Just wondering if you guys have ever had faulty new brake controller or one that has quit working? I bought mine new on e-bay-looked new in box...I have left turn, right turn, but no power to trailer eletric brakes...on my 99 suburban k2500...

I rechecked wiring...the blue wire--goes to controller...and it is sitting at 5pm postion (when you look into to the 7 prong connector from the front)

it is a Curt Discovery unit.........
Thanks.

 

i know on newer gm trucks you have to unbundle a factory trailer brake wiring harness and connect it to a stud in the underhood fuse block then remove a dummy fuse cover and install a fuse.

 

it's rare but some time's they are bad from the get go ,just check the trouble shooting instructions for the control first .
here are some good tip's from e-trailer on install on your truck to go over .
