I have heard this problem related to my sons 2000 Monte Carlo. I'm about to change his ignition switch. I tried the resistor, tested the fan, even changed out the whole climate control unit!
Ignition or ignition switch could be bad or the selanoid could have went out
several could bes. If there is no action, the engine does not turn, the rod running from the key switch to the ignition switch on the column could be broken, or the ignition switch itself could haved malfunctioned. If there has be work immediately privious to the problem, check for loose connection, expecially on the ignition switch.
Defective ignition switch.
Yes, it could.
Something is keeping power to the ignition coil. You need a wiring schematic and trace the wiring.
faulty switch
Check fuses Could be a defective ignition switch
There could be numerous problems that may cause this fault. Personally, my blinkers started going out (working sometimes and sometimes not) and what I found out is this...The flasher switch that is located in the dashboard above the radio is faulty. When my blinkers do not work i just tap down on the flasher switch without turning it on and my blinkers work again. Shotty electrical work in this car if ya ask me.

Bulbs? Sockets? Steering column switch?

The ignition switch could be the problem. Jiggle the keys a bit. As the switch ages it doesn't "sit" quite right. I know this was the problem when some of my stuff wouldn't work, like wipers, heater fan or power windows. Switch might have to be replaced at some point.
It could be the high speed heater motor relay is stuck on or the switch itself is broken.
Depending on the way the vehicle is wired, it could be a bad ignition switch or a stuck relay. You'll need to look at a wiring diagram to find out how power is supplied to the blower and AC system. Then go backwards to find out what's on that SHOULDN't be.
COULD BE A BAD HEATER CORE COULD BE A BAD HEATER CORE sounds like the heater control switch needs replacing.if that doesnt fix it, you need new heater core
The problem could be that your flasher switch is going out. I had the same problem on my 99 blazer. It sounded like a bee buzzing in my dashboard. Had the switch replaced and problem was gone. Hope this helps.
it is an ignition problem...could be the ignition switch or the ignition coil if i rember right
