i have a 90 5.0 mustang when i hit the top button it just clicks any ideas.

Where is the clicking sound coming from, the switch or ??? If it is the switch, pull the switch and verify all wires have a good mechanical connection. If so, use a multimeter to verify the input and output. If it is a motor, again, make sure all wires have a good mechanical connection and use your multimeter to verify the input/output.

the clicking is coming from somwhere around the pump.

i'd say the hydraulic pump is shot.

It might be the motor that drives the pump. I tried to look up the cost of the whole unit and came up with a price of $530 for a new one. You still want to verify you are getting power to the motor. If you are, take a look at the unit and see if you can separate the motor from the pump. You might be able to get a part number off the motor and just buy it. If not, it's probably time to hit the salvage yards.

Interestingly I found this on a site called http://www.all-parts.com/diagnostics...nvertible.html

Q: I have a convertible... When you hit the switch to open or shut the top, it just clicks - no action. Where should I look??


A: Power to the switch??.... Then power from the switch??.... Then power into the motor??? If yes to all three, buy a new motor
