IG1 NO. 2 blows instantly

@TnShooter @Dm93 when i heat the windshield defroster I can hear a slight thump behind the dash? Is that normal?

 

Possibly. The mode door will close/open. If the blower isn't working, you'll hear some noise.

I the IGN fuse back in? (Not blown)
Is the HTR relay in?

The heater fuse is in the fuse box as well as the CDS fuse (engine bay)

 

@TnShooter thw IGN fuse is back in and hasnt blown, and the HTR relay passed both the multimeter test and the 9V test and is back, how do i test the CDS fuse?

 

I guess we could check the relay powers and grounds for the blower motor.
But check the things in my post above.

 

Let's check the blower motor relay pins in the fuse box.
We need to know what's missing.

 

Is it this one? @TnShooter

 

That's one of them, the other is 50A HTR

 

Pull the HTR relay.
Turn the ignition switch ON, and the Blower (air) ON.
Check pins 5 and 1 for 12v (battery voltage)
And pin 2 for Ground

 

Here is the diagram for the fuses.
Fuses 12 and 16
(I bet they are good)

 

@TnShooter so some how we are back to square one, i realized i never re put in the 30A CDS FAN relay so i put that one in and the fans worked for about 1 minutes then the 1GI blew so there is sowmthing else besides the radar that it shorting.

 

@TnShooter i took out the the 50A HTR and the 30A CDS and the 10A still blew.

 

So the fuse blows when the radar is plugged in AND when the CDS relay is plugged in?

 

@TnShooter the fuse is blowing with the radar disconnected CDS disconnected and the HTR disconnected made an appointment with the stealership on Monday, will keep posted.

 

Weird. I thought we were getting some where, but now we're back blowing at a different time.
It's back to looking at a wiring issue again. Wish I lived closer to you, I'd offer to come over help.
One guy watch a test light while the other guy disconnects and wiggles wires.

 

Did you ever inspect the wiring under the truck?

If you do take it to a shop make sure to tell them about hitting the pothole, as a tech info like that can save alot of diag time.
