Folks,
Have searched threads but couldn't see anything on this... much appreciate any suggestions, especially based on hands on experience..:
Rear N/S door intermittently fails to lock. I bought pack of four 2nd hand solenoids, and changed door unit, but exactly same scenario. Changed unit again for another spare 2nd hand unit, and lubricated all in-door mechanisms, but still exactly same problem.
All other doors work fine. Wiring at solenoid end is fine. Mechanism feels fairly free, with no apparent stiffness or anything seeming to catch or get stuck.
Interestingly, a month after changing to 2nd unit sympton improved (from approx 1 in 3 failure rate to approx 1 in 6). But when changing to 3rd unit problem now occurs every 1st attempt to lock door... If I then unlock and relock it normally now locks on 2nd attempt...!
Seems strange.. hardly likely to be a broken/fatigued wire.. and unlickly to be 3 different solenoids (incl the original unit).
Is their anything in the door mechanism that can stick/jam to cause this effetc or other know causes?
