Hi Guys,
Need your help please. Just took delivery of our long-awaited 2020 C8 Convertible.
The 2 keyfobs will not retract the roof nor lift the toneau cover (engine cover).
I am either doing something wrong, OR they changed the procedure (Like they did with the frunk opening sequence) or something is defective.
Can you help?
The keyfobs will unlock and lock the doors, so they are not dead.
The inside door switch will lower and raise the roof.
As the tonneau cover can ONLY be opened with a keyfob (no button inside car), I need to solve this problem.
A. To open roof (put top into trunk):
Trunk closed.
Tried with car OFF, ACC or ON (running) in "Park." Distance near or inside car.
Press and release "unlock" button on remote.
Quickly press and HOLD! "convertible" button for few seconds, waiting for something to happen.
RESULT: NOTHING HAPPENS.
Did all the troubleshooting stuff on page 44 of the manual. No help.
B. To open Tonneau cover (gain access to engine):
Trunk closed. Roof locked in up position.
Tried with car OFF, ACC or ON (running) in "Park". Distance near or inside car.
Press and release "lock" button on remote
Press and HOLD! "convertible" button for few seconds, waiting for something to happen..
RESULT: NOTHING HAPPENS.
Also tried the variant seen in the GM's 2020 Corvette Accelerated Preparation video, where they say just to: Press (NOT HOLD) "convertible" button as the 2nd of 2 steps.
Repeat all procedures with keyfob #2 - same null results.
Stuff I already know:
1. Roof can ONLY be closed via the door switch, NOT remote.
2. But tonneau can ONLY be closed via the remote.
According to page 45-46 of the manual, to close the tonneau cover:
Vehicle OFF.
Press "lock" and quickly press and HOLD! "convertible" button to start closing tonneau cover.
The remote key MUST be used (ie. they imply no way to do this via any button inside car).
Did all the troubleshooting on page 46. No help.
SOLUTION to problem:
Anyone have a convertible that can tell me what exact steps they use to work the remote control for the roof and tonneau, and is the car in on/off/acc? Thanks for your help.
