Couple of observations when rebuilding roof cylinders
Over the past week I have rebuilt or helped rebuild four of the front locking roof cylinders. Of the four cars we did, all still had their original seals and only one of them, the 1999, had a seal that was at all cracked and none were leaking. The '99 may have been getting close to springing a leak, but the '01, '02 and '03 that we did all looked good. That made me think that the other four cylinders could wait awhile, maybe a long while. Since none of them cause collateral damage like the front one does to the headliner, I see no real need to rush into the job.
The other thing to note is that we could not figure out any easy way to remove the wire clip holding the actuator together without drilling a hole in the actuator. It just saves a lot of time and effort to just grab your drill and go at it.
Give yourself a couple of hours to do the job. It's definitely a DIY operation.
Thanks to the instructions supplied with the kit and the good tips given here by others, the jobs went reasonably smoothly.
