Its possible there is a problem with the catalyst system.I would recommend having your catalytic converter checked to see if its bad.

What does it mean when the service engine light is blinking in a 2005 Pontiac g6?


most of the time when your check engine light blinks it means your having a converter melt down. you need to find out the cause of it. most of the time its something to do with your emission system. a simple computer diag from a local parts store might tell you what sensor is not working right. or you can go to your mech and it will only take a min to check out the codes.

I need to know which fuse is for the 12v in an 05 pontiac g6. I know its in the left of the trunk but just need to know the code for the fuse.


All the fuses are 12V in your car. I am assuming you mean the fuse for the cigarette lighter and auxilliary power outlet. It is fuse #20 in the rear fuse block. It is marked "CIG/AUX". It should be a blue 20 Amp fuse.

The newer Pontiacs (& Chevy Malibus) have a sealed transmission, which means that there is no dipstick for the transmission. Consult your owner manual.
