I have the fuse right in front of me and I can see it is blown.
How long would the CEL stay on after the event. If for just a short period I might have missed it although I doubt it. I pay close attention to all functions.

OBD port with a blown fuse will not cause a CEL. You just won't be able to monitor or communicate with the vehicles modules via a Tech II.

Well, mine light up & fuse was blown by cig lighters' short to ground...

Coincidence ? edit: after further study, I have to believe it is a coincidence.

power plug fuse
 

I also have a fuse that blows want to replace plug in dash. Hdo you get the front bezels out without breaking something thanks 2007 HHR lt

grab into the air vents and yank.

well so i pulled both fuses suggested and when i plugged them back in now i dont have power to my outlets..i tried replacing the fuses with new ones and still dont work..wat happened?? :s

Just found this thread.

If you decide to replace the well as I did, because there were burn marks(arcing) on the inside, also rust. If you go with an aftermarket (think autozone, pepboys,etc) before you start, get a couple of 7/8" ID X 1 1/4" OD thin washers, unless you can get the bezel off of the old port. 2006LT, underhood panel, #29=LTR(15A)front, #30=PWR outlet(30A)rear.

FWIW...If you are replacing with stock one, you may not have to remove the trim piece, look inside the well, you will see a grove, turn the groove to about the 1;o clock position, turn back, and forth while pulling out, the tab that holds it in place will line up with a notch and it may come out that way.

Hope this helps..Bill

GM sells the OEM one for about $1 more than the ones you have to "modify" to work. There is also a special tool made for it.
