I plan on getting another 240 soon but it has numerous problem. He was honest enough to give me a list with all the problems that he knows.new brakes neededgear ratio need to be tunednew A/C belt neededfuses for interiorneed new driver side power window motor

Most of the things are no biggy except the gear ratio, fuses for interior, and power window motor. How easy is it to replace the power window motor since I've never touched one.For the fuses I guess i can just replace them with my current 240. He also said something about the parking brake not bitting hard and I need to adjust I need to fix/adjust it. How easy to do it? thanks

ive heard that a $25 regulator usually fixes the power window problems. check the fuse in the engine compartment too. otherwise installing the power window assembly isnt too difficult from what ive heard but getting it to crank up and down without power is near impossible.

gumby may be right about the regulator. Ask the guy if he knows for sure that it's the motor. There's a big difference between a $25 regulator and a $120 motor. Whether motor or regulator though, it will be an easy task.

By the way, what model is this 240?

regulator? What does that look like? Another problem is the speedo ain't working; the needle is all the way passed 115mph and just stay there. He said the light on there isn't workin either. I guess that what he meant when he said the fuses aren't working. I have all the parts I need for replacement b/c I have another 240 sitting in my garage. Why not use it as a parts car ^_^. He wouldn't even know if the power motor is out or the regulator..

Window motor should be easy to diagnose? Turn key to run, don't start it or you won't hear it. Put ear near the back-bottom portion of the door panel. Press the power window switch. Do you hear a clicking-clunking noise? Yes=motor out. No=Regulator out.

Someone tell us, is that black box there a relay or the regulator? Wait, doesn't the regulator control both windows? I may have just answered my own question. Probally the motor or relay.

Anyway, if you replace the motor, WATCH OUT!, if the window is in the up position it will slide down as soon as you have unscrewed the last screw. You could wind up breaking the window or worse, chopping off you fingers. Simple answer is just get a buddy to hold it up while you swap the motors out.

AC belt and fuses should not be hard at all.

No, no. The regulator is the mechanical assembly that moves the window up and down. The motor is attached to the regulator, and thus powers it.

See the picture below:

-red - approximate location of motor (this is inside the door- regulator must be removed to access)-yellow - approximate outline of regulator (this is also inside the door - window must be removed in order to remove this)-green - 4 nuts that secure the window to the regulator-blue - 4 nuts that secure the regulator to the door-purple - wiring harness for the motor

You will first have to remove the door panel, obviously.Then you can reattach the window switches and put the window in about the location mine is in.You are then able to remove the four nuts securing the window (green)CAREFULLY AND GENTLY lift the window up and work it out the opening at the top of the door. The stopper thingy on the rear end of the window gave me particular trouble.Once the window is clear, disconnect the motor's wiring harness and detach it from the door (purple) and remove the four nuts securing the regulator (blue)At this point, the regulator is finally free. Maneuver it through the top of the door just like the window. I had a much easier time with the regulator than the window.

Installation is of course a simple reversal. However, I will mention that the window may not be properly aligned when you finish. This is why the holes for all the bolts are so big. You should be able to loosen and adjust them to straighten the window.

I didn't have to remove the regulator (your yellow outline) to change my motor. I just reached my hand around and unscrewed it from the door. It looked like someone had messed with it before because the metal was already bent to get at the screws on the motor. Not the best job but it worked.

What is the thing that I circled in white on your picture then? All I know is that it clicks very loudly when I push the window switch. It still worked before I changed out my window motor.

One more thing. That gear right to the left of where you circled in red is the motor. The gear comes off with the motor and makes the glass slide down when it is removed. Had I known how to get the regulator out at the time, I would have. I need new glass because my regulator has somehow put some scratches in it, so your explanation has helped me a bit. Just bought me a parts car that has nice glass.

This car sounds like it will be more trouble than it's worth. It obviously has some electrical problems that you might never get fixed. Just know what you are getting yourself into. Good luck.

I checked today and I don't think it's the motor based from what you guys have told me. There were no sound watsoever when I tested it. So now I guess it's the regulator. BTW: If it's a fuse problem can you tell me where to find it and which fuse? thanks a lot guys
