Pulled the radio fuse on my 2009 Colorado and put a meter on it to see if current ran through it with ignition off. Meter showed nothing .Put the fuse back in and now the radio does not work. The fuse is good.

Why'd you pull the fuse in the first place and how do you know it is good?

Are you sure you put the fuse back in the correct slot?

I checked it with a meter and there is current running through the fuse.

You can't easily check for current flow through a fuse... you normally check continuity with an ohm meter. In any case, do you have a volt meter? Is there voltage on both the power and memory wire of the HU?

That vehicle does not provide a switched power source. Did you attempt to install an aftermarket radio?

OK, not to belabor the point, but what exactly did you test? And with what meter? What was the reading?

Why did you pull the radio out? Was it working before you pulled it out?
