Greetings,

My heater/AC display light has begun erratically blinking and fading in and out of brightness ONLY WHEN THE DRIVING LIGHTS ARE ON.

The heating/AC display has a brand new bulb.

On the rare occasion my radio and heater have failed to turn on after I started the vehicle. I have jiggled the key in the ignition and they turned on.

Any suggestions?

Thanks

 

On What vehicle??????????????????????????

 

The vehicle is a 2002 Land Rover Discovery. Sorry, my class was walking in and I forgot to include that bit.

 

get the cylinder rebuilt, its possible the ignition switch might be sticking.
