I have a popup tent trailer that was given to me last year by my in-laws, which is old but in good shape. I know the brake lights wiring on it works fine, because it works when hooked up to their vehicle. However, it doesn't seem to work when plugged into my Chevy S10 blazer's wiring. So, I am confident the problem lies in the wiring portion on my blazer.
So, how do I go about troubleshooting the wiring to find where the problem is? Or do I need a professional to look at this, and if so, any recommendations?
Thanks,
Kevin

I had a 1999 chevy s10 blazer until about 3 months ago. After wiring, a new engine, new transmittion, ball joints every year, the entire interior falling apart and another laundry list of problems needing to be fixed I sold it and bought a real vehicle!!! a DODGE truck! Might not be a solution to your problem, but i felt your pain for years!

lol I've actually had the opposite experience as you. As a matter a fact, I think I remember when we went to that floatilla at Jordanelle a couple years ago, you had your blazer in the shop that week and borrowed a car.
We've had this blazer for about 5 1/2 years, (my wife had it before we were married) and it has been good to us. It has needed some minor work like any vehicle its age (1994), but the engine and tranny are still going strong and it's in reasonably good shape.
That being said, I WILL be replacing it as soon as I pay off my car (in like 3 years, lol!).
Now, don't even get me started on Dodge!!!! I HATE dodge, ever since my dad has owned 2 dodge caravans (what a joke of a vehicle) and hearing other people's experiences with them.
Now, when you wanna talk REAL vehicles, Toyota Tacoma is a REAL truck! I still cry every night about having to sell mine when my son was born (no car seat in that sucker). Those trucks will go ANYWHERE! [cool][

Lot of times it will be a bad ground if you get nothing . Try hooking up a jumper cable from the chrome bumper on the truck to the metal trailer (Helps if it is not painted ) and see if you have any lights after that . I believe the white wire is the ground on the hook up plugs .

do you have a test light?
If so take and clip it to your bumper and have someone turn on the lights, press on the break and tur. on the signals. While they are doing this poke the tip of the test light into each of the plugs to see whick plug lights up the light with what function.
If you get no reaction from the test light then you have a problem with your blazers plug, but if all looks fine by the light then the problem lies in how the trailer plug is wired. it is relatively easy to rewire a trailor plug

Thanks for the advice guys. I already know that it is not the trailer wires, since it works when connected to my in-laws blazer.
What I really need is to figure out if it is a bad ground, a short in a wire somewhere, or if the plug on the blazer is bad.

Use the method described by fish4fish, but becareful when you are testing the plug that you only touch one prong at a time or it will arc, blow a fuse and cause you to have to change your shorts!

Having gone through the pains of older wiring in older vehicles, I would reccomend this. Buy a new wiring harness and ditch trying to fix the old oxidized and corroded junk you have there. I have gone through the strokes on a couple older vehicles and ended up replacing it all anyway.

Take OEJ advice, if you can afford it, just buy a new plug. And use that electrical grease to keep it from oxidizing and corroding. I believe any autoparts store sells it. Have fun with the new toy!
