Symptoms of fault
Door lock jumping up and down quickly, door not locking or only periodically, door lock rattles.
The fault
A spring within the door lock actuator mechanism snaps causing the locking faults.
It is a common fault on these vehicles for a small spring within the door lock actuator to snap causing the symptoms noted. The original spring within the mechanism is very thinly wound and is constructed from a poor quality steel which will inevitably corrode and the spring will snap. Previously this necessitated the complete replacement of the door lock actuator unit at vast expense, the vehicle manufacturer has not altered the spring design / construction over the years so even installing a complete new actuator would only be a temporary solution.
The solution
Simply install our improved design replacement springs and restore your locks for good.
Made from high quality Stainless Steel (will not deteriorate over time like springs offered by some others) our improved design thicker wound springs will restore your lock and will not deteriorate over time like the OEM part does, save the cost of a replacement actuator that will just fail again.
