Electrical problem with tailgate window

Ok...now i have a problem at my own truck...

I can't move the tailgate window when the tailgate is closed. I already have bridged the limiter switch, without success.

I only can move it, when the tailgate is opened and I'll close the latches or bridge the switch. If I try to close the tailgate, the window stops to work close before the tailgate is closed.

Is there another switch? I only found one inside the tailgate on the driver's side.

Thanks!

Rene' I believe you probably have one or more broken wires where the harness bends entering the tailgate. This is not an unkommon issue on power tailgate windows.

Hi Gary!

This is a good point...I already have had repaired two wires in the past.
I should check it and replace the cable.

Hi, Rene. But that was Bill that answered your question, not me.

Hi BILL!!!!!

NOW I answer the right person...

I've found the problem exactly where you've said:

Two wires were broken directly after my repair shells...now I'm changing all three wires completely to a 3x2.5mm² H07RN-F cable.

No! That was me!

Actually, it was the old sage, Bill. Isn't he a wealth of knowledge?

Glad you found it.

Having owned a couple of Fomoco wagons (1970 1/2 Falcon and 1971 Colony Park) I am quite familiar with broken wires at the tailgate hinge, particularly since both were dual action tailgates.

Re: Electrical problem with tailgate window

So, I've fixed the problem:

Before:

One of the wires was corroded completely after the connector behind the taillight.

After:

I'll change the complete wiring harness in the future. I'll also change the H07 cable again to one made for robotic applications, cause these are very reliable and flexible.
But also by now the window already runs much faster.

Those Scotchlok connectors w/o the moisture seal are a very poor choice in situations like that. Glad you got it fixed, at least for the moment, with a very good solution later.
