Slide out problem
We arrived at the camp site today in our 2012 Tour 42QD. This has happened before but not this bad. After I levled I went to extend the slides and the LED light showing to engage the parking brake kept coming up. In the past I would release the brake and reset it and all was good but not this time. I reset the control, I turned off the power switch and I would still get the led showing set the parking brake. I went to the fuse box and switched the fuse for the parking brake with the one for the horn,(they are the same size and number) and all worked great. Are you thinking the fuse went Bad?
