Step Switch

Problem: Step fails to retract when ignition is switched on.

Likely Reason: Step initiation (limit) switch failure.

Probable Cause: Corrosion by water, salt, road debris etc.

Remedy: Replace limit switch.

Tools Required: Size 2 med Phillips screwdriver, small or long nose pliers.

Method:

With ignition turned off, face the step assembly.. On the left is the step motor housing. To the rear of the motor housing find a bracket holding a simple push type on/off switch. This is the switch which initiates and completes the automatic lifting of the step on the ignition.

On top of the switch are 2 female shrouded spade connectors. Using the pliers disconnect these 2. At this point it is possible to test whether the limit switch is definitely at fault. To do this, turn the ignition switch to the “on” position. Take the 2 disconnected wires. One is connected to the chassis (earthed) by means of a screw; disregard this one. The other disappears into black conduit. Take the end of this one, and keeping your hands etc clear of the step mechanism, earth this wire to the chassis (a short length of wire stripped at both ends may help). If, on making the earth connection the step moves upwards, then the switch is definitely at fault.

Turn the ignition off. Take the screwdriver and unscrew the screw which fastens the switch into the bracket. Pull out the faulty switch and discard. Fit the replacement switch into the empty socket, replace the screw and refit the connectors (any way round). Put the step out, turn on the ignition and hey presto! watch the step retract on the ignition for the first time in months.

It is a good idea, at this point, to cover the new switch and connectors in a liberal coating of grease or Vaseline in an attempt to keep the water out. It is worth mentioning that in the worst corrosion cases it will be necessary to replace the connectors and some may even fall apart in your hands. So inspect the job before you start and make sure that you have everything you need to complete the job before you start. Connections and crimping pliers are available from most motor spares shops.
