Need help on my power windows that are broke!
Need help from some power window experts. My truck is 2007 GMC 2500 CC SLE Classic. The 2 rear power windows wont roll down any way I try it. They wont go down by the buttons in the rear, nor the main...

jbres, are the power seat controls working? If not it's almost certainly a fuse.
The 3 fuse panels are:
1. Under the hood.
2. Under the dash, to the left of the steering column.
3. On the left side of the dash. Open the driver's door and look for the access cover on the side of the dash.
Look in your owner's manual for the applicable fuses and circuit breakers. There are also maxi-fuses under the hood labeled MBEC and LBEC that protect groups of components and one of those could be blown.
To test a fuse, get a multimeter and set it to ohms (resistence) to check for for continuity. Pull the fuse and put the two leads from the meter on the two fuse prongs, one lead on each prong. If the fuse is good, Ohms of resistence will go to zero on the meter, indicating that there is continuity inside the fuse. If the fuse is bad, there will be no change on the meter.
If you can't find any bad fuses, the next place to look is the switch panel on the driver's side door, that module may have gone bad. Peeps, not sure why you start with the BCM, I like to start with the cheap components first and work my way up the $ food chain....since the windows stopped working suddenly and as a pair, I would suspect a fuse.
