My cruise control worked when I got my car (in 2011) then stopped working a year or so later. The switches all seem to work (based on dash indicator light goes on/off when commanded, and above 35mph), and the brake disengages it. It failed over time, where the cruise would only hold for a little while, continuing to having no response at all. Never tried to fix it until now. Looking at the servo, it looks like it's cracked, but with it bolted in place, it's hard to get a better look at it. Has anyone seen these units crack like this (see 2 opening on bottom of round feature) before? Is this going into the vacuum chamber rendering it useless? There is a PN visible on it, is the PN I need to order 4W13-9C734-AA? There are plenty of "hits" on the 9C734 part of the PN, but many variations on the prefix. How do I remove the vacuum line from it? ![](https://uploads.tapatalk-cdn.com/20190203/dac5920b998123a7877e6ef4dd5b1f44.jpg)
