i am having trouble wityh the trailer lights on my 99 psd i have hooked up to 2 diffrent trailers sometimes they dont work at all and other times the blinkers dont work nor the brake lights but the running lights work...and suggestions?

 

I am having the same problem. The lights on the truck work fine. I tested the plug and am not getting anything there. Have you corrected your problem yet?

 

Are those trailer plugs Matched to the *Standard Positions* per the connector?

I have my trailer connector set special for me & MY truck.
I also have pigtails that converts it to standard wiring.

If someone tries to steal it ,they will noticed by other drivers.

The other thing is I have the continuous power to trailer actually hooked up to the trailer brakes.

 

Mil1ion,
Mine look exactly like the photo, (factory install). The trailer lights have worked for years. I hooked up yesterday and had nothing but taillights!! I have tested the harness on the truck and it seems o.k. (continuity check). I hooked the trailer to another vehicle and it works perfectly.
Thanks,
Ken

 

Possible corrosion at the Truck connection terminals ?

 

I disconnected the harness and checked the terminals. They were in great shape.
In searching previous posts, I notice that this is not that uncommon an occurrence. The posts that I have reviewed however do not give explanations as to how the problem was solved. I cannot directly e-mail anyone because I have not been a member long enough and do not have enough posts. Frustrating!!
Thanks,
Ken

 

WhipsnHorses directed me to a third fuse box that was not mentioned in my owners manual. 20 amp mini fuse blown. Trailer lights operational once again. Thanks so much for the help.

Yes frustrating it is when people don't follow up thread with the end result being positive or negative.

Mostly it is because people don't go ( too lazy) find that original thread to update.

Glad you got it fixed

 

Thanks for the note Dennis. I guess the third fuse box wasn't detailed in the owners manual because the towing package was an option(???). Anyway,... lesson learned...
Merry Christmas,
Ken
