4 BUY 4

I have a 99 4 Runner Limited and I’m having problems with my trailer lights and I’m looking for some help. First, the problem isn’t in the trailer. I’ve hooked the trailer up to 3 different trucks including a Lexus and the lights work just fine. I’ve towed probably 10 different trailers with this truck and didn’t have a problem. It’s a snowmobile trailer with a bunch of extra lights on the outside and a few additional on the inside so it’s drawing quite a bit of current but the other trucks don’t seem to have a problem lighting it up.

Let me give you some history. The running lights won’t work but the brake and directional don’t have any problems. I cut the wiring on the trailer so I’m only lighting half of the lights thinking it might be drawing too much current. Now with only half of the total lights hooked up they work. As I try to add more lights to the system the running lights on the trailer only cut off. Once the lights cut off to get them back on I turn the lights on the truck off and on again. There must be some sort of breaker that blows and turning the truck lights off and on again must reset it. Sometimes I have to do it two, three or sometimes four times to get the trailer lights back on. WHERE IS THAT BREAKER AND COULD IT BE CAUSING MY PROBLEM? After a while it wouldn’t even light up half the lights so I reduced the number down to a quarter of the total trailer lights and they came on a gain. It’s almost like I’m loosing more power to the trailer every time it cuts off.

I took the truck to the dealer. They charged me $50 bucks and told me everything was fine but they didn’t test it under load. Everyone else’s truck lights up all the lights without any problem. The problem must be in the truck, but where it is, or how to fix it, I have no idea.
