Slide motor relay clicks but motor won't come on

check fuses- relays -motor -gearing--track for damage or debris

Have a look at the spade connector that connects to the starter motor.
Pull it off the starter motor and look in the end of it.
The gap in the connector might have opened up.
If it has take a pair of pliers and squeeze it closed a little bit.
Slide it back on and see if it works now!!

The switch and the wiring to it is too lite to handle the motor current. You will fry the wiring without the relay. You can get an external automotive relay ans operate the coil in it with the existing switch. Just make sure the contacts in the relay are heavy enough to pass the motor current or you'll destroy the relay.

Park neutral safety switch maybe be the reason for the no crank ! Try putting the vehicle in park ,then try to crank the engine . Testing the electrical circuit is the best way to trouble shoot this problem , along with do a voltage drop test on the starter circuit ! This will test the battery cables an connections .

How to voltage drop test starter motor circuit
Does it have a manual or automatic transmission ? Manual ? clutch switch . Looking at a wiring diagram I also see a starter cut relay !

Then click the search button , then click the blue link ! Check the starter cut relay also . Videos on youtube showing how to test a relay controlled circuit !

This is a bad motor ground cable. I call it the 1 click no start.
test by jumper cable on motor and other end to battery ground post.

the clicking sound is the starter relay check battery starter motor and this clicking relay hope this helps ivan

Starter motor solenoid replaced or replace bushes.

I would need to hear this.

Unplug all wires and cables and there should be about two - three bolts holding the starter motor in place so undo them and it will slide out.

You wouldn't have a blown fuse if you can hear the relay

Have you not checked the fuses before asking a question?

Relays don't fail a lot & you hear what may be a relay,
although maybe not for the window circuit.

How would someone one the internet know what your
problem was,without at least being next to your truck?

I would say you have a bad switch,as that is what is used
the most. If not then the motor or a jammed window regulator.
