Vauxhall Insignia buzzing noise

Hi

I am having a problem with vauxhall insignia ecoflex when driving 2nd 3rd or 4th gear i sometimes hear a buzzing sound from underneath the car around the engine compartment its like something switching on and then goes of.

2nd issue is the climate control switch, some time i am unable to control them as the lights around the switch go of the blower will stay on what ever setting it was previously on, but i can not turn the blower up or down but if i tap the controls the the lights turn back on and i can control the blower.

any ideas on the two issues
