When you say nothing is happening, I'll take that to mean t just that. The cluster of knobs is bad now. Checking fuses/relays first, then replace the cluster.
Hope this helps

Check your coolant level. If the coolant level is down below where the heater hoses connect to the cooling system, no hot coolant will flow to the heater and you will have no heat. If your fan still operates but blows cold air, this is probably the cause.
