Sorry if I'm beating a dead horse here, but I've searched for a solution and all the remedies don't seem to work. I drove my 2007 to work this morning and when I put the top up it stopped midway. When I turned around I discovered that the point of the tonneau had hit the back edge of the top. I released that and managed to get the top up and secured. Now the top won't do anything. I reindexed the windows, disconnected the battery for an hour, did the windows again, checked every fuse, tried pushing the top. Nothing. No motor sounds, no clicking, nothing.

I am getting frustrated as I believe it's something minor and electrical which usually means time-consuming and expensive. I have seen an excellent post on how to fix the tonneau/top interference issue. But that's not helping the current dilemma.

Any suggestions would be appreciated. Except holding CTRL-ALT-DELETE. That didn't work either.

I'm sorry that I can't help.

On the other hand you have helped me decide against a power top for a C6 convertible.

Did you check to see if the trunk divider may have somehow dislodged? I have never removed the divider so I do not know if you get a DIC warning message.

Also, how did the tonneau hit the top? Did the tonneau not open completely? Mine will hit the window if I do not hold the window inward as it passes the tonneau going up or down, but the tonneau opens completely.

So happy to be of service...

The tonneau hit the top just below the window. It's never done that before. But I read that if you shorten the straps by 1/2-3/4" that the tonneau will clear the top.

I tried the trunk divider as well. The right side switch seems to be functioning as intended.

you didn't say if it was operating again or not?

you have your owners manual? page 144 and on discusses power top operation and possible causes of malfunctioning.............

pdf of '07 owners manual here.............................

videos on YouTube for strap adjustment, and numerous old posts here.............. use Search function for glass hitting tonneau to find them..........

The top is still inoperable. Pressing the switch does NOTHING, no noises, no clicks, etc. The tonneau hitting the top is not the issue here, the fact that the top switch does nothing seems to be the immediate problem. But thank you for the pdf. I left my manual at work tonight.

I find it strange that there is NO fuse or relay dedicated to the top function. Am I missing something?

this fuse box is located under the carpet in the passenger footwell

Did you manually close your top?

Which one is labeled Convertible Top? There are 2 labeled with Tonneau. I read that if the tonneau doesn't release the top switch won't work. Tonneau is not releasing. I pulled and inspected ALL of these fuses. No luck.

Yes, following the hang up with the tonneau/top when everything stopped. This led me to believe that a fuse had blown or the BCM needed to be "reset" by disconnecting the battery.

Disconnecting the battery fixed my cruise control malfunction.

Please post when you find the cause of the problem.

Since it is a hydraulic system, I would insure that the release screw is tightened down so that it will hold pressure. Without pressure I do not believe the up/down button will do anything. Can you lift the tonneau manually?

ccrvtt

The top stopped when being raised because the tonneau contacted the back edge of the top. After I separated the two I manually closed the top and tonneau because the power switch did nothing. I tried disconnecting the battery, re-indexing the windows, the trunk switch, checked every fuse I could find, rotated several relays, made sure the deck lid was locked, tried releasing the hydraulic screw, etc. I have not found a fuse directly related to the top motor. I tried manually releasing the tonneau with the pull located behind the passenger seat.

I think I may be out of sequence in some of the stuff I'm trying because it makes no sense that the top motor, which I assume powers the hydraulic unit, would not be overload protected.

Thank you for your concern. My frustration level is very high & my wife is becoming convinced that laying on of hands and faith healing is the next step. Any suggestions will be welcomed.

If you were able to put the top the rest of the way up manually after it stopped, then that's an indication the valve on the pump wasn't tightened down and/or is low on hydraulic fluid or has a leak.

Are you getting any DIC messages?

The only time I've had the top switch not work with no DIC message, was when the windows weren't indexed properly. Maybe try that process again.

And...........check the switch in the dash too. Not likely, but you seem to have addressed everything else already.

Please let us know what you find, and for you buyers' considering a vert, I've had zero issues with my '06.

Hope I didn't jinx myself.

Good luck with this PITA.

There are two labeled 'tonneau relse', tonneau release and one labeled 'TPA', tonneau pull-down actuator.

And this one too-

So I went back into the fuse box and rechecked all the tonneau and the ALDL/top switch. The fuses are good and the continuity tester indicates current. I removed the dash switch and disassembled it and everything looks good. Tested the plug for continuity and it's good, too.

I manually lowered the top and released the hydraulic pump. Then I raised the top and retightened the pump screw. I have re-indexed the windows several dozen times.

I have printed a TSB 09-08-67-013B and I am trying to make some sense of it. This TSB addresses shortening the limiter straps for the 5th bow to keep the rear window from contacting the tonneau.

I even read the owner's manual again and waited more than the required 5 minutes from the last time the switch is used to go to manual operation.

I would spend the $28 for online assistance if I thought that would actually fix my problem. Anyone have any input on that?

This is from a 2013 post (TERRADRILLER). Sounds like the partition switch.

I had this happen on my 06 vert after having the trunk full of luggage on a long trip. The partition snap was snapped tight but the switch on the right side was not depressed far enough to close the circuit. I put a small piece of tape on the back of the switch so the switch would be depressed far enough to make contact..

All is well with the top, no further issues so far.

My top stopped half way down once. I got a warning that the partition was not in place on the DIC. Popped the trunk and it was still in place so I tried again and got the same message. After unfastening and refastening it worked. I did not see where you were getting that message but perhaps something to do with the switch?
