Trying to repair horn and cruise control failure.
When pressing horn button, relay clicks somewhere under dash but could not
yet locate where. Did not find horn itself either. Can someone tell where
are those located ?
Cruise main unit seems to be behind battery, vacuum hose goes through
firewall but could not locate where. There's probably a vacuum pump under
dash. Is it so that the vacuum pump should start whenever cruise switched
on, even if the car not moving ? Any ideas about typical failures (switches
on steering wheel, vacuum pump, control unit, accelerator cable, brake
light switch et.c.) ?
