I checked the motor for the rear glass and it is good; and when I turn the key to roll it up the modual makes the clicking sound so does anyone have any Idea what the problem is; it worked A few months ago and now it don't; I am assuming it's the modual. Anyone know or have any idea what the problem is.
 
How about a little more info?

What year is the RUnner ? it makes a differance.

I've had issues with both first and second gen Runner rear glass, some was wiring, some was relays, some were connections in factory plugs.

More info, and maybe what you have tried ?
 
It is and 85; before I bought it it worked; that was about one or 2 months ago; it has not really been run since but we put straight power to the motor and it worked; then I took the relay (modual) out; I don't know what else it could be cause like I said it has not been used at all.
 
That the relay is clicking tells me you are getting power,

Odds are, the wires in the harness are broken, drivers rear, under truck, where harness comes from body to tailgate, check the harness there, looking closely at the blue and blue w/white wires. pull on them, they'll more than likely be broken internally. that is the most common problem area.

If you have had the hard top bolts out, driver side, next to rear down tube of roll bar, be sure that bolt is in place and snug, ( there is a switch under that bolt hole that the bolt pushes on when installed ) many guys spin the bolts back into the holes for safe keeping, and break the switch off.

aLso make sure the rear wiper is plugged in at the top connection, and is in parked position.
 
Are you talking about the wiring harness that went into the relay? I am planning on today pulling the top off so I can work in it better; but I have the side panel off were the relay was at; I will check the bolt hole at the roll bar when I get it off. Plus the relay only clicked when I used the key to try and roll it up the switch up front does not seem to make the relay click; but the switch up front has been relocated cause the arb switches were put where the window switch was originally. Thanks for the info I will see if I can find any broken wires today.
 
Are your rear fenders rusted out? If so...that leaves a big whole in the bottom of the truck for water/dirt/mud/whatever to get thrown up behind your interior panels. I've had problems on several occasions with rusty old 4Runners and the rear window. Make sure all those connections are clean, take apart the module box relay thing, spray it out with electronic cleaner and let it dry. Then wrap it in a plastic bag, tape it up, and let it lay inside the rear access panel inside of the interior panels as to prevent it from happening again.

This may not be your problem...but if anyone has a rusty rear quater paneled Runner it will be a problem one day.
 
you have to have certain bolts in for it to work, it grounds with bolts in the top to complete circuit, some times those switches go bad or if the bolts are out it won't work.
 
I took the top off today so it would be easier to work on; anyway now I can't get the relay to click; all the wiring for the window is still what looks like wrapped in the original tape. I 'm not to good with wiring anyway but I have no idea were to start.
 
I have a whole good tailgate:driver:
 
Chase, there is actually a switch under that bolt, has nothing to do with a ground

The switch and button are plastic, with metal contacts internally, seen several broken apart by reinserting the bolt and over insertion.

Toyota rarely uses a body ground in a high amp draw circut, not reliable enough

That switch that you are talking about does it come apart or anything; it did not look broken from the bolt; I did not mess with it cause the compressor is mounted right under it. I do think with the top off that nothing works as far as the window goes cause I unplugged something back at the window when I pulled the top off. But I really don't know for sure; I am just trying to trouble shoot with no results so far.
 
witht he top of, you unplugged the rear wiper connection, I don't remember if that kills the circut or not, I believe it does.

The switch in the side panel also kills the circut when the bolt is removed, as not all Runners have rear wipers.

yes, the switch will come apart, especially if the bolt is run down to far.

as for the rear window, if the tail gate is open, or not latched all the way, it also will not operate.

there is a switch in the passenger side latch, if it doesn't latch the glass won't move.

I have also had a latch release cable corrode and not allow the latch to work , thus keeping the glass from operating ( a real bitch to get to when the glass is up and won't come down ) the cable is like $28 at Toyota, and they'll usually have it in stock.

If you weren't 4hrs away, I'd give you a hand.
 
There is a kill switch for the window when the top is off. It is under the first bolt hole behind the rear tire on the driver side. If you replace the bolt, the window will function with the top off.

It looks like the top off switch breaks ground according to the wiring diagram. It has three connectors. Here is the wiring diagram.

There is also a door lock detection switch on the driver side.

Thanks for all the info from everyone; the diagram will help alot I hope; I want have time to mess with it again until the weekend; unless I get A rainy day this week. Does anyone know if that relay can be tested out of the 4runner to see if it's good.
 
Here's a number diagram for the terminals on the rear window relay.

Apply battery voltage between terminals 1 and 3 of the wire harness side. Check that the window motor turns. Then connect in reverse, check that the motor turns in reverse. This checks out the motor etc.
Here's the check list for every terminal on the relay.
