Hi Marc-
The sound you are hearing MAY be the electric fuel pump in the tank that is supplying gasoline to the motor.
It should not be making a noise when normal, but may be needing replacement shortly.
Hope this helps!

SOURCE: 1990 lincoln town car trunk motor will work when releasing trunk

All you have to do is bring it in and it takes 2 minutes...to make it like a regular manual car trunk...they tap the part where it closes and it works just like a regular trunk. Much better because I always thought I'd get my hand caught in the automatic. One of the guys at the Service Center did it for me in 2 minutes for free:)) Don't get a new motor just make it manual. Plus the trunk open switch still works as usual.

SOURCE: Convertible Top Wont move but motor sounds.

If what you are trying does not fix your problem and the motor runs, then crack the line loose at each top cylinder, the cylinder is equipped with a check valve inside it that may be stuck, releive pressure and try again to operate, if possible check pressure at the pump.

SOURCE: convertible top won't go back up, can you help?

IT is probably a fuse. Does it work at all? my mustang had a busted cylinder and only 1 side would go up. If it doesnt work at all then check your fuses. With no manual you will have to use a flashlight and shine on them and see if one is blown. IF they all look good then I would go buy a testlight for about $10 and manually check the fuses for power. It oculd be the motor, however that will cost you several hundred dollars and that is if you install it yourself.

Testimonial: "Thank you so much. I have a friend checking fuses now, not sure. The top would still work to go down, but would give me a problem to go back up.THANKS"

SOURCE: Convertible top goes down and won't come back up.

You are probably low on fluid.
Behind the rear seat is the motor/pump/reservoir.
With the top down, fill the reservoir till it overflows with ATF. Cycle the system a few times. Repeat till the reservoir will accept no more fluid.
Look for leaking lines or cylinders. The fluid must have gone someplace.
Always replace lines and or cylinders in pairs.

SOURCE: 2006 Mustang convertible with only set of keys locked in trunk.

Convertibles are easy, just cut the top ,, just kidding. Call the dealer and get the key code, I would think the locksmith would have done that already?

My 1993 Ford Mustang convertible won't go up.But the motor is coming on.Also it will go down thou


There must be a hydraulic fluid leak somewhere. Check to see if there is oil filler cap on your hydraulic pump located in the trunk compartment. Fill if necessary with just enough fluid to raise the top. The reason it won't go up is cause it is lacking pressure from the low fluid

How do you open the top of a convertible mustang


If motor does not run when the switch is pressed then check your fuses, the switch and the connector at the top motor to see if it is getting power. Remember the car should be in park with the emergency brake on. The key switch has to be in the run position. There are two release levers that need to be pulled out and they are located above both of the sun visors. Press the switch just to the left of the emergency break lever. If you can hear the motor running and the top still doesn't go down, check for the smell of hydraulic fluid in the trunk. It could leaking from the cylinders that pull the top down and push it up. If one or both will not hold pressure. Replace cylinders if bad.

I own a 1990 Ford Mustang LX. The drivers window will not function at all. However, the passenger window will, but slowly. What is the recomended fix for this problem? I thought maybe a fuse, but if that...


Sounds like a bad motor to me and the other one is on it's way out. It does happen over time.
You can find them fairly cheap at a junkyard.
If you take off your door panel you can see them inside the door frame on each door. They are fairly easy to replace yourself. Just make sure that the window is all the way up before you take it off track to put in the new motor so you wont need to re-adjust it after you get the motor in.
