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) :

Isthere power to the plug they are plugging into?

Customer:

Not sure how to check that

GM Tech (Cam) :

Does the lighter work?

Customer:

I'll have to check that, don't use it. Can you wait?

GM Tech (Cam) :

sure.

Customer:

right back

Customer:

Lighter does not work

GM Tech (Cam) :

Check the CIG fuse/

Customer:

is that under the dash?

GM Tech (Cam) :

dash

Customer:

let me check, right back

GM Tech (Cam) :

ok

Customer:

The only fuses I can find are in the fuse panel next to the battery, and there is no fuse there for the cig lighter??

GM Tech (Cam) :

Open the drivers door and there is a small panel in the end of the dash.

Customer:

ok

Customer:

blown fuse, replacing it will just give me power to get the code readout, correct

GM Tech (Cam) :

yes, that fuse powers the data plug

Customer:

great that gets me a little farther in clearing the real problem

GM Tech (Cam) :

Do you have a code number now?

Customer:

no I have to check the reader out at the parts store, don't own one

GM Tech (Cam) :

ok

Customer:

I'm hoping to find the code cause online somewhere

GM Tech (Cam) :

or P0440 or somthing like that.

GM Tech (Cam) :

thre are far too many to guess at.

Customer:

guess I didn't gather the correct info from the devise I'll have to go back and try again

GM Tech (Cam) :

Sorry to have to ask but that is the only way I can get you the proper answer.

Customer:

give me a pre 70's car and I'd be fine

GM Tech (Cam) :

LOL, true enough, get me on older than about 95 and I am lost.

Customer:

I think you would do just fine, all you have to do is remember were the bolt came from

GM Tech (Cam) :

I know the mechainal stuff but understand the electronics and sensors better.

Customer:

I'll be back

GM Tech (Cam) :

ok

Customer:

code was P0480 cooling fan circuit, fuse was blown replaced the fuse and it's OK now. I suspect the fan motor may be going bad.

GM Tech (Cam) :

That is most often the case.

GM Tech (Cam) :

I have only 5 mins before my family drags me out the door to the pool

Customer:

I'll have to see if I lose another fuse.

Customer:

go get wet thanks for your help
