on the accelerator, vacuum decreases. Your Blower doors use vacuum to change positions from floor to vent to defrost. Have a vacuum test done on the vehicle. You may have a vacuum leak, or this may be a sign the engine is getting weak.(Low compression, Leaking valves, etc.)

How do you troubleshoot the rear window defroster for a 1989 Toyota 4Runner?
First things first, make sure that the wires are connected at BOTH sides of the rear window for the defroster. There needs to be a path for the burrent to flow, so both need to be connected. If not, you can purcahse kits to re attach them, or if you are handy enough...solder it yourself. If they are connected, push the button that turn the defroster on...if you hear a click or a change in the sound of the engine (like its under load) then the defroster is working, but you have a connection problem between the device up front and the wires on the window. hope that helps

93 ford escort wagon when you turn the defroster on the air blows out the vents instead of on the the top of the dashboard?
Because it's not a defroster button! It's just the symbol for ventilating the air into the car. It shoudln't be called a defroster since defrosting is meant by heating up the coils that you see at the back of the car. I'm pretty no car has wires in the front!

They are bars which mount on the rear axle, under the leaf springs of a rwd car or truck. As you accelerate the torque will cause the axle rotate up at the front. The traction bar has a bump stop at the the front that when this happens contacts the front mount of the leaf spring. This contact causes the wheels to be driven into the pavement(more taction).
