blowers intermittently working

[micko]

ok guys my blowers work with ignition on but when i start the car they go off 90% of the time? sometimes come back on
if i have been driving for a while,when they go off the red lights on the controls all go off,when they work they work on all speeds
air con works ice cold ect,checked fuse seems ok,check wire to blower all fine,do you think it could be the panel?

It could be the panel or it could be something else, could be the H-VAC control box behind the radio screen.
