RobbyP33 10 Posted June 20, 2017 On my 1990 corrado the passenger door will not lock or unlock with central locking. The pump is on and off within one second and does not seem to be timing out due to a vacuum leak. Would would be other causes of this issue? Thanks.

voo51 0 Posted June 21, 2017 Take the door card off and check the electric cable that runs to to the solenoid for breaks. You should take some of the black tape off that's wrapped around it. It's common for the cable to deteriorate over time dispute it being inside tape. Quote Share this post Link to post Share on other sites
