I have been having some issues with a DC 24 I received from a friend. The brush bar stopped working and they didn't want it anymore. I searched the forums and thought I had tracked down the problem to the tilt switch. I first swapped the switches for the main power and brush power up at the top and they seemed to function fine. I went down to the "upright switch" and found that if I bypassed the switch the brush bar would function. I ordered a new switch but when I installed it I still had the same problem. I started checking the functioning of the switch manually on the switch itself, and there didn't seem to be a problem. It seemed the reclining of the vac itself was part of the issue. I found that the brush bar would run as I tilted the vac back, but it would cut out again when the handle was fully reclined. I'm not sure if this is a wiring issue, or if there is another switch that I am missing somewhere. Any ideas would be greatly appreciated!
