When I purchased my CL. I was a bit disappointed it didn't have every option ie:auto trunk close,distronic,park assist. None of which I would use anyway.

Now it's obvious they are things I won't have to fix either.

 

awiner,
Can you tell me where to get the Pump Actuator for my trunk?

 

Is this what your looking for?

Thanks awiner,

 

Thanks for all your information. It has been quite helpful. Could you tell me how to remove the locking rod. I believe it should pop off the ball joint but I am afraid I might damage something. Would rather know what I am doing. Thanks again, John

 

Glad you were able to fix the issue.. I just fixed mine as well, my son crack a vacumm hose on my rear seat kicking it and leak kept shutting pump off, quick fix all good now.

 

I have just replaced the vacuum pump that activates door closures, door locks and lumbar bags ect. The old one had over heated and failed.

After replacing the vacuum pump, all the above functions work normally. But when I try to open the trunk, the trunk does unlock, but lift pump does not come on. The indicator light on inside trunk button does not come on.

Does anyone no what the problem might be?

 

Check your hydraulic pump under the battery. I bet it needs fluid.

 

Digging up an old thread. What kind of fluid does the trunk closer take?
ATF? Pentosin?

 

Either will work
Pentosin is higher quality synthetic , if you already have some use it
Otherwise no need to Spend on pentosin if you already have atf handy

 

So, got the pump off, but don't see any way to add fluid other than removing the reservoir, fill it up and put it back on.

????

 

Well, there may be another way but that worked for me.

 

i didnt even know that there is a hydraulic pump under the battery in the trunk. Wow.

 

Only if you have the power opening and closing trunk lid
Not all cl500 have it, some just have a trunk opener

 

I have a friend with a CL500 with the power trunk. His is acting up just like Sherri's was.

I have invited them over to the house (they haven't seen our new place yet) and offered to fix the trunk issue. If they take us up on it, I will take pics this time. Very easy fix. Hardest part was getting that mongo sized battery out of there. Awkward angle.
