1972 Cutlass Top not working

Hello. Today was hot out and I drove the car 50 miles with the top down. I get home and press the up button but no response.
I am not good with cars. What can I do to fix this?

The convertible top's pump is between the rear seat and trunk compartment. Go in the trunk, close to the rear seat, and have someone operate the top switch both directions, and listen to see if you hear the pump motor run. Also listen for the top relay clicking.

That will tell you if the electrics and hydraulics of the top are functioning.

If the pump starts both directions, it may be low on hydraulic fluid. There's a specific procedure to add fluid, but since you're not comfortable working on cars, you're going to need some help. Post your general location and someone might be able to help. Hydraulically operated tops are probably going to be beyond the capabilities of most modern repair shops- they probably don't have anyone who's ever seen one.

I've had quite a hectic couple months and finally getting back to fixing this car. My location is Lincoln, Ne. I'm bummed to hear that most modern repair shops aren't able to fix. Thank you for the reply. If anyone has any suggestions or anyone around my area I would appreciate any help.

Did you do the basic testing that Rocketraider suggested? Pretty simple test. Do it and report your findings. That way we can help you. These things are not that complicated. You have a pump in the trunk, wiring to it from a switch on the dash, hoses, and two cylinders. Failure points are hydraulic fluid leaking, switch failures, pump failures. I just put new hoses and cylinders on my 72.
