Hey fellas need a little advice,

I'm switching out my rear view mirror console out of my 98 for a console from a 99, I'm getting no power to the map lights. I tried testing the power wire with a voltmeter to make sure it was getting power but I got no voltage, I did this with the truck turned on and off. The sunroof switches work just fine. Any ideas would help out. Thanks.

 

The most common problem is a bad ground. Make sure that you have completed a circuit, otherwise charges (electricity) will not flow! Trace the wire back, and make sure that it is spliced to a hot wire. Check the hot wire with a volt meter first. Recheck connections.

 

got it figured it out, I didn't have a good enough ground. Figured this out the hard way and blew the fuse. Oops! Got lights now!
