Is there a button on the shifter that allows to activate or deactivate over drive? Does the OD light flash, and do you so the rpm raise at all? Nine times out of ten a over drive problem is the first symptom of the transmission in the vehicle acting up and eventually blowing.

The light flashes whenever the electronic transmission control unit senses a fault in the system controls of the transmission. You need the computer tested by the dealer or a shop with a special tester.

First I suggest confirm what fuse blowing there and waht circuit and edevices are controled, check some wire broken or bad ground in the line and switch (if have one there).

Keep us updated.

engine light keeps comeing on n sometimes the battery light comes on my 94 lexus es 300 wat does tat me

The OD light flashing indicates a code has been stored in the trans control module. If the speedo stopped working that could be the whole problem, the most common thing for the speedo quitting is the sensor on the top of the rear end housing, that causes 99% of the speedo failure. If that sensor isn't working the ABS light would be on too (if equiped) I would try that first or get a code pulled out of the computer and I could give you a more complete answer. -Jared

Its a faulty sensor switch on your brakes master cylinder. It leaks brake fluid into the wires that are plugged into it and causes a short in the circuit, resulting in a blown fuse that controls the AC, odometer, speedometer, cruise control, and ABS light to come on. This problem can also cause a fire. The fire can occur even when the vehicle is off. To fix this problem go to this URL - http://www.fordwindstarrecall.info/

I had this problem a few years ago. Get it checked out right away. I didn't and I ended up having to replace my transmission.

Its weird but I had a fuse blow out awhile back that is the same fuse that works the cab lights when you open the doors. When this fuse went out it also made it shift odd and hard when it did shift. Since it is only intermittent in your case, It may just be a weak fuse.
