If indeed it is your pump, check ebay for used parts. Here is a link....


I purchased from this vendor. All went well... Make him a cash offer.... Lots of self help for install on the net. Make sure your vert functions as you expect it should....

If you can manually open lid completely, and it clears the roof, it sounds like your hydraulic cylinders that power the lid are getting weak and not fully opening the lid. Given your vehicle is 10 years old, the seals on the hydraulic cylinders could be wearing out. If this is the case, they need to be replaced or remanufactured. See http://www.tophydraulicsinc.com/index.html I've just sent two of mine to Klaus for repair under recommendation from another Forum contributor. Always replace in pairs....

Here's another resource for diagnostics.


Hope this helps.....
