ELEKTRONIKPROBLEM: blower, ABS lamp, manual brake control

Hello, we’ve been having the following problem for a few days: blower doesn’t work, ABS control lights up, therefore ABS doesn’t work, hand brake control lights up. Not always, but often. Just come up together. When the control lights are off, ABS and blowers go. Also noticed: when giving gas blowers went on, when taking gas away or braking blowers went off. Hangs with gear or movement together, because in the empty run (gap/take off) it doesn’t spark. in the latter fa ll the control lights remained on. Although it does not have anything to do with it, the brake lining HL outside is held only by a pin, the second is stuck next to it in the empty, the layer sits crooked on the disc, but does not block. Must have been like this since purchase (used) in 2006. Would be grateful for ideas.
