    2006 Escalade back tailgate won't lock

    The rear door on my escalade will not lock. The rest of the doors will lock and if you open the back door(tailgate), the security alarm goes off. The rear door was making a funny noise right before this happened.
    thanks

    Hi,

    I also have a 2006 ESV with the exact same problem. All other doors will lock and security alarm will sound if back lid or door opens.

    Were you able to get this problem resolved, if so, what was the fix?

    Regards,
    Michael

    I too have the same problem with my 2006 Escalade EXT. I verified the solenoid was good, and replaced the actuator with a OEM replacement part for <$115, not $500 that some other responses stateed. The big challenge is getting the rear liftgate open!!! You have to crawl over the back seat and with a then blade (paint scrapper or thin flat blade screwdriver, you can unlock the glass door and liftgate. You have to carefuly pry the rear plastic panel off the cargo door being careful not to break the retaining pins. Look at this link for a step by step outline to complete the liftgate actuator replacement. http://www.justanswer.com/cadillac/6...e-esv-bad.html

    best of luck!

    I have seen this problem on a 2006 Escalade. The rear liftgate won't lock but otherwise works. This thread may help someone.
