It's too late to call HSW, so I figure a post will help quicker right now..ha


I've had the HSW Interface for awhile and it's always worked perfect. One random day, it started giving me problems.

The "ON" light always flashes. None of my wiring has changed, so I'm not sure what could have happened.

I've double checked my wiring with diagrams and I'm not sure what else to do.



I have the Nitrous Outlet single stage window switch. Like I said before, I've never had any problems, it was just random.

 

Ummm...So I just made this post and it wasn't working... I go outside, don't touch anything burn turn on the ignition, and it stopped flashing.

Obviously, my car is possessed..

 

I would still give HSW a call today or send them a PM.

Did you check all the actual wires? You may have a chaffed wire that's causing an intermittant problem.
