HELP!!! Severed wires

HELP!!! Severed wires

Postby ralphstudders [OP] » May 2nd 2018, 4:53am

Howdy all,
I am in the process of camperizing an '02 astro.
after installing and removing and installing a plywood subfloor several times I began to experience failure with the mechanisms of the rear door.

1. key fob would no longer lock/ unlock rear swing hatch (dutch doors).
2. rear swing hatch would not lock at all
3. swing hatch lock actuator (i think) stopped working (rear swing hatch will not open without manually moving release mechanism)
4.power locks stopped working in general.

after problem 3 occurred I started looking at all of my wiring and found that I had severed a couple of wires that lead to a white (fuse?) box that is attached the the wall behind the rear passenger side wheel well.

I used butt joints to rejoin the wires in hope to fix the issue but it did not work. I have looked in the fuse boxes underneath the hood and beneath the steering wheel and there seem to be no fuses that are blown. I pried open the white box to which the wires connect but all seems to be alright in there as well.

This is the only damage to the wiring (that I can find).

Does any one have any insight as how to proceed.

Thanks all.

R.S.

That would be the rear door lock relay. What about that lonely green wire that doesn't appear to go anywhere?

It is in there Wimp. It's just hiding behind the other wires.

Based on my schematic, it should be the 25A PWR ACCY CIRCUIT BREAKER in the instrument panel box... I've never seen it... but it is there...

Otherwise, it is a mystery to me. If all those wires are in the right places it should work. Even if you broke that relay, I think the other power door locks would work.

Thanks for responding to the SOS

I'll recheck my fuses in the am. Is there a box I am missing somewhere in the van?

Is there a chance I need to order another relay?
Appreciate the knowledge gentlemen

Not a problem man. Only fuse boxes I know of are under the dash and under the hood.

I doubt you busted the relay.. because even if you did I think the other door locks would work.

Check this thread too...

PS: if you right click on Leeann's schematics in that thread and select "open in new tab" you'll be able to see those VERY nice schematics.

If you actually shorted some of those wires to each other or grounded them it is possible that the module that drives that relay has been damaged. You mention power locks not working. Is this using the switches on the doors if you have them? or is it just a keyfob issue. There is a module way up under the dash for people that have remote door locks that is the receiver for the keyfobs. This is what drives that relay and the power locks.

Sure as snot, blown fuse.
The cig lighter fuse (13 under the dash) had popped.
After replacing it the rear hatch once again opens, locks both from the keyfob and the door switch, and power lock switches on both front doors are firing.
Thanks for the advice gentle men.
