I have changed the fuse a couple of times but now it blows instantly. The only thing I know that is odd is the backlights on the heaer control *****. I need to tap the dial in order for the lights to come on. Other than that the bulbs are good and new looking. Fuse block looks good too.
Any way to find the short???
Thanks!

 

your grounded out somewhere

 

Unplug things one at a time until it doesn't blow the fuse any longer.
