Overdrive Fuse Popping
 

the number 11 fuse (i think) which is the electronic fourth gear fuse keeps popping and making my car not go into overdrive. any suggestions? i have a 93 240 wagon

Well, if the fuse keeps popping, that's a fair indicator the circuit pulls too much juice. A short circuit is the most common reason. Check under the car by the transmission and see if you can find the overdrive solenoid. There's a wire that comes out the top. Follow it and see if there's a break or bad insulation. Under the car is a hostile environ for wiring. The o.d. relay is behind the glovebox and the wiring goes down under the passenger carpet to the drive tunnel and up inside the shifter cover to the o.d. button. Get a service manual and you can follow the diagram as to where the wiring goes.

thanks dude! i will give that a try today!
