My 1994 convertible top isn’t working. It isn’t the parking brake - I had that bypassed, so it isn’t necessary to apply the brake to lower the top. I checked the fuses in the passenger side and in the boot. They seem fine. When I press the top button, there is no whirring sound from the motor and the back windows don’t go down.

Can anyone suggest what could be wrong? I’m guessing the top switch in the center console has gone bad.

Thank you

 

Switch would be easy to check, just bypass the wires.

How about the relays? Those are where the pump is.

And I'm assuming the pump isn't set to manual.

Other than fuses, the car needs to know that the car is in Park, and not in any gear, including neutral.

 

Thank you for your help!

I’ll bypass the wires on the switch and check it. I’ve been wanting a new switch anyway because it’s faded.

The top hasn’t been bypassed.

How would I know which relay could be bad? There are several. I don’t even know how to test that a relay is good or bad.
