I finally got everything working. I went over all the problems related to a system this old with the owner and she plans to replace everything with parts from Hydraulic Tops. Dorman has the replacement pull down motor which I found the OEM one has three cracks in the plastic housing. It would be a smart move to replace all of the system before it springs a leak on the interior. The pumps on the average last about 15 years so this one is about due. The car is back with the owner now. Thanks for all the help.
