Originally the top was very slow to go up. Most of the time it would time out and I would turn the key off and back on and finish the cycle. It would retract halfway then almost just drop into the resting position. I lifted up the rear hoop and pulled the motor. Some fluid was in the motor housing 1/2" at the most, no corrosion, no rust on the motor. The bottom and side sound insulation was damp, but not the top. However the emergency release cable wasn't engaged with the lever on the motor. Took it apart and the release nipple was sticking into the housing. Cleaned it all up.
Here's the fun part. Now the header clamp and unclamp run momentarily. It takes 4/5 button pushes to clamp and unclamp. The roof motor runs briefly at the end of the unclamp. 2 seconds. Fluid is 2/3 full in reservoir, hydraulic lines are on the correct post, 11,12 on top 13,14 on bottom. Emergency release handle is in correct position, shelf switch is engaged. I know that works if I take out the shelf it goes orange on the button. If I connect the motor to the battery it runs but no roof movement. Clamps are unlatched. Any suggestions?

Update: The header motor and gears are working fine. They had gotten out of sync with the window cycle. I've been disconnecting the battery and while working on the roof and it needed the windows to cycle for the header motor to run correctly. It's the roof opening/closing that is the problem. At this point I have the motor out of the car. When connected to a battery the 12/14 port will push fluid out in a good stream. I reversed the wires expecting fluid would pump out of 11/13 port. But nothing came out of that port. A couple more drops came out of the 12/14 port but not much. So I need to see if I can find info on how this pump should be working.
