My truck just got work done on it and it was in the shop for 6 days and I’ve had it back for 4 days and my battery drained, and I had to recharge the battery. Well, that was yesterday, and it hasn’t drained again, but my radio just won’t turn on and I’m wondering if it’s a fuse, but I changed out a blown fuse and it still doesn’t work. So, could it be a relay? I heard it can’t be but I’m unsure. I just can’t think of what else I should look at.

Hi,

What type of work was done when it was in the shop for six days? Also, when you checked the fuse, did you also confirm there was power to and from it? If not, I need you to check for power.

Here is a link that explains how it's done:

The power to the central junction box in the vehicle comes from a fuse under the hood. So, you could have a good fuse, but no power is getting to it. See fuse 20 below.

I attached the wiring schematic below (pics 1 and 2) so you have a reference. Check the fuse first (the one I circled), and then check the others as well. Note for power to be at.
