GM Tech (Cam) :

Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.

GM Tech (Cam) :

Specifically which fuse in what location?

Customer:

30 amp under hood

Customer:

ignition fuse according to the fuse chart

Customer:

did this once before about 8 months ago

GM Tech (Cam) :

Does it pop before or after you turnt he key?

Customer:

after

Customer:

we replaced the fuse and had no problem until today

GM Tech (Cam) :

Ok, is a remote starter installed?

Customer:

no

GM Tech (Cam) :

Then you have a short around the igniton switch or steering column.

GM Tech (Cam) :

Have you looked at the wiring there?

Customer:

not yet

Customer:

was told that ignition switch is common problem is this true?

GM Tech (Cam) :

It is, but to short out and pop the fuse is not as much of one.

Customer:

so then most likely a short in the actual wiring

GM Tech (Cam) :

Ithink it is yes.

Customer:

in the steering column or can it be somewhere else on the car? like at the starter?

GM Tech (Cam) :

Does it only pop in start or with the key on?

Customer:

all I have to do is turn the key to the on position and it will pop

GM Tech (Cam) :

Ok then not the starter.

Customer:

so then a short in the wiring harness somewhere?

GM Tech (Cam) :

AFter the ignition switch but before the fuse blocks. Pull these fuses and see if it still pops.

GM Tech (Cam) :

Full Size Image

Customer:

ok sounds like a little more then I can handle not sure what fuses to pull

Customer:

would the short be in the actual harness or is there a ground point that should be looked at

GM Tech (Cam) :

In the harness where it is chaffing likely.

Customer:

ok thank you
