My worst nightmare seems to have come true. My hard top wont retract and my trunk will not open/close unless done manually. I found about 4" of water in the left side trunk electrical compartment. How many components did this destroy?? And how costly will be to replace.
I'm so sad.
This is probably the easiest common XLR problem to avoid, and one of the more expensive repairs. Yours is not the first post of this issue in the XLR section, and it unfortunately won't be the last.
Your problem was most likely caused by a clogged drain line at the bottom of the compartment that houses the Folding Top Control (FTC) module and Suspension Control module. At least one (or both) are fried.
If the hydraulic pump is toast, you're looking at around $2500, (parts and labor) the Suspension module is $700, and the FTC module is a little over $500. Labor will be a few hundred to install the modules and calibrate the top. So the price could be between $1000 and $4000. Suspension modules were in short supply last year, and if more haven't been added to the supply system, you could be waiting months for one. --That just goes to show you how many have needed replacement.
Every XLR owner should inspect the drain line at least once a year. You should be able to see light through it from the open trunk with the left side tub cover removed.
For any XLR owners that don't know the status of their drains: This is a five minute check and can save big bucks! If the end of the plastic drain tube is pinched shut, cut the tip off.
There's also an approved procedure the dealer can perform to better seal the trunk area with some little sticky gasket strips that are applied near the front of the rear deck lid.
