Which did you get or did you get both?

Customer: replied 8 months ago.
I've got both
Expert:  kalamykid replied 8 months ago.

Please connect the wire from the test light to a good ground, and with the ignition switch in the run position, test ALL of the fuses in both fuse boxes by touching the tip of the test light to the metal pieces sticking up through the top of all the fuses. Please tell me what fuses have power on just one side, and what fuses have no power to them at all please.

Did you test the fuses in the fuse boxes on both sides of the dash board? You will have to pull the covers off of the end of the dash board where the door meets the dash to get access to the other two fuse boxes.

Every thing that should have power to it does Now we have to do some tough testing. You will need to remove the instrument cluster to do some of the testing. The first thing I would like you to do will be a 30 minute relearn on the security system. I need to know what the security light does when you do the relearn please. Here are the steps I need you to follow please.

Hey Kalama kid I couldn't get away today, Did you figure out any thing from the fuses not liking up
Expert:  kalamykid replied 8 months ago.

All of the fuses look good. The ones that did not have power should not have power as they are not turned on such as the brake lights and wipers. I am sorry I was not online when you where here. Can you let me know when you will want to get together so we can do some testing?
