antman Posted October 14, 2015 Report Share Posted October 14, 2015 1999 c70 convertible 130kThe top on out c70 hasn't worked since I purchased it I finally decided to look at it now that winter is coming .What I have found is the passenger side rear doesn't pull down all the way and also wont unlatch this I believe came out of adjustment from the previous owner messing with it so that needs to be adjusted properly .Now from me playing with it I have lost the spring for the rear micro switch and broken the 2 pins that hold it in the proper spot . Is there any place to purchase a new spring ? the switch I can repair.I got the back to back to function enough for testing . The front is the part that the previous owner complained about . It will unlatch and go back a little bit maybe 6 inches then stops and wont move either direction the . you can here the motor sounds stressed it starts strong then you can here it slowing down . is there a way of testing the motor to see if its worn out ?

Ihatespeedbumps Posted October 25, 2015 Report Share Posted October 25, 2015 As much as I hate to tell people this, you are going to need to take this to a pro to have diagnosed. There is a special scan tool needed used to pull codes and diagnose this properly. Link to comment Share on other sites More sharing options...
TIZIO AKA 1 HND MEC Posted October 27, 2015 Report Share Posted October 27, 2015 First of all, try to open/close manually the top with the keys that came with the car or fab some(easy), procedure is on the owner manual at the end almost. Dealer will lie to you and say "your car need 2 motors out of tree " $1400 +labor. Do your home work and you will see you can do it! Link to comment Share on other sites More sharing options...
Fran9690 Posted October 28, 2015 Report Share Posted October 28, 2015 As ihatespeedbumps said, this is more of a dealer thing to diagnose. There are several position sensors in the top that the car references to know what position it is and how to time the top as it travels with all the moving components. You need VST to be able to pull the codes and see if exactly could be at fault, could just be a calibration issue, could be something more in depth. No way of knowing without having it scanned unfortunately. Link to comment Share on other sites More sharing options...
antman Posted November 9, 2015 Author Report Share Posted November 9, 2015 Thanks for the info I'm going to try and get the back part of the roof recalibrated tomorrow and the micro switch back in found the spring once that's consistent ill move to the front to see what's binding or if the motor has just gotten worn out .
