Weekend mod electrical woes

Ok, so I just bought an 08 limited and dove right in and did a couple electrical mods on my weekend and I'm having a couple issues... After I finished these mods my right turn signals do not activate, nor does my power defrost button. After reading another post earlier in this thread, I suspect that my rear wiper will not be working either.

The first mod that I did was the fog light mod. In following the write-up I connected prong #2 on the fog light relay to the 25amp seat heater fuse via add-a-circuit, as I had an IG relay and was unable to use that connection. The second part of the write-up I followed exactly. Fog lights worked beautifully, exactly as intended. I did not think to test anything after this to see if I had lost function of any other electronics.

Next, I did the 12v constant power mod. Super simple mod, followed the directions to remove the DC SKT relay and place a jumper wire from pins 3 to 5. 12v front and rear units now worked without the key being in the ignition. Still didn't test anything to see if I had lost function of other electronic connections.

Last, I tried the 115V constant power mod. Similarly to the fog lights mod, I connected pin #2 on the ACC INV 115v Relay with the AC 115V INV 15amp fuse via add-a-circuit. I then pulled out the jumper wire I had just inserted in place of the DC SKT relay and created a new one with an extra lead coming off to be connected with the yellow wire with a red stripe coming off the 115v AC switch in the dash (per the write-up). I connected the jumper, cut the yellow/red wire on the switch, taped off the portion leading up to the dash and connected the lead from the jumper to the yellow/red wire connected to the switch using another blue 3m Scotchlok Electrical IDC connector.

Here's where problems started happening:
I depressed the 115v AC switch and the light came on the switch, but no power to the actual plug. 12v sockets both still had power, I didn't test the fog lights but in the end they still worked the same.

I tried two things next, but I can't remember which yielded what results. I tried reconnecting the yellow/red wire with it's original other half, and then touching the lead from the DC SKT jumper to that connection. It didn't work the way I wanted, so I pulled the ACC INV 115v relay and add-a-fuse going to the AC 115V INV 15amp fuse. The result was power to the 115v inverter, but my center display (clock, outside temp, heater/fan read-out) and my temperature controls were also energized without the key. I replaced the ACC INV 115v relay with the untouched DC SKT relay so it would be back to stock, and I reconnected the yellow/red wire with itself (basically un-doing the mod).

12v sockets still had constant power, fog lights still worked the way the mod intended. That's when I noticed my right side turn signals (front and rear) did not actuate when engaged. My emergency lights work fine, brake lights work fine. Front running lights work fine. Just the turn signal. And defrost button, and probably rear wiper (I'll update when I get home tonight).

I'm not an electrical genius so any help would be greatly appreciated.
Thanks!


:edit:

Just undid all 3 mods, completely back to stock, still having turn signal, defrost, and rear wiper issues. None of them work. ****. :moping:

Dumb question, but did you check to see if you happen to have burnt out any of the factory fuses?
 
I'll have to give the turn signal some thought, but try rolling to rear window all the way down then all the way back up. I believe the defrost/rear wiper are disabled until you do that because the vehicle has no way of knowing if the window is rolled up all the way. It's to prevent you from spraying washer fluid into the back of your 4R. Give it a shot.
 
So does the rear wiper work or not?

Lets see a pic of the engine room fuse box, focusing on the connections made to the fog and the acc inv relays.

I looked over the wiring diagrams and dont see how these issues are related. I have had all three mods running on my 07 since 07 with absolutely no issues.

Rob I'll give that a shot, never thought about that. I know my auto up/down on the driver's side didn't work initially either until I put the window all the way up and down. Sweet Jesus I hope it's as simple as that lol.

J - I don't have any pics and I'm at work until 7 tonight, honestly my connections look EXACTLY like the write-up pictures with the exception of the fog light mod (I used the seat heater fuse instead of the IG relay).

Also, everything is undone right now and reverted back to stock.

:edit: sorry, the rear wiper does not work
 
Just had my girlfriend try the window up/down reset and it fixed the defrost button and wiper. No dice still on the turn signal -___-

That's a lot better, is it still just the right that does not work or both? That being the case I would examine closely all the wiring in the stalk location to 100% eliminate the possibility of any wire being accidentally cut or simply being pulled out of the plug itself when you Scotch locked the wires together originally. Good luck!

That's correct, it's only the right turn signal. I've looked over those wires several times now but can't find anything damaged or out of place.
I will look again when I get home tonight.

I know yours is newer and maybe [MENTION=15785]J.A.[/MENTION] can chime in to confirm, but based on the 03-05 wiring diagram the G-Y (green-yellow) at the stalk location is for the right signal.

Same color on the refreshed newer years.
 
Hokay, so, turned the key to the on position and started fiddling with wires in the bundle under the steering wheel.

Turn signal starts coming on intermittently. Start fiddling with the main connection, nothing, start fiddling with just the wire and some more intermittent connection.

Then I try to separate the wire from the rest of the loom a little more and *snap* it breaks. Touch the two tips together, solid activation of the signal. Problem found! Thank you all for your help and suggestions!

Awesome!!! Glad we could help.
